In wireless sensor networks, LEACH is often used as an energy saving protocol and extends the network life. However, there are many parameters that affect the performance of the LEACH protocol, one of which is the number of cluster heads. This paper proposes a simple and efficient solution to determine the optimal number of cluster heads in the LEACH protocol. For the proposed solution, the system can achieve the optimal performance between the longest lifetime in the constraint as the largest amount of data transmitted in the network.
