Obstacle discovery and localization scheme for wireless sensor network

This paper reports an obstacle discovery and localization scheme in wireless sensor network (ODLS). Sometime due to limited knowledge about obstacle, source node´s data are unable to reach destination node. Therefore, base station unaware about the source node´s monitoring field. On the other hand, without the knowledge of obstacles end-user is unable to make appropriate decisions. The propose scheme detects obstacle having minimum exposure with graph based triangulation scheme and also detects approximate location of it by edge based scheme. Experimental results show that the proposed scheme ensures better obstacle detection and localization in wireless sensor network.
