Research of load balancing in heterogeneous wireless network

This paper proposed a joint optimization model for bandwidth allocation and network load balancing,it utilized the bandwidth of users to establish network utility and cost functions under the constraints,through the association matrix the model could get the scheme of bandwidth making heterogeneous wireless networks balanced.The simulations demonstrate the result of joint optimization model is distributed among the proposed cost functions and the network utility;it also can optimize the allocation of bandwidth to achieve load balancing of networks.
