“…The solution presented in [24] assumes that multiple HAs, called as "Home Agents Group" (HA Group), can work concurrently to overcome the difficulty of HA as the only failure point. All the mobility management tasks are handled by the main HA and are taken over by stand-by HA when the main HA fails.…”

Mobile IPv6 came as an extensively acknowledged technology to support mobility in networks. Home agents are in charge for the registration of mobile devices and act as a key entity for the tunneling of data packets to the corresponding registered mobile nodes. A single home agent has administrative control over the critical tasks including home agent registration management, maintenance of cache data and tunneling of data packets to the mobile nodes that are away from their home networks and so on. However in this approach, home agent act as the sole failure point, which gave rise to the placement of multiple home agents to overcome this issue. The load balancing mechanism for multiple home agent deployment faces the problem of improper load sharing, signaling overhead and synchronization issues. Moreover, failure detection and recovery mechanism are inefficient in nature. It experiences a significant delay in tunneling of data packets and suffers from disconnection making it incompetent for the use in real time applications. Most of the existing methods for load sharing and failure detection use the concept of exchange of router advertisement message named as "heart beat messages" at a constant rate. The reduction in the interval of router advertisement can result in signaling overhead and synchronization issues. Hence, this paper investigates and analyzes the various load balancing mechanisms of mobile IPv6. In addition, it presents the comparative study of the failure detection and recovery mechanism of existing methods. Finally, it concludes that future work can be extended in the domain of distributed active load sharing mechanism and proactive failure detection.

“…Each mobile host is assigned a home address when it is present inside the home network. When the mobile host moves out of the home network, it is identified by the Care of Address (CoA) which is registered with the home agent (Abdelgadir et al, 2011). Mobile IP specifies the procedure of how a mobile node registers its CoA with the home agent and how the home agent routes the packets to the mobile node (Beijnum, 2006).…”

Problem statement:In recent times, wireless networks have become ubiquitous and the hotspot research arena. When a mobile node switches from one access network to another network, the node is said to perform a handoff. This transition is a complex and time-consuming task since after transit the mobile node has to obtain a new Care of Address (CoA) from the transited AR and bind this CoA with its home agent, apart from this there occurs a problem of packet loss. However there exist some solutions for this handoff problem, these mechanisms do not offer efficient solution for the problem. Approach: A mechanism to reduce the hand off delay in vehicular networks is proposed in this article. This approach pre allocates the new address for the mobile node before hand off based on its mobility. Results: The proposed system is implemented in ns2 simulation environment and compared with some existing hand of mechanisms and its evident that the proposed mechanism reduces the hand off delay and packet loss ratio. Conclusion: This article is concerned with defining a better solution for the handoff problem such that the proposed mechanism offers efficient results compared to the existing system.

SUMMARY Home agent is a key component of MIPv6 functionality that comprises binding cache to hold the mobile nodes current point of attachment to the Internet. This paper is concerned with binding cache support for home agents within MIPv6 network. Existing binding cache of home agent supports weak cache consistency by using fixed contract length for Binding Refresh Request, which functions reasonably well in normal situations. However, maintaining a strong binding cache consistency in home agent as a crucial exceptional handling mechanism has become more demanding for the following objectives: (i) to adapt increasingly frequent change of care‐of address due to mobile nodes movement detection update; (ii) to provide fine‐grain controls to balance the binding cache load distributions for better delivery services; and (iii) to reduce the overhead allowances around the binding cache. In this paper, we have first verified the effectiveness of Binding Refresh Request contract length, and on the basis of that, two dynamic contract algorithms are suggested to reduce the storage and communication overhead allowances in binding cache. We have also compared our technique with the existing fixed Binding Refresh Request contract length, and our simulation results reveals that the proposed approach provides an effective performance to reduce overhead within the network.
