Performance Analysis of HRO-B+ Scheme for the Nested Mobile Networks using OPNet

<p>As a demand of accessing Internet is increasing dramatically, host mobility becomes insufficient to fulfill these requirements. However, to overcome this limitation, network mobility has been introduced. One of its implementation is NEMO Basic Support protocol which is proposed by Internet Engineering Task Force (IETF). In NEMO, one or more Mobile Router(s) manages the mobility of the network in a way that its nodes would be unaware of their movement. Although, it provides several advantages, it lacks many drawbacks in term of route optimization especially when multiple nested mobile networks are formed. This paper presents a new hierarchical route optimization scheme for nested mobile networks using Advanced Binding Update List (BUL+), which is called HRO-B+. From performance evaluation, it shows that this scheme performs better in terms of throughp<em>ut, delay, response time, and traffic, and achieves optimal routing.</em></p>

The PMIPv6-Based Group Binding Update for IoT Devices

Internet of Things (IoT) has been booming with rapid increase of the various wearable devices, vehicle embedded devices, and so on, and providing the effective mobility management for these IoT devices becomes a challenge due to the different application scenarios as well as the limited energy and bandwidth. Recently, lots of researchers have focused on this topic and proposed several solutions based on the combination of IoT features and traditional mobility management protocols, in which most of these schemes take the IoT devices as mobile networks and adopt the NEtwork MObility (NEMO) and its variants to provide the mobility support. However, these solutions are in face of the heavy signaling cost problem. Since IoT devices are generally combined to realize the complex functions, these devices may have similar movement behaviors. Clearly analyzing these characters and using them in the mobility management will reduce the signaling cost and improve the scalability. Motivated by this, we propose a PMIPv6-based group binding update method. In particular, we describe its group creation procedure, analyze its impact on the mobility management, and derive its reduction ratio in terms of signaling cost. The final results show that the introduction of group binding update can remarkably reduce the signaling cost.

Alleviation of Binding Update Re-registration Handoff Latency at Home Agent Failure in MIPv6 Network

Home Agent (HA) is an indispensable entity for binding connectivity to route packets between Mobile Node (MN) and Correspondent Node (CN). MIPv6 allows the deployment of redundant HAs to overcome HA failure. Different approaches resolve this issue to recuperate binding association information. This paper compares the effect of handoff latency in various methods and proposes a Reliable HA delivery (RHAD) mechanism to mitigate the Binding Update (BU) registration latency in HA at the time of active HA failure. We use BGP domain in network architecture and apply IBGP protocol to transmit packets between Edge Router (ER) and HA. Both the theoretical evaluation and simulation results reveal that RHAD effectively reduces BU re-registration handoff latency and increases packet delivery ratio.
