Wi-Fi is mission-critical in our personal and business lives. It’s in our homes, offices, hospitals, coffee shops, and on our flights. Great Wi-Fi is no longer a luxury—it’s a must have. Great Wi-Fi networks are stable, with high capacity and performance, that exceed our quality of experience (QoE) needs. However, most Wi-Fi networks today are only qualified for coverage, with basic element and...

Due to the fast increase of mobile traffic, most mobile network operators face the congestion issue in licensed spectrum bands. Several telecommunication vendors and operators propose to expand LTE service to the unlicensed spectrum bands to relieve the traffic congestion. However, LTE in unlicensed spectrum may interfere with Wi-Fi communications in the same bands and cause significant decreas...

Android devices are portable, equipped with powerful processors, and can act as both mesh routers and clients through Wi-Fi Direct, making them a suitable platform from which to deploy a wireless mesh network. To allow Android devices to automatically establish and participate in a wireless mesh network, we circumvent two key problems of the Android’s Wi-Fi APIs: lack of direct support for ad-h...

Cities around the world are currently considering building expensive Wi-Fi infrastructure. In urban areas, resident operated Wi-Fi access points (APs) are dense enough to achieve ubiquitous Internet access, provided we can induce the hosts to provide guest Wi-Fi access. However, sharing Wi-Fi involves taking on responsibility for the guest’s actions. Our main contribution is a novel mechanism t...

This paper presents a dominant channel occupancy (DCO) mechanism for the Wi-Fi backscatter uplink in the industrial Internet of things (IIoT). The DCO provides high-priority channel access and reliable burst transmission to the Wi-Fi backscatter devices, thereby enabling the Wi-Fi backscatter tag to deliver its tag information to the Wi-Fi reader without interference from neighboring legacy Wi-...

Wi-Fi Direct is a popular wireless technology which is integrated in most of today’s smartphones and tablets. This technology allows a set of devices to dynamically negotiate and select a group owner which plays the role access point. This important feature is the strength of Wi-Fi Direct and makes it more and more widely used in telecommunications networks. In this paper, we present the implem...

The development of wireless broadband access network (WBAN) leads to enhance the insufficiency of unoccupied radio resources. This is quite expected in coming times, wireless cellular technologies and wireless local area networks (WLANs) will work together in coexistence scenario within the alike unlicensed spectrums (USs). Although, two most emerging wireless networks, i.e., Long Term Evaluati...

Smart classroom has been a boon in the field of education. But when it comes to individual evaluation of education and development of kids in a classroom, this would require one to one intervention. KIDS is an Android based kids educational evaluation system we propose to implement over Wi-Fi Direct to be deployed in a smart classroom environment to evaluate and help kids to improve their learn...

Recently, smartphones are widely used due to the popularity of Internet, and they are equipped with both Wi-Fi and cellular radio interfaces generally. In smartphone, although Wi-Fi interface is generally used for supporting higher rate data session of the smartphone itself, it can be also used to support connectivity to other nearby wireless devices with Wi-Fi interface only, such as laptop. T...

Intrusion Detection System (IDS) has been becoming a vital measure in any networks, especially Wi-Fi networks. Wi-Fi networks growth is undeniable due to a huge amount of tiny devices connected via Wi-Fi networks. Regrettably, adversaries may take advantage by launching an impersonation attack, a common wireless network attack. Any IDS usually depends on classification capabilities of machine l...
