Towards higher throughput and energy efficiency in dense wireless ad hoc and sensor networks
Additional Document Info
Traditional single-channel MAC protocols for wireless ad hoc and sensor networks favor energy-efficiency over throughput. More recent multi-channel MAC protocols display higher throughput but less energy efficiency. In this paper we propose NAMAC, a negotiator-based multi-channel MAC protocol in which specially designated nodes maintain the sleeping and communication schedules of nodes. Negotiators facilitate the assignation of channels and coordination of communications windows, thus allowing individual nodes to sleep and save energy. Simulation results show that NA-MAC, at high network loads, consumes 36% less energy while providing 25% more throughput than comparable state-of-art multi-channel MAC protocols for ad hoc networks. Additionally, we propose a lightweight version of NAMAC and show that it outperforms (55% higher throughput with 36% less energy) state of art MAC protocols for wireless sensor networks. 2010 ACM.
