Abstract :
Wireless sensor networks are an emerging technology that is designed to support all types of applications. The energy constrained sensor nodes in sensor networks operate on limited batteries, so it is a very important issue to reduce energy. IEEE 802.15.4 is the best choice for the implementation of wireless sensor network. But, in high load conditions due to congestion, energy consumption is increased and throughput is reduced. To alleviate this problem existing queuing system of node is analyzed and modified in the proposed CH-MAC protocol. In this proposed algorithm hybrid MAC of CSMA and TDMA with fair share queuing system is used for better energy efficiency and improved delay performance. The method is evaluated in comparison with 802.15.4 using NS 2. Simulation results indicate improvement in packet delivery ratio, energy consumption, and delay performance.
