Abstract
In this paper, we propose a hybrid MAC architecture for reducing energy consumption and maximizing network lifetime in wireless sensor networks. For this purpose, the hybrid MAC architecture is proposed for energy efficient by combining inter-cell TDMA and intra-cell CSMA scheme. Based on the ns-2 simulation result, we prove that the proposed architecture improves energy efficiency as compared with CSMA and TDMA.
