Approach to perform horizontal and vertical handoff in wireless network

Multiple wireless access network combine together to form wireless communication system. Making handoff decision is critical task in wireless networks and it increases day by day with increase the number of mobile devices which is interface with the network. In this scheme we are going to propose the seamless approach to perform vertical and horizontal handoff. This scheme will reduce the probability of call blocking and dropping during the handoff process. This also helps to reduce the unnecessary handoff in networks.
