Congestion avoidance and energy efficient routing protocol for WSN healthcare applications

Abstract

Recent advances in wireless sensor technology facilitate the development of remote healthcare systems, which can significantly reduce the healthcare cost. The use of general and efficient routing protocols for Healthcare wireless sensor networks (HWSN) has crucial significance. One of the critical issues is to assure the timely delivery of the life-critical data in the resource-constrained WSN environment. Energy, and some other parameters for HWSN are considered here. In this paper, a data centric routing protocol which considers end to end delay, reliability, energy consumption, lifetime and fairness have been taken into account. The Proposed protocol which is called HREEP (Healthcare REEP) provides forwarding traffics with different priorities and QoS requirements based on constraint based routing. We study the performance of HREEP using different scenarios. Simulation results show that HREEP has achieved its goals. © 2010 Springer-Verlag Berlin Heidelberg.
