“…With the proxy mobile IPv6 (PMIPv6) in mind, the authors of [10] investigated several handover schemes, such as fast handover for PMIPv6 (FPMIPv6), smart buffering, and low-latency handover, and compared the corresponding handover performance with the proposed location-aware fast PMIPv6 (LA-FPMIPv6). In particular, the FPMIPv6 aims at reducing the packet loss by scanning and detecting the network status of all APs around the source AP.…”

“…The handover is thus prepared once the RSSI of the source AP falls below a certain threshold. Similarly, the smart-buffering scheme, which also predicts the handover based on the RSSI, was proposed in [10] to reduce the packet loss. The main difference between smart-buffering scheme and FPMIPv6 lies in the fact that in the FPMIPv6 the UE scans the surrounding APs once handover decision is made, whereas for the smart-buffering scheme, the target AP, with which the UE is connected, searches for the source AP to retrieve the buffered packets.…”

“…In the context of multi-RATs and SCNs, seamlessly handing over to or selecting a network/RAT, which provides the best possible QoS to the UE, remains a crucial enabler of a self-organized communication system, in which the connected vehicles/robots are capable of performing efficient handover in a self-organized manner via the obtained location awareness, such that the throughput as well as the link quality are jointly optimized. Apart from the IEEE 802.21 multimedia-independent handover (MIH) standard that supports a QoS-based handover within the HetNets, several works [6][7][8][9][10][11][12][13][14][15][16][17][18] investigated the location-aware handover (LHO) and/or location-aware network selection (LNS) strategy ensuring that the mobile users have access to the required media service via the best available network. The objective of our work is therefore to investigate the feasibility and benefits of such efficient handover decision making schemes (i.e., the LHO) when integrating the positioning solutions.…”

The integration of millimeter wave (mmWave) and low frequency interfaces brings an unique opportunity to unify the communications and positioning technologies in the future wireless heterogeneous networks (HetNets), which offer great potential for efficient handover using location awareness, hence a location-aware handover (LHO). Targeting a self-organized communication system with autonomous vehicles, we conduct and describe an experimental and analytical study on the LHO using a mmWave-enabled robotic platform in a multi-radio environment. Compared to the conventional received signal strength indicator (RSSI)-based handover, the studied LHO not only improves the achievable throughput, but also enhances the wireless link robustness for the industrial Internet-of-things (IIoT)-oriented applications. In terms of acquiring location awareness, a geometry-based positioning (GBP) algorithm is proposed and implemented in both simulation and experiments, where its achievable accuracy is assessed and tested. Based on the performed experiments, the location-related measurements acquired by the robot are not accurate enough for the standalone-GBP algorithm to provide an accurate location awareness to perform a reliable handover. Nevertheless, we demonstrate that by combining the GBP with the dead reckoning, more accurate location awareness becomes achievable, the LHO can therefore be performed in a more optimized manner compared to the conventional RSSI-based handover scheme, and is therefore able to achieve approximately twice as high average throughput in certain scenarios. Our study confirms that the achieved location awareness, if accurate enough, could enable an efficient handover scheme, further enhancing the autonomous features in the HetNets.

“…Many WSN monitoring applications require mobility of sensor nodes; therefore, enabling node mobility has become a significant challenge in WSN research [ 4 , 5 , 6 ]. Many wireless standards and technologies do not efficiently support node mobility [ 7 ], impairing their use, especially if WSNs are being used for supporting critical applications with real-time constraints and reliability requirements.…”

Node mobility in multi-hop communication environments is an important feature of Wireless Sensor Network (WSN)-based monitoring systems. It allows nodes to have freedom of movement, without being restricted to a single-hop communication range. In IEEE 802.15.4 WSNs, nodes are only able to transfer data messages after completing a connection with a coordinator through an association mechanism. Within this context, a handover procedure needs to be executed by a mobile node whenever there is a disconnection from a coordinator and the establishment of a connection to another one. Many applications, such as those found in health monitoring systems, strongly need support for node mobility without loss of data during the handover. However, it has been observed that the time required to execute the handover procedure is one of the main reasons why IEEE 802.15.4 cannot fully support mobility. This paper proposes an improvement to this procedure using a set of combined strategies, such as anticipation of both the handover mechanism and the scan phase enhancement. Simulations show that it is possible to reduce latency during the association and re-association processes, making it feasible to develop WSN-based distributed monitoring systems with mobile nodes and stringent time constraints.
