Wireless infrastructures have seen a drastic increase in energy requirements as technology shifted towards higher frequencies in an attempt to increase bandwidth. Driven by the increase in demand from an always increasing subscriber base, large cities are also demanding more base stations and access points to guarantee adequate quality of service. Mobile peer networking is a possible solution for...
Recent development in wireless ad-hoc metropolitan area networks (WMANs) has increased the demand for a new service portfolio based on client location. Potential services include location sensitive billing, push-activated social-networking, location-based experiences, and applications exploiting least-cost routing. This paper proposes a discrete time solution for a scenario in which a client application...
Exploitation of mobile peer networking in providing data and multimedia services has to-date been limited for a number of reasons, these include difficulties in addressing different ubiquitous radio access networks, cost per bandwidth, as well as increased TCP congestion due to reduced radio resources. A new mobile peer networking algorithm involving adaptive window techniques based on Linear-Quadratic-Gaussian...
Wireless geo-location applications require robust algorithms that are capable of locating and/or tracking wireless users requesting the service. To this effect, the performance of three neural network architectures has been evaluated through simulation to determine the optimal performance algorithm that can be applied to these new applications, such as location based-services (LBS). The results indicate...
A solution to mobile user location identification in 3G wireless systems based on a self-organising neural network architecture is presented. Radio signals from the mobile terminal's serving base stations are captured by the terminal, encapsulated and transmitted to the location detection server. These signals are fed to the neural network which translates the radio signals into neural coordinates,...
In the recent upsurge of ad-hoc wireless local area networks (WLANs) there has been an increased demand for a new services portfolio based on position. This has been accentuated due to the rise of 802.11/16 enabled chipsets inside mobile handsets. These services include location sensitive billing, profile selection based on specific indoor positions, and new location based applications such as automated...
