摘要：Energy conservation can be the most important concern in the deployment of wireless sensor networks. Among all methods, finding an efficient sleep/transmission schedule must be most effective to achieve energy conservation. There are many researches and solutions for sleep schedule, transmission schedule, or topology/routing creation in the past. Nevertheless, almost none of them can solve all of these problems in the same time. Our prior DMAS protocol could be the first cross-layer protocol that can solve all these problems si- multaneously in a distributed way with very low duty cycle. This paper presents the DMAS protocol and an enhanced version of it named EDMAS. The enhancements of EDMAS over DMAS include significant reductions in transmission latency, packet collision probability, and duty cycle.
