Duty Cycled Multi Channel Mac for Wireless Sensor Networks

In this work, Duty Cycled Sensor Multi Channel (DC-SMC) Medium Access Control (MAC) has been proposed for wireless sensor networks. The DC-SMC MAC uses a dedicated control channel and multiple data channels. The effective solution for the multi channel hidden terminal problem and missing receiver problem has been proposed in this work. The performance of the DC-SMC MAC has been compared with that of the single channel duty cycled CSMA/CA MAC by taking the throughput and latency as performance metrics. It has been shown that the duty cycled multi channel MAC gives high throughput and less latency even with lower duty cycles.
