In wireless heterogeneous network, nodes are mobile equipment and can move freely from one area to another. A group of users with a large range of mobility can access around in the overall network cause high traffic. In these heterogeneous networks, resources are shared among all users and the amount of available resources is determined by traffic load. The traffic load can seriously affect on quality of services for users thus it requires efficient management in order to improve service quality. If traffic load is concentrated in a cell, this cell becomes the hotspot cell. There is a need to have a proper traffic driven handoff management scheme, so that users will automatically move from congested cell to allow the network to dynamically self-balance.
