【摘要】：針對無線傳感器網(wǎng)絡(luò)運行過程中出現(xiàn)的節(jié)點能耗不均及網(wǎng)絡(luò)穩(wěn)定周期較短的問題,提出一種改進(jìn)的穩(wěn)定選舉協(xié)議。采用綜合考慮節(jié)點剩余能量和能量消耗率的簇頭選舉機(jī)制,優(yōu)化節(jié)點閾值計算方法,使剩余能量越多、能量消耗率越小的節(jié)點被選為簇頭的概率越大,從而避免能量過低的節(jié)點承擔(dān)較多網(wǎng)絡(luò)負(fù)載,均衡節(jié)點間的能耗。仿真結(jié)果表明,改進(jìn)協(xié)議能有效降低網(wǎng)絡(luò)能耗,延長網(wǎng)絡(luò)壽命。
[Abstract]:An improved stable election protocol is proposed to solve the problems of uneven energy consumption and short network stabilization period in the operation of wireless sensor networks (WSN). A cluster head selection mechanism considering the residual energy and energy consumption rate is adopted to optimize the node threshold calculation method. The higher the residual energy, the higher the probability that the node with lower energy consumption rate is selected as cluster head. In order to avoid too low energy node to bear more network load, balance the energy consumption between nodes. Simulation results show that the improved protocol can effectively reduce network energy consumption and prolong network life.
