Abstract:

A novel Traffic-aware and energy efficient routing (TEER) protocol based on dynamic source routing(DSR) is proposed in wireless mesh network (WMN). TEER exploits information originated from media access control (MAC) and physical layer as well as that from application layer. To balancing energy efficiency and bandwidth quality of service (QoS) requirement, an integrated metric MTEER is proposed to denote the energy and transmission state of the node. TEER combines the available link bandwidth, duty cycle of load queue and the residual energy of node acquired by statistic methods. Simulation results demonstrate that TEER outperforms the performance than that of energy-aware multi-path routing protocol (EMRP)and dynamic source routing (DSR) in terms of network lifetime and throughput.

Key words: wireless mesh network, wireless mesh network, cross-layer design, traffic-aware, quality of service, routing protocol
