摘　　要：文章主要为解决EEUC协议在通信量较大时,竞争区域变动幅度不能很好地使节点能量达到均衡的问题。文章提出了非线性竞争区域划分方法,使得竞争半径变动幅度增大,更好地适应高数据率的需要。针对BPEC算法在产生簇头过程中有的节点在剩余簇头节点能量低于邻居节点的平均能量的时候仍可能成为簇头节点,这会使得有的节点很快消耗完能量,为此,文章引入了阈值,既很好地解决了簇头节点连接的问题,也使得节点能量消耗更加均衡。This paper mainly deals with the problem that the energy of the node can not be well balanced by range of fluctuation in competition in the EEUC protocol when the traffic volume is large. In this paper, a nonlinear competitive region partitioning method is proposed, which makes the competition radius amplitude of fluctuation increase, so as to better adapts to the high data rate needs. For the BPEC algorithm, some nodes are still possible to be cluster node when the energy of residual cluster head node is lower than the average energy of neighbor nodes. This will make some nodes drain the energy quickly, therefore, the threshold value is introduced in this paper, which better solves the problem of cluster node connection, and also makes the node energy consumption more balanced.
