Nodes need constant detect channel of LEACH agreement in clusters processing. According to strength of the cluster head signal, it determines to join what clusters. This process also needs to consume more energy. On the basis of this agreement, a new algorithm uses CSMA mode in the process of grouping clusters. It introduces a signal intensity threshold to decide that nodes should join what clusters. The nodes still adopt the conversion of work and dormancy state. The new algorithm reduces the receiving nodes. And it processes the signals that cluster head nodes and other nodes send. The simulation shows that the new algorithm consumes lower energy than LEACH algorithm and prolongs the network life cycle.
