This paper mainly focuses to reduce the localization error of a sensor node which is deployed in a WirelessSensorNetwork (WSN). Here, time-of-arrival (TOA) and angle-of-arrival (AOA) based random transmission directedlocalization (RTDL) technique is considered. This technique can be applied in wireless sensor networks, especiallysuitable for network with low frequency range in the wireless sensor network. In this work, localization Error could beimproved via TOA–AOA during node communicating with each other.Ad hoc On-Demand Distance Vector (AODV)routing protocol to be implemented in this work.The nodecategories in two ways: those nodes equipped with knownvector position of the Omni-direction antenna (Source-nodes) and those nodes equipped with unknown vector position ofthe Omni-direction antenna (Sink-nodes). All nodes are capable of communicating with other nodes. Source-nodes arecapable of positioning (TOA–AOA estimation) the other nodes located in their coverage area. The system estimates theerror rate of distance between the nodes, by measuring TOA–AOA based RTDL at an appropriate number of nodes. Thispaper shows the proficiency of the proposed method to reduce the localization error and determine the attacker’s nearestlocation in the network.
