TAR: TOA-AOA Based Random Transmission Directed Localization

This paper presents time-of-arrival (TOA) and angle-of-arrival (AOA) based random transmission directed localization (RTDL) technique. This technique can be applied in ad hoc networks, especially suitable for network with low frequency range in the wireless network. In this work, localization Error during node communication in wireless network would be optimized via TOA-AOA across multiple nodes and can focus on estimating the attackers' physical location in the network. In the proposed method using Ad hoc Mobile Distance Vector (AOMDV), we assume two categories of nodes: those equipped with known vector position of the omni-direction antenna (base-nodes) and those equipped with unknown vector position of the omni-direction antenna (target-nodes). All nodes are capable of communicating with other nodes. Base-nodes are capable of positioning (TOA-AOA estimation) the other nodes located in their coverage area. The system estimates the error rate of distance between the nodes, by measuring TOA-AOA based RTDL at an appropriate number of nodes. In the proposed system, we determine the Reliable Shortest Routing in Ad Hoc On-Demand Multipath Distance Vector Routing Protocol (AOMDV). This paper depicts the capability of the proposed method to considerably reduce the localization error and effectively determine the attacker's nearest location in the network.
