Policy based admission control and handoff decision algorithm for next generation All-IP wireless network

The present work is a policy based admission control algorithm and handoff decision algorithm for next generation all-IP wireless network. It uses policy based admission control algorithm to admit a new call and policy based handoff decision algorithm to admit a handoff call. The proposed scheme also uses the network initiated vertical handoff algorithm to perform load balancing, to maximize battery power life time of a mobile node, to minimize power consumption, system delay and loss of packet, and finally to maximize the throughput of the network. Results based on a detailed performance evaluation study are also presented to demonstrate the efficacy of the proposed scheme.
