Agent based bandwidth estimation in heterogeneous wireless networks

Next generation mobiles in 4G wireless network have provision to access the radio resource of heterogeneous wireless networks. Further the ongoing call can be switched to another wireless network on occurrence of congestion or mobility. This technique of transferring ongoing call to another wireless network defined as vertical handoff. Before initiating vertical handoff it is necessary to estimate the available bandwidth in heterogeneous neighbouring networks. This paper addresses the agent based bandwidth estimation in 4G wireless networks. The agents together find an optimal available bandwidth for connectionless and connection oriented service. The model uses both the static and mobile intelligent agent.
