QPRR: QoS-Aware Peering Routing Protocol for Reliability Sensitive Data in Body Area Network Communication

Show Summary Details

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 quality of service (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 3.2 to demonstrate the better performance of the proposed QoS-based routing protocol for reliability sensitive data in terms of lower network routing traffic (Hello packets) overhead, less reliability packets dropped, lower end-to-end delay (latency), less packets dropped due to media access control (MAC) buffer overflow and higher throughput in both stationary and movable patient scenarios. The scalability of the protocol is demonstrated by using two cases that simulate a 24 beds and a 46 beds real hospital environment with a 49 and 93 nodes, respectively. It is shown that, even in the larger real hospital scenarios, simulating a hospital with 24 and 46 beds requiring the transmission of critical data packets with stringent reliability requirements, QPRR outperforms comparable protocols.
