A Channel Adaptive MAC Protocol with Traffic Aware Distributed Power Management in Wireless Sensor Networks
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 2
Abstract
Wireless sensor networks are battery operated computing and sensing devices. The sensor nodes will be deployed in an ad hoc fashion with individual nodes remaining inactive for large periods of time but suddenly becoming active on detecting an event. Energy management is a major issue in wireless sensor networks. In this paper, we describe AEMAC, a channel adaptive MAC protocol with traffic aware distributed power management in wireless sensor networks. We evaluate the performance of the AEMAC scheme, over a sensor network with SMAC and ZMAC schemes, in terms of energy consumption, delay and throughput for varying node densities and transmission rates. AEMAC shows a highly superior performance in terms of energy consumption and throughput compared to SMAC and ZMAC schemes.
