Amrita A. Agashe, Hemant Chavan

Abstract: Due to advancement in MEMS technology today wireless sensor network has gained a lot of importance. The wide range of its applications includes environmental and habitat monitoring, object localization, target tracking, security surveillance etc. Wireless sensor networks consist of tiny sensor devices called as motes. The constrained computation power, battery power, storage capacity and communication bandwidth of the tiny motes pose challenging problems in the design and deployment of such systems. In this paper we provide study and prototype implementation of architecture and algorithm for network of tiny wireless sensors for localization purpose.

Keywords: sensor network; localization, RSSI; Angle-of-arrival (AoA); direction-of-arrival (DoA)
