Vertical Handover Facilitation through Queuing Model in Heterogeneous Wireless Network

Finding a versatile performance analysis model makes a way for anytime anywhere wireless access in heterogeneous network. The major challenges of handover failure during vertical handover process necessitates careful analysis of handover calls arriving to the candidate network. The motivation is to utilize the tandem queuing model for wireless next generation network and facilitate zero level failure of vertical handover calls in interoperable network environment. The investigation gives smart schemes for service probability of handover calls to reduce the waiting time in queue. This efficient model enables the optimal attempt for handover decisions through proposed iterative algorithm to derive arrival rate. The simulation results brings performance analysis of Tandem queuing models with different queue size and the analysis proved achievement of low handover failure rate. Hence, this model can also be accommodated in vertical handover strategies for next generation network.
