A Graph Theory Based Network Selection Algorithm In Heterogeneous Wireless Networks

The major trend in heterogeneous wireless networks is determining the best access network for the end user in terms of quality of service (QoS) and providing ubiquitous connectivity during the network selection transition. In this paper, we propose a new mechanism based on graph theory for the selection of the best path for network selection decision. We carry out experiments evaluation on a testbed by using mininet, to demonstrate the efficacy of our proposed mechanism as compared to conventional network selection algorithms. Our experimental results show that our proposed mechanism can achieve a significant performance in terms of QoS metrics for two services FTP and video streaming.
