Interface Selection for Multihomed Mobile Hosts

In this paper we discuss the problem related to interface selection in a multihomed mobile host. Traditional signal strength or priority based handover algorithms may not be sufficient for providing an always-best-connected access for the user in a heterogeneous multi-access environment. We present the policy based handover logic of VERHO mobility management system, where handover decisions are made in a more intelligent way with several affecting cross-layer parameters, policies and interface selection algorithms. Mainly, in this paper, we concentrate on comparing and analyzing different interface selection algorithms in Matlab simulations to find out the best alternative for the VERHO system
