A Mobile Ad hoc Network (MANET) is a collection of wireless mobile terminals that are able to dynamically form a temporary network without any aid from fixed infrastructure or centralized administration. In recent years, MANETs are continuing to attract the attention for their potential use in several fields such as military activities, rescue operations and time-critical applications. In this paper,...
This paper deals with a new multi-user linear precoding technique for downlink of distributed MIMO OFDM systems. We consider a distributed broadband wireless system where some base stations are transparently linked by optical fiber to a central unit. We further assume that the user terminals are equipped with an antenna array and the distributed base stations equipped with either single or an antenna...
This paper proposes the use of a wireless sensor network system as applied in a Smart Mining Camp to remotely control amenity functions and reduce energy consumption / emissions. Furthermore, we investigate such environmental sustainability and improved quality of life aspects through the use of multimedia convergence technologies.
As Wireless Mesh Networks (WMNs) are newly emerging wireless technologies, they are designed to have huge potential for strengthening Internet deployment and access. However, they are far from mature for large-scale deployment in some applications due to the lack of the satisfactory guarantees on security. The main challenges exposed to the security of WMNs come from the facts of the shared nature...
An Infrastructure Wireless Mesh Network (IWMN) is a multi-hop network that consists of stationary mesh routers, strategically positioned to provide a distributed wireless infrastructure for stationary or mobile mesh clients over a mesh topology. In this paper, we evaluate a scalable neighborhood discovery protocol, called SNDP, which has been specifically designed to detect the presence and status...
The paper provides a study on the use of Wireless Sensor Networks (WSNs) in refineries, petrochemicals, underwater development facilities, and oil and gas platforms. The work focuses on networks that monitor the production process, to either prevent or detect health and safety issues or to enhance production. WSN applications offer great opportunities for production optimization where the use of wired...
The paper proposed a distributed algorithm, namely CoBRA (Cone-based Barrier coveRage Algorithm), to achieve barrier coverage in wireless camera sensor networks (WCSNs). To the best understanding, CoBRA is the first algorithm which try to deal with the barrier coverage issue in WCSNs. Based on some observations, the basic concept of CoBRA is that each camera sensor can determine the local possible...
Both of mobile multimedia and mobile Internet are the important development directions of the mobile service. However, it would take on great cost by using the high data transmission rate of wireless multimedia communication service. Under the premise of not increasing the investment in hardware, the personalized service could be applied to the mobile service to not only reducing wireless multimedia...
RTLS (Real-time locating systems) are used for tracking the location of people or assets in real time. In general, these systems use the radio frequency (RF) for wireless communication within a local coverage area. However, when we attempt to apply this system to an indoor environment, the non-line-of-sight (NLOS) problem is critical to the system performance because of the obstacles in the room....
The monitoring of oil and gas plants using sensors allows for greater insight into safety and operational performance. However, as a result of strict installation regulations of powered sensors near oil and gas fittings, the introduction of new wired sensors to optimize end-of-lifecycle plants has been expensive, complex and time consuming. Recent advances in wireless technology have enabled low-cost...
The advances in distributed sensing and wireless communication enable pervasive home applications which are quit information-rich. Hereby the integrated access and management of heterogeneous information becomes an increasingly important research topic. Moreover recent popularity and advances in visual aids (Google maps, 3D computer graphics, PS games, etc.) call for the more attractively intuitive...
In the offshore engineering community, reliable deep-water anchor performance is critical for mooring floating platforms such as Mobile Offshore Drilling Units. In a typical installation, an anchor is fully embedded into the seabed (up to 100 m). This has to be done with high fidelity as anchor failure can cause floating units to go adrift, damaging oil and gas pipelines. The likelihood of this happening...
