提出了一种无线传感器网络中的Gossip算法,该算法能充分利用无线网络的广播特性来加快收敛速度.通过叠加编码的处理,增大了有效通信半径,使无法获得完整发射信息的节点获得部分发射信息,且这部分信息可以有效加快信息的传播速度,从而达到加快算法收敛速度、节约传感器能量消耗的目的.理论分析及仿真验证表明:基于叠加编码的Gossip算法可以有效加快收敛速度,同时通过对叠加编码通信半径的调整,可以在收敛速度与收敛精度之间取得平衡.
A Gossip algorithm in wireless sensor networks is proposed, which can make full use of the broadcast characteristics of wireless networks to speed up the convergence rate.With the stacking coding, the effective communication radius is increased, so that the nodes that can not get the complete information are obtained And this part of information can effectively speed up the speed of information transmission, so as to achieve the goal of speeding up the convergence speed of the algorithm and saving the sensor energy consumption.Theoretical analysis and simulation results show that the Gossip algorithm based on overlay coding can effectively speed up the convergence rate, The adjustment of the overlay coding communication radius can strike a balance between the convergence speed and the convergence accuracy.
