Centralized Media Independent Soft Handover Decision (CMISHD) for Multi-Interface Mobile Node in 4G Heterogeneous Wireless Networks

Authors : P. Vetrivelan and P. Narayanasamy

Abstract: The next generation mobile communication system called as 4G/NGWN is expected to include heterogeneous wireless networks that will offer high data rate multimedia services to end users at lowest cost. In present Wireless Systems the capability of broader coverage is available but has the limitation of bandwidth and network cost. In addition to the coverage, need to ensure the higher quality of content-delivery at lower cost. This study proposes Centralized Media Independent Soft Handover Decision (CMISHD) which uses Nash-equilibrium based handover for quality oriented content delivery. The primary idea is based upon SASHA which is a Smooth Adaptive Soft Handover Algorithm for wireless networks. The study predominantly focuses on optimizing the ideas that were proposed by SASHA. Simulation based testing for data/video traffic transmissions are presented, depicting the performance of CMISHD in various complex scenarios involving large number of mobile nodes, activities like node movement-velocity have also been simulated which is not addressed in SASHA. The results also show how CMISHD scheme can take content delivery, a step ahead, by its quality calculations and considerations which were optimized from SASHA.
