AN ANALYSIS OF MOBILITY AND SEAMLESS HANDOFF MANAGEMENT AND PROPOSING A NEW ALGORITHM TO IMPROVE DELAY PERFORMANCE

Computer Engineering

In this paper we are presenting an analysis of mobility and seamless handoff management and proposing a new algorithm to improve delay performance. A heterogeneous wireless network (HWN) which is hybrid network of cellular network (having access routers (AR) and Internet Service Providers (ISP) for providing communication and internet services to the VANET) and VANET. Internet Engineering Task force (IETF) purposed MIPv4/v6 (Mobile Internet Protocol -version4/6) and FMIPv6 (Fast) as mobility and handover management techniques which are standard protocols. An enhancement of FMIPv6, a handover management technique using concept of tunnelling is simulated in a VANET scenario. NS2 is the simulating tool for analysing performance of advanced FMIPv6 against standard FMIPv6 by considering the parameters like Tunnelling Performance, Handover Latency, Packet Loss, Signalling Overhead Ratio, Service Disruption Time, and Network Time.
