A self-similarity based vertical handoff algorithm for wireless heterogeneous networks
2010
In the future, the wireless communication network based on IP technology is a heterogeneous network which can integrate various wireless networks as a seamless connectivity to each other. Vertical handoff is a key technology to accomplish this target. However, little attention has been focused on the self-similarity of IP packets in vertical handoff decision algorithm. This paper proposes a self-similarity based vertical handoff algorithm for wireless heterogeneous network. In addition, the pre-decision mechanism is added. Simulation results show that this algorithm can reduce call blocking possibility (CBP) and handoff call dropping possibility (HCDP) of the system.
