OUTLINE
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.
Quality-of -Service
HANDOFF
MOBILE IP SCENARIO
ATTRIBUTES – HOME AGENT
FOREIGN AGENT
CORRESPONDING NODE
MOBILE NODE
TRAFFIC SENT AND RECEIVED IN CORRESPONDING NODE
TRAFFIC SENT / RECEIVED FROM HOME AGENT AND FOREIGN AGENT
GLOBAL STATISTICS
IRDP Traffic Sent(bits) Amount of traffic from agent advertisements .
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
NODE STATISTICS IRDP Traffic Received (bits) Amount of agent
advertisement traffic received by MN/Routers. IRDP Traffic Sent (bits) Amount of agent
solicitation traffic generated by mobile MN/ Routers.
Size of Binding table No. of entries in HA binding table
Size of Visitor List No. of entries in FA visitor list
Tunneled Traffic Received(bits/sec) Amount of traffic that was decapsulated by FA/MR
Tunneled Traffic Sent (bits/sec) Amount of traffic that was encapsulated by FA
NODE STATISTICS – FOREIGN AGENT 1
NODE STATISTICS – FOREIGN AGENT 2
NODE STATISTICS – HOME AGENT

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.
