“…More related works using similar RATs and addressing industrial use cases can be found in [41][42][43]. Specifically, the authors of [41] presented a proactive handover method based on an assessment of the RSSI, the procedure of which remains rather similar to one of the handover methods considered in our work. However, the handover was considered between APs of the same RAT instead of a multi-RAT situation.…”

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.

“…Another similar research [7] used the UNIFI devices, the system enables end-to-end roaming for complete roaming, making it seamless and virtually uninterruptable. Another study defined that roaming becomes an important aspect because many applications rely on real-time communication and therefore need seamless handover between access points [23]. In [1] they proposed a method for securing WLAN, their approach focused on creating a network for a medium size office which has 3 subnets and several servers.…”

The demand for setting up a wireless LAN internet connectivity is almost mandatory for every commercial building, home, company, and educational institutions. With the growing number and height of buildings as well as the number of users, it has become essential to apply new techniques to provide better wireless network services, especially for security issue with many applications used by an attacker that can decrypt the traditional password to use network resources, that’s lead to poor network performance for providing network services for people authorized to use it. All of that is almost a very challenge issue when applying outdated techniques. In this research a wireless network has been created considering a large number of users in a multi-floor building using a new control system which can solve the problems by setting up RADIUS authentication via that wireless network with a webpage that automatically appears to the user immediately after connecting to the wireless radio signal and automatically gaining an IP address, lead user directly to the temporary page asking him for authentication, if the user has the right username and password or even sometimes a code called Voucher, he will get a package assigned to his priority. This technology will eliminate the vulnerability on the wireless connection and the unauthorized user will be discarded from the router, in addition of that authorized users will get authenticated to make better use of network resources.

Many modern-day applications require seamless connectivity to provide a good quality experience to mobile users. Thus, mobility management mechanism becomes a crucial aspect of all the wireless technologies used to connect to the Internet. In this letter, we present the testbed implementation details of a Network Address Translation (NAT)-based, client-unaware, seamless handover mechanism for a Software-Defined Enterprise WLAN framework. The results from the testbed implementation corroborate that the handover mechanism can provide uninterrupted connectivity during a handover process.
