Performance Enhancement Of Optimized Link State Routing Protocol For Health Care Applications In Wireless Body Area Networks

Wireless Body Area Networks (WBAN) refers to the network of wearable sensor devices on a human body. The data gathered from the devices are sent to the server to take some action during an emergency. The collected data has to be successfully routed to reach the destination for an health care applications in WBAN. Hence selecting the routing protocol plays an important role in WBAN. Several researchers have proposed many routing protocols for WBAN. In this work, a novel proactive routing protocol called Energy Aware Power Save Mode Link State is proposed that modifies the existing Optimized Link State Routing protocol. The mathematical model is defined to select the best multi point relay node in a network that considers the power save mode state. The experiment is conducted using network simulator NS-3 and the result shows the substantial network performance metrics improvement in the proposed model compared to the existing.
