Abstract

Abstract:

In order to improve the accuracy of vertical handover and to reduce the “Ping-Pong effect”, a difference threshold based fuzzy handover (DTFH) algorithm is proposed for heterogeneous networks. The handover trigger and handover decision are considered for DTFH. The signal to noise ratio (SNR) gap between the target network and the current network is obtained by the mobile station (MS), and the SNR gap between the two networks is compared with a predefined trigger threshold for handover trigger. Then based on the method of fuzzy logic, the MS gets the fuzzy decision values of the target network and the current network, and the gap between the fuzzy decision values of these two networks is compared with a predefined decision threshold for handover decision. In simulation, a heterogeneous network comprising LTE and WiMAX is used. Compared with traditional handover algorithms, the simulation results show that the DTFH algorithm can reduce the “Ping-Pong effect”, increase the throughput of MS, and improve the performance of vertical handover.
