    • PROBLEM STATEMENT • The Internet network architecture and its protocols are not suitable to support the emerging demand on dynamic mobility. • Centralized mobility approaches have problems and limitations, such as: – – – – Non-optimal routes Scalability Network bottlenecks Single point of failure and attack Distributed Mobility in Dynamic Environments 4
    • SOLUTIONS BASED ON THE NETWORK LAYER • MIPv6 Distributed Mobility in Dynamic Environments 5
    • SOLUTIONS BASED ON THE NETWORK LAYER • DMIPA (Dynamic Mobile IP Anchoring) Distributed Mobility in Dynamic Environments 6
    • OBJECTIVES • Evaluation of MIPv6 and DMIPA performance in vehicular and dynamic environment • Design and development of a network topology and vehicular scenarios Tasks: - Development of a main C++ program (NS-3) - Development of vehicular scenarios (SUMO) - Testing and getting results Distributed Mobility in Dynamic Environments 7
    • EVALUATE MIPV6 AND DMIPA PERFORMANCE IN VEHICULAR SCENARIOS • Network Topology Core Network - 100 Mbps point-to-point data link - 1 milisec channel delay GW1 to HA - 100 Mbps point-to-point data link - 2 milisec channel delay GW1 to CN1 and CN2 - 100 Mbps point-to-point data link - 10 milisec channel delay GW2 to CN3 and CN4 - 100 Mbps point-to-point data link - 40 milisec channel delay Distributed Mobility in Dynamic Environments 8
    • EVALUATE MIPV6 AND DMIPA PERFORMANCE IN VEHICULAR SCENARIOS • Deployed Scenarios a) c) b) Distributed Mobility in Dynamic Environments 9
    • EVALUATE MIPV6 AND DMIPA: PARAMETERS Parameters • Signalling Cost • Data Loss • Average Data Delay • Average Binding Update Distributed Mobility in Dynamic Environments 10
    • EVALUATE MIPV6 AND DMIPA: RESULTS AND ANALYSIS Results – deployed scenario of Figure 8 a) Distributed Mobility in Dynamic Environments 11
    • EVALUATE MIPV6 AND DMIPA: RESULTS AND ANALYSIS Results – deployed scenario of Figure 8 b) Distributed Mobility in Dynamic Environments 12
    • EVALUATE MIPV6 AND DMIPA: RESULTS AND ANALYSIS Results – deployed scenario of Figure 8 c) Distributed Mobility in Dynamic Environments 13
    • CONCLUSIONS • DMIPA is a better solution than MIPv6 in vehicular environments. • Using the same number of DMARs and ARs, DMIPA is able to provide better results. Distributed Mobility in Dynamic Environments 14
    • MULTIHOMING CONCEPT • Multihoming: a node that has several network interfaces connected to various access networks. Use-case of a multihoming scenario Distributed Mobility in Dynamic Environments 15
    • GOALS OF MULTIHOMING • • • • • • Ubiquitous Access; Redundancy/Fault-Recovery; Load Sharing Load Balacing; Bi-casting; Preference Settings. Distributed Mobility in Dynamic Environments 16
    • OBJECTIVES • Proof of concept: DMIPA with and multihoming support in a real testbed without • Design and development of real scenarios to validate on the testbed Tasks: - Deployment of DMIPA in the real testbed - Configuration of UDP and TCP sessions - Configuration of PTPd to sync the clock of all network elements NAP - Vehicular Networks 17
    • DEPLOYED USE-CASE SCENARIOS Scenario A Scenario B Scenario C Scenario D Use-case scenarios without multihoming support (left) and with multihoming support (right) NAP - Vehicular Networks 18
    • TESTBED DESCRIPTION CN: D-ITG and PTPd application ARs: Configuration of DMIPA protocol MN: D-ITG and PTPd application and configuration of DMIPA protocol Distributed Mobility in Dynamic Environments 19
    • EVALUATION AND RESULTS Bitrate and End-to-end Packet Delay of TCP Sessions (Scenario A) Distributed Mobility in Dynamic Environments Bitrate and End-to-end Packet Delay of TCP Sessions (Scenario B) 20
    • EVALUATION AND RESULTS Bitrate and End-to-end Packet Delay of TCP Sessions (Scenario C) Distributed Mobility in Dynamic Environments Bitrate and End-to-end Packet Delay of TCP Sessions (Scenario D) 21
    • CONCLUSIONS • The results indicate that user experience is improved when DMIPA takes advantage of multihomed mechanism. • In some of the cases, it is possible to observe a decrease of the delay value. • Multihoming can ensure session continuity if down link event occurs. Distributed Mobility in Dynamic Environments 22
    • FINAL CONCLUSIONS • DMIPA improves the mobility management overall performance when compared with MIPv6. We will opt for DMIPA to deploy a mobility management protocol in vehicular environments. • DMIPA with multihoming support provides session continuity while reduces the network cost and improve the user experience Distributed Mobility in Dynamic Environments 23
    • FUTURE WORK • Evaluate DMIPA in a real vehicular environments: a) implement DMIPA on the available testbed; b) measure the performance in laboratory; c) test DMIPA in a real and dynamic vehicular scenario. • Improve the DMIPA with multihoming support: a) optimize the handover mechanism; b) create a high level mechanism that manages the procedures in multihoming scenarios.
