Users will have access to multiple networks at the same time. So there is a need that the user should be able to roam seamlessly among the multiple access network technologies. Vertical handover decision algorithms are essential components of the fourth generation (4G) heterogeneous wireless networks. These algorithms should be designed so as to provide the required Quality of Service (QoS) to a wide range of applications. In this paper we are presenting the survey of VHD algorithms designed to satisfy these requirements.

Because of the fast pace, it is a top health concern. Psychologists say that if they don’t learn healthy ways to manage stress now, it could have serious long-term health implications, such as depression, anxiety, high blood pressure, diabetes. Currently people are suffering from stress issues everywhere. Since last few decades stress has been detected in most of the people and there has been recorded severely increasing effect of stress on human body. Stress can alter complete health which leads to reducing the tolerating power of the human. In metro cities this condition is more severe. Hence it is necessary to identify stress before it causes any serious harm and treat on it. In this project we are presenting stress detection technique and lower it with the help of Music therapy. As there are many benefits of music so by taking advantage of it we are minimizing stress level to normal state. Detection of stress using brainwaves is ...

It will integrate the current co-existing wireless networks to allow the users to connect to the network that best suits their needs. The next generation wireless networks are characte rized by anywhere, anytime connectivity, enhanced data servi ces and higher data rates to end-users.

ICT has revolutionized the common man's life. Today we want everything at the tip of our finger which we never had dreamt of. This is an idea of the same. Once a luxury but today a need car has became one of the important assets in our life. The car which gives luxury and helps us out during needy hours many a times risks to unwanted turns. The idea reflects here the avoidance of such risks with the help of next generation networks or specifically sensor networks. The car is controlled by the network depending on parameters like license of the driver, battery, fuel, servicing status, speed of the car. News of traffic jam, congestion on the roads, alerts to avoid accidents, road guide of every instant and medicinal help during undesired events will be provided. Important of all, health of the driver will be monitored and if detected not suitable for driving will be not allowed to drive further. Health of the driver includes his blood pressure, drug level, alcoholic level, brain mapping, heart waves which will lead to caring of the driver, the persons traveling as well as will avoid accidents.

Routing in MANET is very important issue as dynamic topology of MANET makes routing very difficult. This paper shows comparative performance evaluation of two prominent ondemand reactive routing protocols in mobile ad hoc networks: Ad Hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR). Performance is compared on the parameters like Packet delivery ratio i.e. throughput, Average end to end delay and Normalized routing overhead using network simulator-2(NS-2). The general observation of the results indicate that considered protocols react in similar way in low load and low mobility scenarios, but under high mobility DSR outperforms AODV protocol, although DSR and AODV share similar on-demand behavior.

In this paper, we focus on critical event monitoring in wireless sensor networks (WSNs), where only a small number of packets need to be transmitted most of the time. When a critical event occurs, an alarm message should be broadcast to the entire network as soon as possible. To prolong the network lifetime, some sleep scheduling methods are always employed in WSNs, resulting in significant broadcasting delay, especially in large scale WSNs. In this paper, we propose a novel sleep scheduling method to reduce the delay of alarm broadcasting from any sensor node in WSNs. Specifically, we design two determined traffic paths for the transmission of alarm message, and level-by-level offset based wake-up pattern according to the paths, respectively. When a critical event occurs, an alar...

Matched filtering is best. However it requires detailed knowledge of primary signaling. But when no knowledge about the primary user signal is assumed, an Energy Detector is most favorable. Also IEEE 802.22 will provide for spectrum sensing via energy detection. . In this paper we are dealing with different types of

The next generation wireless networks are characterized by anywhere, anytime connectivity, enhanced data services and higher data rates to end-users.

To facilitate new services, and make them flexible and bandwidth efficient, vertical roaming of mobile nodes is a tempting possibility for operators. Our project deals with reduction of power consumption during handovers. If the user call is based on previous history, the handover takes place without calculations and we have achieved a power saving of 28.38%. Also our proposed algorithm tries to select an appropriate target network for handover which will support the battery power of MN with its ongoing application if the call is not regular.

Therefore for Information and Communications Technology (ICT) industries needs the methods to minimize the energy consumption of wireless mobile devices. And hence reduction in CO2 emission is minimized. The energy consumption is directly related to CO2 emission, more energy consumed more the CO2 emission. To control the CO2 emissions, there is different research projects already designed and still work is going on. In this paper, our objective is to discuss the recent methods of CO2 emission control for wireless networks such as WSNs (Wireless Sensor Networks) and (WANs) Wireless Access Networks and so on. Green Communications is perspective of CO2 emission in which major energy consumption reduction is expected by designing the energy optimisation metrics as well as combining the energy ware networks ...

We are able to see the beauty of nature, things which happen in day-to-day life with the help of our eyes. But there are some people who lack this ability of visualizing these things. They face many difficulties to move on with their daily life. The problem gets worse when they move to an unfamiliar location. Visually impaired people face many challenges when moving in unfamiliar public places. Only few of the navigation systems for visually impaired people can provide dynamic interactions. None of these systems work perfectly for outdoors. Propose navigation device for the visually impaired focus on travelling from one location to another. This focuses on designing a device for visually impaired people that help them in travelling independently comfortable to use. The device is linked with a GPS to identify the location of the blind person. Moreover, it provides voice alert to avoid ...

Road accidents are prone to number human deaths. There are different reasons which lead to road accidents, but drivers fatigue or distraction is main threat in major accidental cases. Therefore, recently various methods are explained by many authors for untimely identification of driver sleepiness in the manner of prohibiting mischance on road. In this paper, we are presenting the novel approach called hybrid method in which automatic care of driver safety and hospitality management services. Our approach aims at determining first if a driver is distracted or not based yawing, eye position, head position, mouth position etc., second if driver is detected as distracted instance alarming will perform on both driver side and near hospital services in order to be available in case of accident happen. Based on computer vision techniques, we propose four different modules for features extraction, focusing on arm posit...
