摘　　要：文章所考虑的方案是如何让无线传感器网络(WSN)中的传感器把被监视的数据处理、传输到远端的收集器上;远端的收集器可能是已经部署好了的WSNs上收集数据的基地站(BS),如用于地震,海啸,或污染监测等;文章分析使用了分布式和协同波束形成技术(DC-BMF),这一技术把节点作为一个相控阵上的元素,在每个天线节点信号的阶段,元素线性组合以调整整个阵列的定向增益。In this paper the scenario where sensors of a Wireless Sensor Network （WSN） are able to process and transmit monitored data to a far collector is considered. The far collector may be a Base Station （BS） that gathers data from a certain number of deployed WSNs, in applications such as earthquake, tsunami, or pollution monitoring. In this paper, the possible use of Distributed and Collaborative BeaM- Forming （DC--BMF） technique is analyzed, This technique considers nodes as elements of a phased array, where the phases of the signals at each antenna node are linearly combined in order to adjust the directional gain of the whole arrav.
