WSNs consist of small sensor nodes which have limited battery power, limited processing capability and limited memory unit. Self-organization and the lack of infrastructure are regarded as two significant features of WSNs. These features make sensors an appropriate choice and alternative for many applications. Features and limitations of WSNs should be taken into consideration in investigating WSN algorithms and protocols. However, recharging battery in sensor nodes is either impossible or very difficult. The main concern in designing WSN algorithms is to ensure about energy efficiency and lifetime of sensor network. In most cases, a sensor node located in a set of sensor nodes decides that which task should be done and determines the number of unique communication paths among sensor nodes. Large number of lost paths leads to energy imbalance among the nodes. In this paper, using soccer league competition algorithm, we proposed a clustering method which was able to optimize power consumption and reduce delay. The results of simulating the proposed method indicated that it performs better than NODIC protocol.
