Optimizing soft handoff latency and access network selection for next generation mobile communication networks

Soft Handoff Evaluation and Efficient Access Network Selection in Next Generation Cellular Systems

“…The alternative access network is the one with the highest value of relative closeness to ideal solution. We also compare the access network selection results of SEA techniqueobtained in [5] with TOPSIS, to evaluate the efficiency of both selection techniques, in selecting the best access network for handoff.…”

“…The system framework is shown in Figure 1. To ensure effective comparison between SEA and TOPSIS, the most promising values generated from the membership functions of the triangular fuzzy numbers in the fuzzy-AHP method in [5] were used to construct the AHP pair-wise comparison matrix for the considered criteria necessary for handoff decision. The AHP process in the end assigns weights to criteria which are used by the TOPSIS method to perform final ranking of the access networks.…”

“…Our focus is on the handoff decision phase and aimed at satisfying mobile subscriber through the ABC concept. Further, the performance of TOPSIS in network ranking is compared with the synthetic extent analysis using decision criteria values obtained in [5]. This paper is structured as follows: A critical review of literature on related works is done in section 2; Section 3 presents the materials and methods required for accomplishing the study; Section 4 discusses the results obtained; and Section 5 offers conclusion to the study.…”

“…The current work is an extension of our FTC'16 paper [5]. First, we subject the available (handoff) input data to two machine learning procedures: (i) unsupervised analysis of inherent patterns; and (ii) supervised classification of the system performance.…”

“…A QoS mechanism was proposed in [5] for improved handoff decisions in mobile communication networks. The proposed design adopted a hybrid channel perception tool to train observed key performance channel characteristics for system channel behaviour discovery.…”
