ERM: Efficient Routing Mechanism to route data in wireless body sensor networks

ABSTRACT Wireless body sensor networks (WBSN) is an extension of Wireless sensor networks basically used in medical field for monitoring patients vital data.WBSNs works for collecting the health related data such as ECG,EEG, Glucose values, temperature etc. from human body and route the data towards the destination so that the patients information can be sent to the concerned person. In the health monitoring system routing has an important role. The data sensed by the sensors need to be routed to the destination effectively. In this work we have proposed a routing algorithm which can be used to transfer the data to destination efficiently. To route the data to the sink multi hop process is used and the cost function is used to find the node next closest node in the route from source to destination. The node with minimum cast function will be selected as a forwarder node. The experiments are done in MATLAB environment and simulation result shows that the proposed scheme provides the better network stability period as well as good throughput.
