摘　　要：针对无线传感器网络的能量空洞问题,提出了一种具有最优簇规模的无线传感器网络不等簇的数据收集协议(UCPOCS)。首先,UCPOCS协议运用定时广播代替传统的消息协商机制竞选簇首。其次,利用候选簇首的位置信息从理论上获得最优簇半径对网络进行不等簇的划分。然后,簇首间多跳路由机制根据其相邻簇首的剩余能量等3种信息选择其中继节点,使UCPOCS能够适用于均匀和非均匀节点分布情况。最后,仿真结果表明UCPOCS协议能够有效地均衡网络能量消耗,延长网络寿命。In this paper,an unequal cluster data gathering protocol with optimal cluster size（UCPOCS）is proposed in order to resolve energy hole problem in wireless sensor networks.First,UCPOCS adopts time broadcast to substitute traditional discussion mechanism to select cluster head.Then,the optimal cluster radius is theoretically obtained according to the location message of the candidate cluster head,which clusters the whole network.Finally,the multi-hops routing mechanism selects the relay-nodes according to three messages of neighbor cluster heads,e.g.residual energy etc,which is suitable for uniform and non-uniform node distribution.Simulation is conducted and results demonstrate that the proposed UCPOCS can balance energy consumption effectively and the network lifetime can be prolonged.
