Target Tracking Problem in Mobile Sensor Networks
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 9
Abstract
Target Tracking became a challenging task for the researchers in sensor networks, where it dictates the accuracy of a targets position and is measured. This paper discussed the target tracking problem in a mobile sensor network (MSN), where it is assumed that mobility can be broken to improve the tracking resolution. This problem becomes challenging as the mobility and trajectories of both sensors and targets are to be captured. It is derived the inherent relationship between the tracking resolution and a set of crucial system parameters including sensor density, sensing range, sensor and target mobility. Investigation is made for the correlations and sensitivity from a set of system parameters and derived the minimum number of mobile sensors that are required to maintain the resolution for target tracking in an MSN. The simulation results show that the tracking performance can be improved by an order of magnitude with the same number of sensors when compared with that of the static sensor environment.
