To reduce energy consumption while nodes are competitiving cluster head in WSNs clustering routing protocol and solve the problem of unbalanced energy consumption

present a novel uneven clustering algorithm based on time delay mechanism. This algorithm can guarantee the node with high remaining energy to be chosen as the cluster head nodes in priority

besides this

propose computation method of cluster head competitive radius

to ensure a constant number of cluster heads and the cluster heads are well scattered. In cluster process

nodes select cluster heads according to least consumption function

while in cluster member is joining in

consider factors of energy of cluster head

distance and clusher head and sink node angle. Simulation results show that the algorithm can effectively balance energy consumption of nodes

prolong network lifetime

it prolongs 35. 1 % and 12. 9 % lifetime compared with CHTD and EEUC algorithm.
