EHOCA: Enhanced Healthcare Aware Optimized Congestion Avoidance Protocol for Wireless Sensor Network Applications

Abstract

Wireless Sensor Network in health care applications is an emerging technology to constantly monitor the ailing patients. Congestion is a major challenge in Wireless Sensor Network which in turn causes long delay, loss of packets, energy consumption etc. This paper has proposed Enhanced-HOCA using the concept of novel RED AQM (Active Queue Management) at data transmission of HOCA algorithm. EHOCA is compared with HOCA and REEP in case of network lifetime, packet loss and bandwidth. The Simulation result shows that it outperforms both HOCA and REEP. The efficiency of EHOCA was evaluated using OPNET simulator.
