Abstract:
In low-power wireless sensor networks, MAC protocols typically use periodic sleep/wake schedules to minimize idle listening time. While this approach is simple and efficient, it leads to higher end-to-end latency and reduced throughput. In contrast, earlier CSMA/CA-based MAC protocols aimed to reduce inter-node interference but at the expense of increased latency and lower network capacity. In this paper, we introduce IAMAC, a CSMA/CA sleep/wake MAC protocol that reduces inter-node interference and minimizes per-hop delay through cross-layer interactions with the network layer. We also demonstrate that IAMAC can be integrated into the SP architecture for effective inter-layer interactions. Through extensive simulations, we evaluate IAMAC's performance across various metrics. The results confirm that IAMAC reduces energy consumption per node and extends network lifetime compared to S-MAC and Adaptive S-MAC, while also offering lower latency than S-MAC. Our evaluations consider IAMAC with two error recovery methods—ARQ and Seda—and show that using Seda as the error recovery mechanism improves throughput and lifetime over ARQ.
