High-speed visible light communication (VLC) is a complementary technology to conventional radio frequency communication in wireless networks. One of the essential traits of VLC systems is the ability to provide wireless communication and illumination ...

Mobile cloud computing (MCC) is a technology which provides cloud server resources to mobile users with optimized latency. MCC allows mobile device to access cloud resources and to offload tasks to cloud let servers at any time and from anywhere. ...

This paper focused on the development of a system that could detect and locate falls, and identify the victims in a short period of time. The system used triaxial-accelerometer in detecting a fall, signal strengths from access points in locating the ...

Mobile ad hoc network (MANET) comprises a set of wireless nodes that provide communication benefits for users without any access points or centralised control. Owing to the highly dynamic wireless nature, MANET has many challenges such as limited energy, ...

Caching of the popular content in the storages of local nodes near to the users has been proposed as a promising approach to handle the network data traffic and the backhaul constraint of access points in the cellular networks. These local storages, also ...

Live video upstreaming refers to the flow of live data in the upstream direction from mobile devices to other entities across the Internet and has found use in many modern applications such as remote driving, the recent social media trend of live video ...

Location-based sharing services allow people to connect with others who are near them, or with whom they shared a past encounter. Suppose it were also possible to connect with people who were at the same location but at a different time -- we define ...

Channel bonding allows IEEE 802.11n clients to operate at a maximum rate of 300 Mbps which can significantly improve the network throughput. But at the same time it increases the co-channel interference to the nearby APs leading to a degradation of ...

Wireless body area networks (WBANs) can help in enabling efficient patient monitoring solution for ubiquitous healthcare. Communication in WBANs is undertaken in two phases: intra‐WBAN and extra‐WBAN. The prevailing WBANs use cellular network or WiFi in ...

The spatially distributed sparsity of the mobile devices (MDs) in indoor wireless local area networks (WLANs) makes compressive sensing (CS) based localisation algorithms feasible and desirable. In this Letter, the authors exploit the most recent ...

Frequency channels are allocated to the access-points (APs) satisfying the co-channel interference in an IEEE 802.11 WLAN. Very few APs can be activated simultaneously with a conflict-free frequency assignment to them, due to limited number of ...

Owing to limited resources, it is hard to guarantee minimum service levels to all users in conventional cellular systems. Although global cooperation of access points (APs) is considered promising, practical means of enhancing efficiency of cellular ...

To date, most tabletop systems are designed with only a single application visible and accessible at any time, which is, in many cases, an underuse of the tabletop spacious surface, and counter-intuitive to the normal working environment of a table. ...

Frequency channels are allocated to the access-points (APs) subject to an acceptable co-channel interference level in an IEEE 802.11 WLAN. Due to limited number of the non-overlapping frequency channels, all APs in a given area may not be activated ...

This poster reports the preliminary results of a user study uncovering the information seeking behaviour of humanities scholars dedicated to radio research. The study is part of an interdisciplinary research project on radio culture and auditory ...

This paper presents preliminary results from our ongoing research project which explores easy to use and useful facets in accessing consumer health information on the Web. In this pilot study, first, 10 facets were identified by analyzing 10 top ranked ...

A wireless local area network (WLAN) is a group of wireless networking devices within a limited geographic area, such as an office building, that exchange data through radio communications. The security of each WLAN is heavily dependent on how well each ...

Traditionally, business intelligence provides companies with important, but not real-time or predictive, analysis. Moreover, only technical specialists have typically run BI tools and have done so just for the benefit of management. Pervasive BI ...

Fears about hackers intruding into Wi-Fi networks and either stealing important information or planting malware have increased over the years. As a result, wireless intrusion-prevention systems are becoming increasingly important.

In this paper, a channel-assignment algorithm at the Access Points (APs) of a Wireless Local Area Network (WLAN) is proposed in order to maximize Signal-to-Interference Ratio (SIR) at the user level. We start with an initial channel assignment based on ...
