Trust aware light weight secure routing protocol for wireless body sensor network using RCP measures

Abstract

The growth of information technology and networking solutions encouraged the deployment of WBSN. It supports the monitoring and control of human conditions towards various issues. However, the security of data transmission and routing plays vital role and to achieve this, different algorithms has been identified. But, the earlier methods are does not produce expected QoS (Quality of Service) parameters. To improve the performance of routing, a novel trust aware light weight routing algorithm (RCP-TLSR (Reputation Completion Privacy Preservation-TLSR) has been proposed. The sensors of wireless body network discover the available routes between the source and destination. The selection of route and the sensor node has been identified according to the RCP measure which has been computed according to the reputation, completion and privacy preservation values. By choosing the routes according to the values of RCP, the method achieves higher performance in routing. On the other side, the data security has been enforced by block level encryption technique which is understandable for the concern sensor nodes. The method improves the performance in security and routing highly.
