Because of different system capacities of base station(BS)or access point(AP)and ununiformity oftraffic distribution in different cells,quantities of new call users may be blocked in overloaded cell incommunication hot spots.Whereas in some neighboring under-loaded cells,bandwidth may be superflu-ous because there are only few users to request services.In order to raise resource utilization of the wholeheterogeneous networks,several novel load balancing strategies are proposed,which combine the call ad-mission control policy and multi-hop routing protocol of ad-hoc network for load balancing.These loadbalancing strategies firstly make a decision whether to admit a new call or not by considering some param-eters like load index and route cost,etc.,and then transfer the denied users into neighboring under-load-ed cell with suiplus channel according to optimum multi-hop routing algorithm.Simulation results showthat the proposed load balancing strategies can distribute traffics to the whole heterogeneous wireless net-works,improve the load balance index efficiently,and avoid the call block phenomenon almost absolutely.
