Wireless sensor network (WSN) is still a developing technology with different aspects. It takes attention of many researchers because of its tremendous resources for internet and users. To be able to manage these resources, multiple protocols and algorithms are developed. Energy efficiency is one of the most important research areas of WSNs in the literature. A Wireless Sensor Network is the collection of large number of sensor nodes, which are technically or economically feasible and measure the ambient condition in the environment surrounding them. The difference between usual wireless networks and WSNs is that sensors are sensitive to energy consumption. Energy saving is the crucial issue in designing the wireless sensor networks. In this paper, a modified algorithm for Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is proposed. The modified algorithm proposed is Enhanced Multihop LEACH protocol i.e. LEGAC (LEACH Genetic Ant Colony algorithm); using Genetic algorithm for head selection and Ant Colony algorithm for routing. The network performance depends on the changing energy consumption of the nodes and degree of connectivity of the nodes according to their distance from the base station.
