Problem statement: Health monitoring, telemedicine, military, interactive entertainment and portable audio/video systems were most promising applications where WBANs can be used. However, designers of such systems face a number of challenging tasks, as they need to address often quite conflicting requirements for size, operating time, precision and reliability. Network security is very importan...

Recent technological advances in sensors, low-power microelectronics and miniaturization, and wireless networking enabled the design and proliferation of wireless sensor networks capable of autonomously monitoring and controlling environments. One of the most promising applications of sensor networks is for human health monitoring. A number of tiny wireless sensors, strategically placed on the ...

this paper proposes an efficient network architecture to improve energy consumption in wireless sensor networks (wsn). the proposed architecture uses a mobile data collector to a partitioned network. the mobile data collector moves to center of each logical partition after each decision period. the mobile data collector must declare its new location by packet broadcasting to all sensor nodes. h...

Wireless Body Area N/WS are emerging as important network, applicable in various fields like healthcare etc. In previous paper , we study some techniques like TZS, BPR, energy efficient and Hybrid (LEACH+PEGASIS). These techniques work with some topologies not with all topologies and consume more energy and gives less throughput. But now in this paper work are using two such techniques by makin...

Wireless embedded systems, especially life-critical body-area networks, need security in order to prevent unauthorized and malicious users from injecting traffic and accessing confidential data. Coupled with the security costs in system performance and power consumption, embedded systems are also restricted by the type of security that can fit in their limited memory. To address these issues, w...

A mobile ad hoc network is comprised of mobile hosts that can communicate with each other using wireless links. It is also possible to have access to some host in a fixed infrastructure depending on the kind of the mobile ad hoc network. Mobile ad hoc networks can be realized by different networks such as body area network (BAN), vehicular ad hoc network (VANET), wireless sensor network (WSN). ...

Wireless Body Area Networks (WBAN) also referred to as a body sensor network (BSN), is a wireless network of wearable computing devices. It has emerged as a key technology to provide real-time health monitoring of a patient and diagnose many life threatening diseases. WBAN operates in close vicinity to, on, or inside a human body and supports a variety of medical and non-medical applications. T...
