Abstract

The base station will initiate handoff blindly and cause high failure rate of handoff if the knowledge of the terminal,s motion trend is absent. An optimized algorithm is proposed to optmize existing vertical handoff algorithm in the LTE-WiMAX heterogeneous wireless network system. The proposed algorithm uses the motion trend quantification to estimate goal cells and restrict unnecessary handoff so as to increase success rate of handoff. The computer simulation results in fading channel show that the optimized algorithm can reduce the failure rate of handoff during the handoff process and enhance the handoff performance of network.
