Accurate range-based distributed localization of wireless sensor nodes using grey wolf optimizer

Various ranging techniques are frequently employed in wireless sensor networks (WSNs) to determine the distance between a node and its neighboring anchor nodes. The measurement, as mentioned earlier is subsequently estimate location of whose unknown. present paper presents an Accurate Localization Scheme that utilizes Grey Wolf Optimization (GWO) based on Radio Signal Strength (RSS) technique. efficiency our technique has been proved through extensive simulations, showing consistent improvement localization accuracy ratios decrease errors while maintaining cost-effectiveness.
