A major challenge of the heterogeneous wireless networks is how to jointly utilize the resources of different radio access technologies in an efficient manner. Because of the different system capacities of BS/AP and ununiformity of traffic distribution in different cells, quantities of new calls may be blocked in the overloaded cell in some hot spots; whereas its neighboring under-loaded BS/AP have superfluous bandwidth. In order to raise resource utilization of heterogeneous networks, several novel load balancing strategies are proposed, which combine the call admission control and multi-hop routing protocol of ad-hoc network.
