QOS Parameters based Vertical handoff Decision in Heterogeneous Network A Practical Approach

Abstract: This paper proposed the vertical handoff decision method to measure call blocking probability with respect to available number of wireless networks and analyzes the variation in mean number of request by variation in its parameter value. The multi criteria vertical handoff decision algorithm will select the best available network with optimized parameter values. For the handoff decision, the different parameters of network need to be considered based on which the handoff process will be initiated. These parameters are Network Bandwidth, RSS, threshold bandwidth, power dissipation, power consumption, network condition and these are considered as the QOS (Quality of service) as the decision will depend on these parameters and calculations. The handoff approach will handle the optimization problems of vertical handoff in heterogeneous wireless network. The proposed approach is easy to implement and has less computational complexity in terms of time.
