Abstract
In this paper, we design and implement an application-aware, event-oriented MAC protocol (App-MAC) for event-driven multimodality WSN applications. We leverage the advantages of contention-based and reservation-based MAC protocols to coordinate the channel access, and propose channel contention and reservation algorithms to adaptively allocate channel time slots according to application requirements and current events status. To evaluate the proposed App-MAC, we have implemented App-MAC using Berkeley TelosB motes and compared with three state-of-the-art MAC protocols, i.e., S-MAC, TDMA, and TRAMA. We found that App-MAC outperforms other protocols tremendously, including decreasing the average event delivery latency from 3% to 75%, improving the channel utilization efficiency from 12% to 58%, while improving the energy consumption efficiency from 46% to 59%.
