Abstract

Event-driven data aggregation (EDDA) scenario is widely applied in wireless sensor network (WSN) applications. In this paper, we present a MAC protocol of WSN for EDDA scenario, referred to as E-MAC. Different from other MAC protocols, E-MAC is designed upon the attributes of EDDA scenario. E-MAC classifies the nodes in EDDA scenario and divides the transportation of data packets into several stages. Through sequential wake-up, multi-hop reservation and staggering transmission, E-MAC schedules data packets from the event zone across multiple hops in the same cycle. As a CSMA based protocol, it offers favorable performance with a low energy cost in EDDA scenario. We analyzed the latency of E-MAC and RMAC [3] numerically in EDDA scenario. Besides, we evaluated E-MAC in EDDA scenario using ns-2.29 and compared it with RMAC. Results of both the analysis and the simulation state that the advantage lies in E-MAC in EDDA scenario.
