Oo Estimation Through Automation of the Predictive Object Points Sizing Metric

To efficiently manage the resources various software characteristics like size, cost, quality etc... more To efficiently manage the resources various software characteristics like size, cost, quality etc is being estimated through different techniques and during different phases of software development. One of the techniques is function points measurement but inadequate for object oriented software for prediction of efforts. PRICE Systems has developed a metric called Predictive Object Points which was designed specifically for Object oriented software and result from measurement of the object-oriented properties of the system. It fulfilled almost all the criteria of OO concepts but it was not validated and has not adopted by industry thus has not gained sufficient recognition from practitioners to be used on a regular basis. Predictive Object points have been developed in the context of companies (e.g. Price Systems). But no details about their actual usage in these companies are publicly available. In this paper we discuss the theory behind POP, the problems with it and present an automation tool for measuring Predictive Object Points with more accuracy. The tool and results of its application in an industrial environment are presented and discussed.

Software piracy is a great threat for software industry because of every country losing millions of dollars every year. To protect the software piracy of the software’s, variety of prevention techniques have been developed for copyright protection of software codes using both hardware and software. But, unfortunately no single technique is currently strong enough to protect the piracy of software codes. However, through a combination of techniques software developers are using for better protection of their software codes. In this paper, we have explained various static and dynamic techniques of software watermarking. In static watermarking techniques, the watermarks are stored in the source code, either in data section or code section where as in dynamic watermarking techniques the watermarks are generated during program execution. In this paper we have proposed a combination of static software watermarking techniques for structural programming by equation reordering and function dependency oriented sequencing (FDOS). In this method we embed the watermark in source code by a nested procedure wherein we firstly interchange the safe operands of mathematical equation and secondly impose an ordering on the mutual independent functions by introducing bogus dependency.

Identification of a set of reliability measures and their ranking criteria is the basis of our research. No related appropriate applied data is found in literature; hence each measure's score for each ranking criterion is stimulated through expert opinion aggregation using fuzzy multilevel procedure. The proposed approach has been compared with existing practices. By setting up and practice of ranking of frequently used reliability measures of each component of Mobile Agent based Systems, a reliable quantitative estimate of MAS reliability can be done. With the known ranks of reliability measures, an organization using them will be more relaxed and assured while measuring reliability of Mobile Agent based Systems.

In this paper we focus on 35 measures identified by IEEE for producing reliable software for which 7 ranking criteria considered. The rate of each measure for each ranking criteria collected from 10 experts from industry and the academic field by our online survey portal & then aggregated in to a single rate using the additive aggregation theory. We have ranked the measures and identified top three measures of each software development phases. These measures can be more reliable for software quality prediction.

However, before mobile agent's viable use in MANET, major performance issues such as reliability of Mobile Agent based System need to pay attention. Reliability of a mobile agent can be defined as its success ratio to fulfill its objective. MANET may have some malicious nodes which can affect the reliability of Mobile Agent based System (MAS). To overcome this issue, mobile agent should have some mechanism to find out the presence of these malicious nodes in MAS. Owner host node of Mobile Agent prepares the list of nodes the mobile agent required to visit to fulfill its task. This node list needs to be updated to remove the malicious nodes from the node list. Also, selection of suitable migration policy of agents is also necessary to ensure reliable Mobile Agent based System. This paper focuses on the enhancement of node list, selection of migration policy and MAS reliability based on reinforcement learning. This method helps mobile agent to learn about a preferred policy for selecting a suitable migration pattern and detecting malicious nodes present in the MANET. To measure the reliability of learning mobile agents, a Monte Carlo simulation based algorithm is proposed. Obtained results verifies that the learning of mobile agents contributes towards better reliability of MAS in suspicious MANET.

Reliability is one of the most important issues in mobile agent-based system (MAS) which was addressed by many researchers. In this paper, we enhance the reliability in MAS with the support of intrusion detection system (IDS) and effective routing. Routing is an important process to find optimal path which improves network throughput and reliability. Collision-free (CF) -network graph exploration method is designed for identifying optimal path for MAs. Security is a crucial aspect due to various malicious node activities and must be considered while estimating reliability. In our process, HMAC-SHA1 algorithm is performed for detecting malicious agent and rule-based logic (RBL) is designed to identify malicious host. Further, we calculate reliability of MAS with respect to status of network and its condition which includes link connectivity and malicious node probability. Finally, we are simulating our performance by using various factors such as size of MAS, malicious ratio and number of mobile agents in MAS, etc. These factors are significant to show improved reliability of our proposed system.

The necessities of database replication are expanding with the time as the use of internet is also increasing. With the purpose of meeting these prerequisites, priorities among requests can be included. In this work two types of priorities i.e., low and high priority is considered in this research article. It is noticeable that the high priority requests are more vital in comparison to low priority requests and therefore low priority requests can be delayed or dropped. The rate of request loss can be lessened utilizing the conditions of load balancing where a portion of the contending requests are transferred to other nodes. In this paper, internet is modelled as small world network, and performance assessment of A-PDDRA (Advanced Prebringing Based Dynamic Data Replication Algorithm) is carried out on small world network while considering both priorities and load balancing using computer simulation

A Highly Reliable and Cost-effective Service Model for Finite Population Clouds: Analysis and Implementation

Arabian journal for science and engineering, Jun 24, 2021

Cloud computing is the delivery of on-demand, network accessed and easily configurable computing ... more Cloud computing is the delivery of on-demand, network accessed and easily configurable computing resources on a pay-as-you-go basis. These resources are dynamically assigned and can be scaled up and down in response to users’ needs. An increasing number of businesses are switching to cloud based computing systems for internal uses. Hence, there is a need to explore queuing theory to model systems bound by the constraint of a finite user population. In this work, a model for the analysis of request stage of finite population cloud computing systems has been presented. The losses in the system due to impatient users owing to balking and reneging in the system have also been taken into account in the model. A scheduling method to improve the load balancing of the request stage of the system has been introduced. A cost and reliability measurement scheme has been used to analyse the performance/cost trade-off associated with request stage of the system. The results obtained have been presented and compared with existing model working in the same domain. Experimental results show that improved cost saving (as high as $$\approx 91\%$$ ) and high throughput rate can be achieved by applying the proposed CCRM scheme.

Predicting Design Quality of Object-Oriented Software using UML diagrams

In this paper, we propose an approach for determining the design quality of Object Oriented Software System. The approach makes use of a set of UML diagrams created during the design phase of the development process. Design metrics are fetched from the UML diagrams using a parser developed by us and design quality is assessed using a Hierarchical Model of Software Design Quality. To validate the design quality, we compute the product quality for the same software that corresponds to the UML design diagrams using available tools METRIC 1.3.4, JHAWK and Team In a Box. The objective is to establish a correspondence between design quality and product quality of Object Oriented Software. For this purpose, we have chosen priory known three software of Low, Medium and High quality. This is a work under progress, though; the substantial task has already been completed.

In such a scenario it becomes imperative to study the economics of these systems. In this work we present a micro-economic model to maximize the profit of a cloud service providers. The profits of such firms depends highly on the reliability of the system and the quantity of resources employed. A profit function formulated has been modified to consider the reliability of the system as a major component on the profitability of the firm. The cloud system has been modelled using queuing theory and a profit optimization problem has been formulated using the principles of producer side micro-economics.

The ad hoc network has found a variety of military and civil applications such as battlefield communication, disaster recoveries, conferences, environmental detection, security, pollution sensing and traffic monitoring. Connected dominating sets (CDS) can be regarded as a virtual backbone for wireless ad hoc network and a smaller CDS is designed to minimise the interference problem, control messages and maintenance cost. The objective of designing a CDS heuristic is to reduce the search space to save scarce resources such as bandwidth energy. We discuss few centralised algorithms that have constant performance ratios for its size. We also discuss few algorithms of distributed and localised type. Further, we compare various CDS algorithms in terms of performance ratio, time complexity, message complexity with their merits and demerits and are illustrated in Table .

But the mobility is unpredictable and may cause routes to break frequently. The frequent breaks in routes adversely affect Quality of Service requirement of applications in the mobile wireless networks and thus pose a challenge. In this paper, we have proposed a method for signal strength based link availability prediction to be used in AODV routing. The nodes estimate the link breakage time and further warns the other nodes about the link breaks in the route. Based on this information, either local route repair or new route discovery is initiated much earlier than the route breakage. This reduces the data packet losses as well as end-to-end delay. The proposed approach is compared with AODV without link prediction. The results show that there is significant reduction in packet drops and average end-to-end delay. There is also an improvement in data packet delivery ratio for AODV with link prediction. Proposed approach results in improvement in the Quality of Service.
