An energy efficient distributed scheduling scheme forwireless mesh networks

Abstract

The usefulness of wireless mesh networks (WMNs) highly depends on the effective usage of frequency spectrum, scalability and energy efficiency of the underlying technologies [1]. While maximizing network throughput for given frequency spectrum, and scalability have been extensively studied in multi-hop environments, energy efficiency has not received due attention. In this paper, we propose an enhanced pseudo random access (EPRA) scheme based on the IEEE 802.16-2004 distributed mesh framework to improve energy efficiency. Our proposal addresses issues that we identify with the existing election based transmission timing (EBTT) mechanism of IEEE 802.16-2004. Our extensive simulation results s..
