摘要:
针对资源有限的无线传感器网络目标跟踪问题,采用一种基于能量平衡的最优分布式成簇机制,为此引入了基于节点剩余能量标准差的能量平衡指标,将其转化为多目标约束优化问题,并采用二进制粒子群优化算法求取最优解.Matlab仿真结果表明,与基于能耗和扩展卡尔曼滤波的成簇机制相比,采用基于能量平衡的最优成簇机制能在保证跟踪精度和能量平衡的前提下,提高网络寿命近2倍,从而有效地延长了网络寿命.
Abstract:
Focusing on the target tracking problem in resource-constrained wireless sensor networks,a novelenergy-balanced optimal distributed clustering mechanism is adopted by introducing an energy-balanced indexbased on the standard deviation of residual energv of nodes. Then,it is transformed into a multi-obijective con-strained optimization problem,and a binary particle swarm optimization algorithm is employed to solve thisproblem. Simulation results in Matlab environment show that the energy-balanced optimal distributed clustering mechanism guarantees energy balance and tracking accuracy comparing with the clustering mechanisms respec-tively based on the energy consumption and the extended Kalman filter,and that it improves the network life-time of nearly 2-fold,effectively prolonging the network lifetime.
