Hybrid Rapid Response Routing Approach for Delay-Sensitive Data in Hospital Body Area Sensor Network

Wireless body area sensor networks (WBASNs) have gained much importance in current research domains and are implemented in real scenarios like hospitals for monitoring patients real-time data. Tiny sensing nodes in WBASNs have limited processing, storing capacity and battery life. The communication of sensing nodes is made energy efficient to conserve the energy of the resource scarce WBASNs. In our paper, we have proposed a routing protocol known as Hybrid Rapid Response Routing (HRRR) protocol for delay-sensitive traffic such as real-time health related data of patients. Time-critical data is forwarded with much less delay due to the minimization of end-to-end delay. Large coverage area of HRRR protocol made its implementation possible in hospital environment to gather the patients data. Therefore, our proposed scheme best fits the requirement for WBASNs in hospitals using sensing nodes for communication. Simulations results show that our proposed protocol has shown much improved results in terms of increased network life time, stability, throughput, and energy efficiency as compared to other existing routing protocols of WBASNs.
