NIA based Mobility Management Technique for Seamless Roaming in Heterogeneous Networks
Sivakami Thiyagarajan,Shanmugavel Sedhu 보안공학연구지원센터 2014 International Journal of Future Generation Communi Vol.7 No.6
Heterogeneous networks are composed of different access technology together to provide Always Best Connected services in anywhere at any time. In such environment mobility is the major issue. Existing mobility support protocols like MIPv6, HMIPv6 and FMIPv6 are performing low during vertical handoff process. To improve QoS performances and to interconnect different networks, an agent called NIA (network interworking agent) and multiple IGMA (interworking gateway mobility agent) has been deployed. The UDP and TCP simulation results are obtained using NS2 environment and compared with an existing macro mobility protocols.
