Algorithm for handover decision based on TOPSIS

Abstract

Globally, there has been a big leap in the use of smart phones which are equipped to provide access to multiple interfaces as required in Next Generation Networks. Next Generation Networks are heterogeneous in nature, supporting various radio access technologies. In such a scenario, efficient Vertical Handover becomes a necessity to provide Ubiquitous connectivity, transparent to the user and the running applications. In this paper, we have presented VHDA based on Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS). The input parameters to VHDA are RSS, bandwidth, latency, jitter, packet loss and network coverage.
