无线传感器网络响应型数据融合算法

he data-aggregation algorithm at the network layer, which constructs the route from source nodes to the base station, is essential to the energy dissipation by nodes. In order to save energy for reactive wireless sensor networks (WSN), an event-driven reactive data-aggregation algorithm (RDA) at the network layer is proposed and realized. The reactive WSN is event-driven, therefore, according to existing clustering data-aggregation algorithms, RDA periodically clusters based on events. Consequently, RDA reduces the amount of reconstructed clusters and avoids redundant clustering. In comparison with TEEN, the simulation results show that the RDA algorithm reduces energy consumption and considerably prolongs the lifetime of the network.
