AbstractThe demand for real-time applications such as short video clips of CCTVs on a roadway, raises the need of for seamless and ubiquitous Internet connectivity in vehicular networks. Wireless Access in Vehicular Environment (WAVE) architecture defines the IPv6 mobility protocols to be deployed in network layer. However, the Current IP mobility management protocols, including Proxy Mobile IPv6 (PMIPv6), employ a centralized and single anchor to register MU's location information and establish communication which causes excessive burden on that central anchor. Recently, Distributed Mobility Management (DMM) based on PMIPv6 has been introduced to overcome these problems. In this paper, we investigate the vehicle velocity effect in urban environment where a map within the city of Bangi is taken. We compare the handover performance of network-based DMM with PMIPv6 in aspects of handover latency, session recovery, packet loss and throughput. The results show that network-based DMM outperforms PMIPv6 slightly.

Design and development of network simulator module for distributed mobility management protocolbalfagih, zain; External Collaboration; Artificial Intelligence & Cyber Security Lab; Computer Science; balfagih, zain (Springer Berlin Heidelberg, 2022-07-15)Distributed Mobility Management (DMM) is presented recently by IETF to overcome the limitations of the conventional Centralized Mobility Management (CMM) protocols. It is developed based on the network-based CMM protocol; Proxy Mobile IPv6 (PMIPv6). DMM tackles the issue of relying on a single entity by decoupling the control and data planes and distributes the functionalities of the centralized entity in CMM protocols. To study and examine the performance of DMM protocol, different evaluation approaches can be utilized. Although the test-bed implementation is more realistic approach, its drawbacks, such as high cost, complexity and unscalable, make the utilization of test-bed extremely difficult. Alternatively, simulation is an inexpensive and effective approach of testing various complex scenarios with scalability features. In this context, this paper presents DMM module for Network Simulator-2 (NS-2) implementing DMM entities, functionalities and operation. The paper also evaluates the performance of DMM protocol comparing to CMM protocol in different scenarios. The analytical evaluation of handover latency and session recover time is employed to ensure validity and reliability of DMM module. The results show that the developed module is valid and reliable where the theoretical results are approximately similar to the results obtained from simulation.
Fast handover solution for network-based distributed mobility management in intelligent transportation systemsBalfaqih, Mohammed; mahamod, ismail; Rosdiadee, Nordin; Abd Alrazak, Rahem; balfagih, zain; External Collaboration; Artificial Intelligence & Cyber Security Lab; Computer Science; Balfaqih, Mohammed (Springer US, 2017-02)The current IP mobility protocols are called centralized mobility management (CMM) solutions, in which all data traffic and management signaling messages must be forwarded to an anchor entity. In some vehicle scenarios, vehicles may move as a group from one roadside unit to another (i.e., after traffic lights or traffic jams). This causes data traffic and exchanged mobility messages to peak at the anchor entity and, consequently, affects the network performance. A new design paradigm aimed at addressing the anchor entity issue is called distributed mobility management (DMM); it is an IETF proposal that is still being actively discussed by the IETF DMM working group. Nevertheless, network-based DMM is designed based on the well-known network-based CMM protocol Proxy Mobile IPv6 (PMIPv6). There is no significant difference between network-based DMM and PMIPv6 in terms of handover latency and packet loss. Because vehicles change their roadside unit frequently in this context, the IP addresses of mobile users (MUs) require fast IP handover management to configure a new IP address without disrupting ongoing sessions. Thus, this paper proposes the Fast handover for network-based DMM (FDMM) based on the Fast Handover for PMIPv6 (PFMIPv6). Several modifications to PFMIPv6 are required to adapt this protocol to DMM. This paper specifies the necessary extensions to support the scenario in which an MU has old IP flows and hence has multiple anchor entities. In addition, the analytic expressions required to evaluate and compare the handover performance of the proposed FDMM and the IETF network-based DMM have been derived. The numerical results show that FDMM outperforms the IETF network-based DMM in terms of handover latency, session recovery and packet loss at the cost of some extra signaling.
Design and evaluation of network-based distributed mobility management solution based on PFMIPv6Balfaqih, Mohammed; Ismail, M; Nordin, R; balfagih, zain; Yuwono, Tito; External Collaboration; Artificial Intelligence & Cyber Security Lab; Computer Science; Balfaqih, Mohammed (IEEE, 2016-08-01)Proxy Mobile IPv6 (PMIPv6) protocol provides IP mobility support to a Mobile User (MU) once it performs a handover from an access router to another. Furthermore, Fast Handover for PMIPv6 (PFMIPv6) protocol has been standardized to improve the handover performance of PMIPv6 in terms of handover latency and packet loss. The limitation of these Centralized Mobility Management (CMM) protocols (e.g., non optimal routes, single point of failure and scalability) has led to the development of Distributed Mobility Management (DMM) paradigm. DMM aims to flat the network architecture by placing the anchor entity dynamically closer to the MU. The DMM solutions can be classified into: host-based DMM, in which MU participates in IP mobility process, and network-based DMM, where IP mobility process is done in the network side without MU involvement. However, existing network-based DMM proposals rely on PMIPv6 protocol which experience high handover latency and packet loss. Thus, we present the design and operation of a proposed network-based DMM solution based on PFMIPv6. We have developed an analytical model to evaluate and compare the handover latency and the packet loss of the proposed network-based DMM solution and IETF networkbased DMM proposal.
