WiMAX: An analysis of the existing technology and compare with the cellular networks. Abstract Broadband access technology has significant influences in the telecommunication industry. Worldwide interoperability for microwave access (WiMAX) is a broadband wireless technology which brings broadband experience to a wireless context. There are two different types of broadband wireless services. On...

Ubiquitous positioning provides continuous positional information in both indoor and outdoor environments for a wide spectrum of location based service (LBS) applications. With the rapid development of the low-cost and high speed data communication, Wi-Fi networks in many metropolitan cities, strength of signals propagated from the Wi-Fi access points (APs) namely received signal strength (RSS)...

The Internet of Things (IoT) – connection of small smart sensors, actuators and other devices to the Internet – is a key concept within the smart home. To ease deployment, such devices are often wireless and battery powered. An important question is the wireless interface used. The ubiquity of WiFi in homes today makes this an attractive option, but the relatively high power requirements of Wi-...

Pervasive positioning provides uninterrupted positional information in both indoor and outdoor locations for a wide spectrum of location based service (LBS) applications. With the rapid enlargement of the low-cost and high speed data communication, Wi-Fi networks in many metropolitan cities, strength of signals broadcasted from the Wi-Fi access points (APs) namely received signal strength (RSS)...

Wi-Fi throughput enhancement is required for the Tokyo Olympic in 2020. This is mainly because Wi-Fi can be a monetary-cost-effective solution for foreign tourists. However, especially in urban areas, Wi-Fi access points (APs) have deployed densely for the coverage enhancement of each service. Due to the dense deployment, there is a chaotic and disorderly environment in urban cities. Chaotic fr...

Motivating students to learn Wi-Fi (wireless fidelity) wireless networking to undergraduate students is often difficult because many students find the subject rather technical and abstract when presented in traditional lecture format. This paper focuses on the teaching and learning aspects of Wi-Fi networking using limited hardware resources. It provides a walk-through tutorial on setting up Wi...

In this paper, we consider a novel denial of service attack targeted at popular smartphone operating systems. This type of attack, which we call a Denial of Convenience (DoC) attack, prevents non-technical savvy victims from utilizing data services by exploiting the connectivity management protocol of smartphones' operating systems when encountered with a Wi-Fi access point. By setting up a fak...
