In the next generation wireless network each mobile node will be equipped with multiple network interfaces to utilize multiple wireless access technologies simultaneously. Such mobile nodes are multihomed mobile nodes. The seamless mobility management to provide uninterrupted connectivity to the multihomed mobile node and the dynamic resource management to reduce packet loss corresponding to the ongoing sessions of the multihomed mobile node are the challenging issues for such a heterogeneous wireless networks environment. In the present work each multihomed mobile node has multiple care of addresses corresponding to multiple network interfaces associated with it. A network analysis module is associated with each access network to determine its performance. The mobility management module provides the uninterrupted connectivity to the multihomed mobile node. The session admission control module controls the admission of sessions at various networks depending up on their performance after receiving the network selection request message from multihomed mobile node. The performance of the proposed scheme is evaluated in terms of the percentage of network usage, percentage of resource utilization per network, blocking probability and throughput of the system, bandwidth management.
