Multi Channel MAC Implementation for Wireless Sensor Networks

In this work, a Multi Channel Medium Access Control (MAC) has been implemented in PICSENSE wireless sensor network hardware platform. A measurement based dynamic channel allocation has been proposed in a dedicated control channel based multi channel medium access control protocol. The implementation has been done with three channels, a control channel and two data channels. Throughput and latency has been taken as the performance metrics and the throughput and latency performance has been compared with that of single channel MAC. And the results show that the proposed multi channel MAC has higher throughput and lower latency than the single channel MAC at high traffic conditions.
