Improving LEACH Protocol Using SFLA Algorithm to Reduce the Energy Consumption of Wireless Sensor Networks

Changing and charging the battery is not possible in wireless sensor network due to the large number of sensors. The main issue in designing the network is the inadequacy of sensors energy resources. One of the most common protocols for reducing energy consumption of wireless sensors is LEACH protocol. Controlling the number and position of cluster head in protocol is considered as a challenge. This article propose SFLA – LEACH protocol. Finally this protocol compared with LEACH, LEACH-C, WEEC, BN-LEACH and GA-LEACH. The results show that this protocol comparing to other mentioned ones increase the wireless sensor longevity and also moderate energy consumption.
