Abstract

Challenges faced by Medium access control (MAC) protocols for Wireless Sensor Networks (WSNs) include energy efficient operation and bandwidth limitations. Low duty cycle MAC conserves energy but at the same time it affects delivery ratio and latency. Use of multiple channels can improve the throughput and latency by alleviating the bandwidth limitations. This paper presents the design and performance evaluation of PW-MMAC (Predictive Wake up Multi-Channel MAC) protocol which addresses these challenges by coupling the benefits of multiple channels with adaptive duty cycling and predictive wake-up mechanism. PW-MMAC significantly improves energy efficiency and channel utilization by adapting dynamically to varying network conditions without the need of a dedicated control channel. Implemented in ns-2, PWMMAC shows significant improvement over other duty cycle MAC protocols. PW-MMAC achieves lowest duty cycle, 100% delivery ratio, and lowest packet delivery latency in different network scenarios in both multi-hop and single-hop clique, grid, and random networks.
