Being a pivotal resource, conservation of energy has been considered as the most striking issue in the wireless sensor network
research. Several works have been performed in the last years to devise duty cycle based MAC protocols which optimize energy
conservation emphasizing low traffic load scenario. In contrast, considering the high traffic situation, another research
trend has been continuing to optimize both energy efficiency and channel utilization employing rate and congestion control
at the MAC layer. In this paper, we propose A Load-aware Energy-efficient and Throughput-maximized Asynchronous Duty Cycle MAC (LET-MAC) protocol for wireless sensor networks to provide an integrated solution
at the MAC layer considering both the low-and high-traffic scenario. Through extensive simulation using ns-2, we have evaluated
the performance of LET-MAC. LET-MAC achieves significant energy conservation during low traffic load (i.e., no event), compared
to the prior asynchronous protocol, RI-MAC, as well as attains optimal throughput through maximizing the channel utilization
and maintains lower delay in regard to the CSMA/CA-like protocol during a high volume of traffic (i.e., when an event occurs). |
