Power Efficient Gathering Sensor Information syste

In PEGASIS, the energy load is the sensor node in the distributed evenyamong network. The initial node is the randomlyin theater, so the I – th node is in the randomlocation. Nodes are organized to form a chain, and any component can be used by the sensor node itself to select a node in Huazhong by greedy algorithm. In addition, BS can calculate the chain and broadcast all the sensor nodes of itto. In order to construct the chain, it is assumed that the global knowledge of the network is preserved and the greedy algorithm is used. The greedy method is used to build the chain, which takes place in the first round of communication. To build the chain, the farthest node in BS is selected.
