Wireless Node Localization for V-Shaped and Rectangular-Shaped Node Deployment Schemes
The positioning of wireless nodes in indoor Wireless Local Area Network (WLAN) using Received Signal Strength Indication (RSSI) has become an attractive low cost localization solution. The location accuracy of RSSI based algorithms is dependent on node placement topology. The localization performance analysis reported for nodes arranged in V-shaped linear configuration. The uniqueness of this paper ensures comparative study of localization performance in Vboundary array and its counterpart regular rectangular boundary node layout. The localization performance is computed in terms of Cramer - Rao Lower Bound (CRLB) of range estimate under dynamic indoor environments.
