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...

Wi-Fi tethering (i.e., sharing the Internet connection of a mobile phone via its Wi-Fi interface) is a useful functionality and is widely supported on commercial smartphones. Yet existing Wi-Fi tethering schemes consume excessive power: they keep the Wi-Fi interface in a high power state regardless if there is ongoing traffic or not. In this paper we propose System to improve the power efficien...
