Abstract

Target tracking is one of the key applications of Wireless Sensor Networks (WSNs) that forms basis for numerous other applications. Real situations in tracking, such as an unexpected change in the mobile event's direction, failure of event detection, or transmission failure of an error message may result into erroneous tracking information. Thus, in order to prevent and handle errors effectively, it is required that tracking algorithm must incorporate error avoidance and error correction phase. In this paper we present Dead Reckoning (DR) based target tracking protocol. DR determines target's present position by projecting its past positions and speed over elapsed time and known target's path. Moreover, it inherits the functionality of error correction and error avoidance using a position fix technique. The performance of DR based tracking is also discussed, which confirms the efficacy of the algorithm.
