Cost-aware multihop handover in multihop radio access network

This paper proposes cost-aware multihop handover in multihop radio access network, where multihop handover is performed based on a cost function, which is a weighted sum of hop count and the inverse of minimum available bandwidth. Then the performance of the proposed handover is analyzed via NS-2 simulation. Simulation result shows that there is tradeoff between the previous handovers and the proposed handover for varying traffic load, and the proposed handover outperforms the previous handovers as traffic load increases.
