As the services have increased many fold with variety of data types pumped into network, which included multimedia and fast changing conditions. The problem of congestion has also increased and posing the threat to Network performance and degradation of throughput due to change in topology and drawbacks in routing algorithms. In this paper, two a new routing protocol Advanced Optimized Link State...
Integrated Mobile Broadcast (IMB) is a technology recently standardized by 3GPP for delivery of broadcast multimedia via a cellular network. IMB is based on WCDMA technology but particularly designed for deployment in 3G TDD spectrum. It employs downlink-only channels using SFN methods, which greatly increase spectral efficiency and capacity for broadcast services. In this paper, we firstly provide...
A personalised mobile sports event viewing system that enables users to efficiently and naturally direct movies of their own live sports events on mobile devices is described. Personalisation here focuses on the selection of live events with respect to multiple sports disciplines. An implicit user model driven approach is used to enable the system to adaptively predict users' preferred events during...
The paper studies the multipath characteristics of the wideband channels at 3.5 GHz in a typical outdoor urban environment. A channel measurement system for this frequency band was developed; Based on the measurement data, the channel modeling parameters including the tapped delay line models, the multipath distribution, the excess delay and the Ricean K-factor were extracted. Then by using the measured...
A novel analytical approach is developed for determining the maximum traffic intensity for Low Earth Orbit Mobile Satellite Systems (LEO-MSS) under preset Quality of Service (QoS) constraints such as call blocking and dropping probabilities. The proposed methodology also enables the optimization of channel reservation for handovers so that the traffic intensity supported by LEO-MSS is maximized.
