Vertical handoff based on QOS Parameters in Heterogeneous Network

Abstract: This paper is about the study of vertical handoff algorithm and the different parameters of network based on which the decision will be considered. The method has been proposed for reduce the number of handoff and the efficient decision making for switching to other network. The handoff approach can handle the optimization problems of vertical handoff in heterogeneous wireless network. Handoff is done fast and its delay is as less as possible. Number of handoff can be minimized by proposed approach which avoids degradation in signal quality and additional loads of the network as well as Handoff latency during handoff will be minimized. Handoff algorithm is simple and has less computational complexity in terms of time. The number of nodes is present in the mobile communication. Initially, the number of network parameters has been considered and decision will depend on QOS parameters such as Network Bandwidth, RSS, threshold bandwidth, power dissipation, power consumption, network condition. This paper provides the new way of handoff decision method.
