Overview of Mobile IP Handoff Scenario for Mobile IP Quality-of-service in Mobile IP Mobile IPv6 Quality-of-service in Mobile IPv6

OVERVIEW OF MOBILE IP

ISSUES IN MOBILE IP

Moving from one subnet to another is Handoff.

There is packet loss and delay during mobile host’s handover from one subnet to another.

Tunneled Traffic Received (bits/sec) Total amount of traffic that was decapsulated by FA’s and MR’s

Tunneled Traffic Sent (bits/sec) Total amount of traffic that was encapsulated by HA’s.

GLOBAL STATISTICS

QUALITY-OF-SERVICE IN MOBILE IP

QUALITY-OF-SERVICE PARAMETERS

SCENARIO FOR MOBILE IPV6

QUALITY-OF-SERVICE PARAMETERS – MIPV6

COMPARISON BETWEEN MIPV4 & MIPV6

Conclusion

Built a scenario in opnet modeler to simulate handover in Mobile IP

During handover in mobile networks there is packet loss due to handover issues.

Mobile IPv6 performs better than Mobile IPv4 in terms of delay, throughput, packet drop, etc.
