It has been proved radio sleep can significantly prolong the lifetime of wireless sensor networks; however, sleep causes more multi-hop latency and fewer throughputs under heavy load. This paper proposes a dynamic sleep MAC protocol LD3-MAC for wireless sensor networks, which uses global schedule, stagger sleep and periodic synchronization to achieve sleep coordination. The dynamic listening scheme...
In this abstract, we present Advertisement MAC (ADVMAC), an advertisement based MAC protocol for wireless sensor networks. Simulation results show that ADV-MAC provides a better way to conserve energy and at the same time to support variable traffic loads.
Despite much research on sensor networks in general and on event-response applications in particular, simultaneously achieving the desired timeliness of response, longevity, and wide-area coverage still remains a significant challenge. In this paper, we present a robust, flexible, and extremely energy efficient sensor networking system solution with the goal of enabling orders of magnitude improvements...
This paper introduces I-MAC, a new medium access control protocol for wireless sensor networks. I-MAC targets at improving both channel utilisation and energy efficiency while taking into account traffic load for each sensor node according to its role in the network. I-MAC reaches its objectives through prioritized and adaptive access to the channel. I-MAC performances obtained through simulations...
