Exploring a New Proactive Algorithm for Resource Management and Its Application to Wireless Mobile Environments

Abstract

In order to provide ubiquitous communication, seamless connectivity is now required in all environments including highly mobile networks. By using vertical handover techniques, it is possible to provide uninterrupted communication as connections are dynamically switched between wireless networks as users move around. However, in a highly mobile environment, traditional reactive approaches to handover have been found to be inadequate. Therefore, the proactive handover techniques are actively being investigated in the context of next generation mobile networks. This paper presents a new methodology to support proactive resource allocation for emerging future networks such as 5G by allowing base stations to calculate the probability of contention based on the demand for network resources. The proposed approach uses Markov chains to model the contention and results are obtained showing enhanced system performance in terms of throughput and mean response time.
