Adaptive Energy Efficient Cross-Layer TDMA-Based MAC Protocol in Wireless Mesh Sensor Networks

Article Preview

Abstract:

Based on TDMA sleep scheduling scheme, by collecting cross-layer routing information and feedback information, according to the detection of routing information and neighbor information, the sleep slot and data transmitting slot are assigned orderly on TDMA based channel by Mesh router. The sending and receiving mutual interference collision is eliminated by slot allocation with collision avoid method. Moreover, path wake up strategy in terms of the nodes hop are introduced which can assign listen frame and wake up slot better. As a result, a TDMA-based energy efficient cross-layer MAC protocol for wireless mesh sensor networks are proposed, and then the performance of the protocol are analysis by simulation. The study results show that based on WMN and WSN, WSN and WMN can be constructed to achieve a full interconnection network named WMSN.TCP-MCA protocol can effectively reduce idle listen time of node which reduce overall energy consumption of the network.
