Description This paper presents an efficient technique in the reduction of frequent handover for macro-femto cells in Long Term Evolution (LTE) networks. A key design feature for handover decision algorithms is to guarantee seamless handover process between wireless access technologies without degrading the Quality of Service (QoS) and Quality of Experience (QoE) of the users. There are unwanted scenarios in vertical handover schemes where due to poor handover process, frequent handovers occur resulting in wastage of network resources, handover failures, and subsequent dissatisfaction of the users. Despite a number of efforts made to mitigate this problem of poor handover, network users still experience significant degradation in call quality owing to the dissimilarities in access technologies available and the changing speed of the user. A handover decision algorithm, which is based on the user’s changing speed and network connection time, was proposed in this work and it involves the incorporation of a dwell time into a proximity model prediction technique in order to make the handover decision better. Results obtained using MATLAB R2015b version showed that the proposed algorithm attained a 77.46% reduction in the number of unnecessary handover.
