Analyzing and improving the energy efficiency of IEEE 802.15.4 wireless sensor networks using retransmissions and custom coding
This paper analyzes the performance of error control strategies in IEEE 802.15.4 wireless sensor networks. ARQ schemes of the IEEE 802.15.4 are used and also we propose custom coding using BCH codes. The performance is analyzed through simulation using the energy efficiency parameter. Performance results are obtained for multi-hop networks with different channel conditions and packet sizes. The results have shown that the ARQ scheme and BCH codes are energy efficient for networks with high number of hops and low values of signal-to-noise ratio.
