OCT的性能分为由其原理所决定的基本特性和外界因素影响下的实际性能。

MEFP periodically selects cluster heads according to the node residual energy,incurs low message overhead,achieves fairly uniform cluster head distribution across the network,and the regular node joins the cluster which has the minimal energy-forward among cluster heads,this tactic can avoid forwarding sensing information circuitously.

提出了一种转发能量最小的无线传感拓扑算法MEFP（Minimal Energy-Forward Protocol），算法减少成簇的通信开销，在网络中簇半径区域内仅产生一个簇头，保证了分簇的均匀；在普通节点加入簇的过程中，选择转发功耗最小的簇头加入，避免迂回发送数据，降低了能量消耗。
