Application Centric Mobility Framework for Next Generation Networks

The recent paradigm of Internet of Things will play a significant role in the field of e-health, enhanced learning and assisted living where converged networks will be the prime contributing factor. With the introduction of promising paradigm of convergence of existing networks, mobile users can easily move across varied networks supported by terminals with multi interface providing real time/non real time services. The handover process leads to delay which further degrades the performance of data transmission. Vertical handover decision strategy has been proposed using Media Independent Handover IEEE 802.21 standard. The proposed algorithm is application centric and provides required level of Quality of Service for on-going application. On the basis of application type, switching from one Radio Access Technology to the other is decided. The proposed FCTS algorithm yields better result in terms of latency, throughput, delay and packet loss, avoiding frequent handovers.
