Middleware implementation in MANET of Android Devices

Journal of Communications, 2006

The use of middleware has extended from simply facilitating applications' communication to a broad set of services supporting a huge spectrum of networked and distributed computing environments. At the same time mobile wireless ad hoc networks (MANET) have become a popular distributed environment and its application domain is expanding rapidly. However, like all distributed environments several issues must be considered and many problems have to be addressed to have efficient and useful applications. Current researchers moved towards using middleware to provide solutions to these issues and simplify application development for MANETs. In this paper we cover the latest trends and developments in middleware for MANETs and survey these approaches to identify their qualities and limitations. We then classify these approaches into six categories that group them based on the communication models and the programming paradigm used. The paper also evaluates these approaches in terms of the identified categories such as support for mobility, openness and heterogeneity, and the ease of use. Finally, we try to identify the open issues and the possible research directions that would provide better middleware solutions for MANETs. also over eight years of industry experience in systems integration and middleware.

Starting with API level 14, ICECREAM SANDWITH, Android introduced API for peer to peer communication using Wi-Fi Direct. Since then many applications have been released that use this technology for data transfer and communication between two devices. But most of these have been used for just two-person communication. In this paper we propose to create a peer to peer network using the same technology. This paper focuses on creating a local wireless network of android smartphones using Wi-Fi direct. This paper also defines an algorithm using which each device can get the IP address of each of its peer. This paper will also help those who are trying to create applications on android using Wi-Fi Direct.

The smart devices are extremely useful devices that are making our lives easier than before. A smart device is facilitated us to establish a connection with another smart device in a wireless network with a decentralized approach. The mobile ad hoc network (MANET) is a novel methodology that discovers neighborhood devices and establishes connection among them without centralized infrastructure. Cloud provides service to the MANET users to access cloud and communicates with another MANET users. In this article, I integrated MANET and cloud together and formed a new mobility model named Cloud-MANET. In this mobility model, if one smart device of MANET is able to connect to the internet then all smart devices are enabled to use cloud service and can be interacted with another smart device in the Cloud-MANET framework. A middleware acts as an interface between MANET and cloud. The objective of this article is to implement a middleware in Cloud-MANET mobility model for communication on internet of smart devices.

The evolution of wireless communication and information technologies is pushing the tendency of computing to become pervasive, ubiquitous and mobile. In the near future, users will be able to access information while roaming and to interact with the surrounding environment through zero-configuration software. An emerging communication support for this scenario is based on mobile ad-hoc networks (MANET), a network type lacking fixed infrastructure. In these networks, using link-layer technologies such as IEEE 802.11b or Bluetooth, a multi-hop connectivity allows each host to reach hosts beyond the radio range through the use of routing provided by neighboring hosts. Thus, MANETs are able to provide impromptu communication in a highly mobile and changing environment. The highly dynamic nature of MANETs together with the scarceness of capabilities and resources of mobile devices give rise to challenging application design problems: As the environment changes, applications must be able to interact with previously unknown software and devices, and to adapt their behavior to available resources and runtime conditions. In this paper we focus on two services that, in our opinion, should be included in a middleware for a MANET setting in order to achieve application flexibility and adaptability. The core services are: Support to logical mobility that is the ability for an application to dynamically reconfigure itself by moving software components, such as code and/or objects, from a node to another.

Abstract Complex and decentralized information systems need advanced communication services at the middleware level in order to leverage context-aware distributed applications working, for example, despite node mobility and in a setting where such services can be billed. In this paper, we present a middleware architecture offering a communication service which, in its more general case, is able to provide connectivity between two nodes belonging to distinct mobile ad-hoc networks by taking user profiling into account.

Smartphone ad-hoc networks have been deployed for communication where infrastructure based communications are not available (or desirable). Android OS ad-hoc networks can be employed in development of collaborative applications such as entertainment systems and mobile gaming. In addition, they facilitate ubiquitous computing in areas such as home applications where wireless sensors and actuators are embedded in consumer electronics. This paper presents an implementation of Service Discovery middleware for Android Mobile ad-hoc networks. The implementation overlays a Mobile Ad-hoc Network implementation. It further describes a routing implementation that is based on the Ad-hoc On-Demand Distance Vector protocol, with modifications to reduce control message overhead. An implementation of a Semantic approach for description of services on mobile devices, that facilitates semantic service discovery in Android OS Mobile Ad Hoc Networks is also presented. The implementation was tested by simulating the routing implementation. An Android based prototype was developed and tested on a range of devices.

A mobile ad-hoc network (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network. A MANET is a type of ad hoc network that can change locations and configure itself on the fly. Some MANETs are restricted to a local area of wireless devices (such as a group of laptop computers), while others may be connected to the Internet. The set of applications for MANETs is diverse, ranging from small, static networks that are constrained by power sources, to large-scale, mobile, highly dynamic networks. The design of network protocols for these networks is a complex issue. Regardless of the application, MANETs need efficient distributed algorithms to determine network organization, link scheduling, and routing.

With the proliferation of Android smart phones, it should be possible to set up Mobile Ad-hoc Networks (MANETs) to share information anywhere, anytime. To achieve this goal, it is necessary to have a good wireless communication technology capable of responding to the characteristics of MANETs. Wi-Fi Direct could be a good candidate not only because it allows direct communication between devices without the need for a fixed infrastructure but also because it is present in most smart phones with at least Android 4.0. The study of Wi-Fi Direct has been the subject of several works that denounce the limitations of the technology in terms of construction of large-scale mobile networks. In this paper, we make a detailed technical study of the Wi-Fi Direct framework on Android Operating System to understand how it works and its implementation in order to really overcome their network restrictions. We also provide a formal specification of Wi-Fi Direct on Android by using Z and Object-Z specification languages. This study allows us to understand the functions and the classes of the framework and see at what level changes can be make to implement other solutions.

Information sharing is a mission critical key element in rescue and emergency operations. Mobile ad-hoc networks (MANETs) could provide a useful infrastructure to support information sharing, but appropriate applications are needed. To facilitate efficient application development for this type of infrastructure, middleware support is needed. In the Ad-Hoc InfoWare project, we are currently developing corresponding middleware services. In this paper,

It is now commonplace for a person to use lightweight wireless computing devices, and to make his/her data available to other people's devices using todays various networking capabilities (infrastructurebased WLAN, ad hoc WLAN, GSM, etc.). Middleware platforms initially developed for stationary distributed systems cannot be directly applied in such a mobile environment. They must adapt their functionalities so as to best cope with possible resource constraints (energy, storage) of mobile terminals as well as with the various types of wireless networks that are now available. In this paper, we present a middleware service that allows collaborative data sharing among ad hoc groups that are dynamically formed according to the connectivity achieved by the ad hoc WLAN. Our service enhances, in particular, data availability within mobile ad hoc collaborative groups, and integrates a new adaptive data replication protocol for mobile terminals, combining both optimistic and conservative schemes. Our service has been designed so as to minimize energy consumption and optimize data availability and storage consumption.
