Abstract—In this paper we have introduced an algorithm for localization in wireless sensor network (WSN) with the help of directional antenna. Location of each node in a wireless sensor network play an important role after tracing or event detection on a particular node. Manually configuration of location about each node in wireless sensor environment is not feasible at the time of deployment. Our localization algorithm is based on the directional antenna, every node in sensor network is configured with directional antenna and few sensor nodes have GPS receiver are called anchor node. Anchor node helps to other normal nodes to localize them. Software has been developed for localization using C language which will works in two phases: first one Query the sensor network and collect information about neighbours, distance and angle. Give this information as input to the software and the location of every node will be calculated. And second one is, compile the software for sensor nodes. Install the software in sensor nodes and the sensor nodes will calculate their location.
