Performance of an Adaptive Timer-based Handoff Scheme for Wireless Mobile Communications

摘要

In this paper, an adaptive timer handoff (ATHO) algorithm is proposed for mobile cellular communication systems. The proposed ATHO algorithm scheme is based on received signal strength (RSS) with a hysteresis timer to adapting the ping-pong effect for mobile systems. Moreover, the ATHO algorithm outperforms the fixed timer handoff (FTHO) algorithm in link quality of service for mobile systems. We proposed a performance index with weighted based handoff rate and handoff delay. With the performance index, we optimize the handoff adaptivity for proposed ATHO. Simulation results show that he proposed ATHO can adapt the fast MS and out perform the FTHO algorithm, especially for the driving mobile stations (MSs).
