Emerging wireless communication technology focuses the development to provide the communication support for mobile devices based on the user demand and network connectivity for high-speed data transfer like multimedia, video and Voice over IP (VoIP). In wireless network the main issue to be addressed is channel allocation and network connectivity. Because of the limited bandwidth resources, it is necessary to provide an efficient solution for bandwidth allocation to increase number of users. Maintaining the network connectivity improves the user satisfaction. Because of the mobility of user and continuous changes in network characteristics like bandwidth, error rate, delay and jitter assigning the 'Best' network channel is a challenging issue. Handover process has been done to maintain the connectivity.
