A QoS-aware Routing Protocol for Reliability Sensitive Data in Hospital Body Area Networks

Abstract The reliability, energy efficiency, and real-time display of patient's data are important factors for Body Area Network (BAN) communication in indoor hospital environments. In this paper we propose a novel routing protocol by considering the QoS requirements of BAN data with strict reliability requirements. Our proposed algorithm increases the reliable delivery of critical BAN data at the destination We have performed extensive simulations in the OMNeT++ based simulator Castalia to demonstrate the better performance of the proposed QoS based routing protocol for reliability sensitive data in terms of successful transmission rate, lower network routing traffic (hello packets) overhead, and lower end-to-end delay (latency) in both stationary and movable patient scenarios.
