中文说明：这个资源包含了无线传感器网络直接传输能源协议。在此matlab代码，一个100节点的随机网络是在一个100×100区域产生。所有的节点都具有相同的初始能量焦耳。该基站是在网络的中心。所有节点直接发送有数据到基站，而不多跳变。图中示出了活节点的数目与循环数。
English Description：
This resource contains a Direct transmission Energy protocol for wireless sensor network. in this matlab code, a 100 node random network is generated in a 100* 100 area. all the nodes have equal initial energy in Joules. the base station is at the center of the network. all the nodes send there data to the base station directly without multi-hopping. the graph shows the number of alive nodes vs. the number of rounds.
