Channel polling activity in MAC protocols of wireless sensor network (WSN) significantly governs energy, delay, and lifetime of the network, and therefore, it is required to adjust the polling intervals in accordance with the incoming traffic patterns. In this paper, an asynchronous duty-cycle-based MAC protocol: adaptive and dynamic polling-MAC (ADP-MAC) has been developed. This paper took a novel...
Data aggregation has been an important mechanism for achieving energy efflciency in WSN's. The aggregation reduces the transmission of redundant data which results in improved energy usage. A large number of data aggregation protocols have been developed in the past based on various techniques of optimizing the delay and energy. This paper surveyed the most prominent data aggregation protocols recently...
