Network Selection Algorithm for Vertical Handover in Co-operative Wireless Network
Wireless networks are emerging towards a heterogeneous co-operative architecture to support communication needs of the end user. In this paper a centralized spectrum manager is presented which calculates the traffic load on each network and allocates another network to the user by using the network selection algorithm. Simulation results shows that the centralized spectrum manager handover the end user to another network seamlessly and improve the global spectrum efficiency. The success of wireless and mobile communications has resulted in the creation of a large variety of wireless technologics, including Second- and Third-Generation (2G and 3G) cellular, satellite, Wi-Fi, and Bluetooth.
