The variation of signal strength caused by shadowing is a random process, and handover decision mechanisms based on measurements of signal strength induce the "ping-pong effect". The paper proposes an improved handover algorithm, which identifies the correlation among shadowing components based on an estimation of mobile velocity, to suppress the ping-pong effect. The impact of velocity estimation errors on handover performance is investigated. Simulation results indicate that the proposed approach can reduce the number of unnecessary handovers by 9-17% compared to the conventional method, while the signal outage probability remains similar.
