Improved LEACH Protocol for Efficient Transmission of Data in Wireless Sensor Networks using Ant Colony Optimization Algorithm

Energy Efficiency is one of an indispensible concern in Wireless Sensor Networks (WSNs) which minimizes their efficiency and also shortens the lifetime of network. Many efficient routing as well as algorithmic schemes are proposed in last decade which help in prolonging the lifetime of a network by reduces the consumption of battery by the sensor nodes. Among all the proposed routing schemes, the concept of hierarchical routing plays in important role to overcome the energy efficiency problem of a network. In this paper, an improved version of highly efficient hierarchical routing protocol LEACH is proposed which reduces the consumption of power from the battery by the nodes which help in increasing the lifetime of a network along with Ant Colony Optimization (ACO) algorithm. The simulator used is MATLAB. The Comparative analysis between LEACH and Improved LEACH protocol has been carried out showing that the nodes in Improved LEACH are covering larger rounds which give the efficient outcomes in prolonging the lifetime of the network. The simulation results also reveal that the proposed Improved LEACH protocol outperforms the performance of conventional LEACH protocol in terms of average remaining or residual energy.
