Relay Node Based Fault Recovery Technique in IEEE 802.15.4 based WBAN

Abstract

Wireless sensor networks comprises of many individual nodes which interconnect to form a system that operates as one. These sensor nodes play the main task of sensing the environmental conditions and maybe control them too. A WBAN consist of portable, miniaturized, and independent sensor nodes for monitoring body function for health, sporting, emergency and entertainment, applications. It provides long term health monitoring of patients under natural physiological states without constraining their normal activities. In body sensor networks it allows communication between implanted devices and remote monitoring.The proposed algorithm reduces the chances the chances of fault in the network. The proposed and existing algorithms are implemented in NS2 and results are analyzed in terms of certain parameters
