One of the most important challenge in the mobility management protocols is maintaining the MN's IP connectivity and its accessibility during its movement. Although mobility protocols have come a long way in solving this issue in IP-WSNs, they still suffer from system performance degradation during the handoff process (e.g., long handover time and heavy signaling), which is not allowable specially in the real-time applications. In this article, Enhanced Mobility Cluster Sensor Proxy Mobile IPv6 (EM-CSPMIPv6) scheme is proposed to solve these issues via keeping the MN reachable while minimizing the time of inaccessible network. EM-CSPMIPv6 introduces a fast handover scheme through applying two mechanisms. In the NON-Remote clustering (CN-MN) mechanism, this done through clustering the MNs that are moving as a group to register them in advance before their actual handoff. In the Remote-based Clustering (CR-MN) mechanism, we suggest to simultaneously manipulate mobility-related signaling of the MNs arriving to the target Access Rout (AR) at the same time to reduce the bandwidth waste and the signaling cost. To verify our proposed scheme, an extensive simulation is performed through comparing EM-CSPMIPv6 with FMIPv6 protocol and GB-FH method. The results show that the EM-CSPMIPv6 increases the performance of system in terms of handoff latency, signaling cost and bandwidth usage when compared to the counterpart.

“…As a result, MN still can receive data without disconnecting when it moves from one subnet to the other, that is, handover between different subnets. Although Mobile IPv6 is designed to support mobility management, it suffers with longer handover latency and leads to non-negligible reduction of handover performance [2][3][4][5].…”

The fast handover Mobile IPv6 (FMIPv6) offers a handover preparation mechanism for a mobile node (MN) to reduce the handover latency over wireless network. However, FMIPv6 mainly deals with one MN instead of multiple MNs. In the wireless network, a group of MNs may move from the same previous network to the next network. In this paper, a group-based fast handover (GB-FH) control scheme is proposed to resolve the aforementioned problem. For the proposed GB-FH scheme, one MN initiates a handover preparation and other neighboring MNs can join the handover preparation using the "hitch-and-ride" concept, which means that when one MN is preparing for a handover, its neighbours can join the ongoing handover preparation. Through the use of the shared invocation of the handover preparation procedure, (1) the handover preparation delay and handover latency can be reduced for about 20% and 8% respectively comparing with FMIPv6, (2) handover control messages can be reduced for about 57% comparing with FMIPv6 and (3) the contention of the wireless channel for multiple MNs can be improved due to the use of fewer control messages.

RETRACTED ARTICLE: Improved fast handover method for multiple node by using mobile nodes guide

2016

The fast mobile internet protocol version 6 (FMIPv6) was suggested as a fast handover mechanism over the mobile wireless Internets in order to reduce the handover latency of a mobile node (MN). However, FMIPv6 was originally designed to deal with single MN's. In mobile wireless Internet, a multiple MNs may do a handover at the same time as a consequence of its movement from one network to another new one. This will therefore lead to the bandwidth waste and low handover performance. This paper intends to propose a multiple handover-based mobile node (MHB-MN) control method and an enhanced FMIPv6 mechanism in order to resolve the abovementioned problem. The proposal of such an MHB-MN method aims at having one mobile node work as a guide for a group of neighboring MNs. This means that the guide of MN prepares itself for a handover before actually taking the initial steps of the actual handover operation. Based on obtained results, it is plainly observable that by MHB-MN method, the handover initiation time, handover latency and handover control messages can be reduced compared to those of FMIPv6. Furthermore, the contention of the wireless channel for multiple MNs can be improved by the use of fewer control messages. Finally, the paper introduces an analytical model to show that by enabling the MHB-MN method and enhancing the FMIPv6 method, a multiple of nodes can perform rapid handover processes with low handover latency compared to that of the FMIPv6 technique.
