Abstract: Localization, as a crucial service for sensor networks, is an energy-demanding process for both indoor and outdoor scenarios. GPS based localization schemes are infeasible in remote, indoor areas and it is not a cost-effective solution for large-scale networks. Single mobile-beacon architecture is recently considered to localize sensor networks with the aim of removing numerous GPS-equipped nodes. The critical issue for the mobile beacon-assisted localization is to preserve the consumed power to increase the lifetime. Different path planning schemes have been proposed for localization. In this work, the performance of conventional path planning schemes is evaluated and propose a new spider web based path planning strategy analyzed based on three parameters such as location error ratio, energy consumption, and number of references. NS-2 is used as a simulation tool to evaluate existing and proposed system performance in terms of energy consumption, delay and localization accuracy.
