Adaptive approach for locally optimized IP handoffs across heterogeneous wireless networks

Seamless IP handoff is a crucial requirement to support real-time applications in mobile networks. In this paper, we aim to achieve seamless IP handoffs that are optimized for low latency and low packet loss in heterogeneous mobile wireless networks. We propose adaptive mechanisms that are distributed among heterogeneous network elements and mobile nodes. Adaptive process runs among geographically adjacent heterogeneous network elements and mobile nodes in the vicinity. The proposed mechanisms are devised to optimize IP handoff performances by attempting adaptive adjustment based on the local properties extracted through statistical processing.
