Abstract

We propose a novel scheme for tracking the mobility of users in a wireless ad hoc network. Mobile nodes track their positions using pilot signal strengths from neighboring nodes within a local coordinate system based on relative distances between nodes. Node mobility is modeled as a linear system driven by a discrete command semi-Markov process. Mobility tracking is performed using an extended Kalman filter preceded by an averaging filter. Our numerical results show that the mobility tracking scheme performs effectively and can be used to enhance routing performance in ad hoc networks.
