Abstract
Conference Title: 2016 IEEE Wireless Communications and Networking Conference (WCNC) Conference Start Date: 2016, April 3 Conference End Date: 2016, April 6 Conference Location: Doha, Qatar In this paper, we propose a new Medium Access Control (MAC) protocol for Wireless Sensor Networks (WSNs) called MMSMAC (Multi-Mode Sensor MAC protocol), which can operate and switch among three modes: synchronous, asynchronous, and hybrid, according to the application requirements. In the synchronous mode, MMSMAC organizes the sensor nodes under even and odd clusters. Each sensor node has its own active/sleep and send/receive periods according to its cluster identifier, which ensures better load balancing among nodes. In the asynchronous mode, sensor nodes communicate freely without the utilization of even and odd clusters. In this mode, we also propose another mechanism to circumvent the hidden host problem. In the hybrid mode, the features of synchronous and asynchronous modes are combined. Simulation results and analysis show that each of the MMSMAC modes shows convincing performance gains and outperforms B-MAC and CSMA/TDMA protocols.
