Agenda
Next generation networks are envisioned to be heterogeneous in nature as the demands are increasing towards the ubiquitous services in wireless networks. As different networks are having widely varying characteristics, it is difficult to maintain the QoS (Quality of Service) after handoff from one network to another network. Maintaining the QoS, based on applications, during the handoff in heterogeneous wireless networks needs an intelligent handoff decision mechanism. This lecture will focus on a QoS aware fuzzy rule based vertical handoff mechanism that makes a multi-criteria based decision, found to be effective for meeting the requirements of different applications in a heterogeneous environment. The QoS parameters considered are: available bandwidth, end-to-end delay, jitter, and bit error rate (BER). A new evaluation model is proposed using a non birth–death Markov chain, in which the states correspond to the available networks. Simulation results show that compared to other vertical handoff algorithms, the proposed algorithm gives better performance for different traffic classes. This work also explains the proof of concept of vertical handover demonstration using the proposed QoS aware vertical handover algorithm. The experiments were conducted in MobileIP testbed at IISc, Bangalore. The experiments were carried for both 3G to WiFi and WiFi to 3G scenarios. Real time streaming application is tested with the QoS aware fuzzy rule based algorithm.
