Weiren Shi · Jisuanji gongcheng · 2008
Because the lifetime of Wireless Sensor Networks(WSN) is restricted by the energy of nodes, this paper presents an energy saving algorithm based on cluster head prediction.The approximate linear relationship between the length of data packets and energy consumption for sending, receiving and processing data is analyzed, and an energy consumption model with energy saving algorithm is given.According to the historical fused data, the data of cluster heads is predicted through grey prediction algorithm.With the energy saving algorithm, the communication frequency between cluster head and non-cluster head node is reduced, and the round cycle of cluster head is prolonged at low energy cost.The simulation results demonstrate that the algorithm is efficient for reducing dead speed of nodes and increasing the network lifetime.
