Delivering temporally-constrained multimedia streams in heterogeneous environments, ooering no guarantee in terms of bandwidth, packet loss, or delay, is a a very challenging problem faced today by both the networking and the coding community. Layered coding is often proposed as a solution for rate-based congestion control of video transmission in heterogeneous environments. The problem address...

Dedicated bus lanes provide a low cost and easily implementable strategy to improve transit service by minimizing congestion-related delays. Identifying the best spatial distribution of bus-only in order maximize traffic performance an urban network while balancing trade-off between priority regular disturbance is challenging task. This paper studies problem optimal dedicated lane allocation pr...

Most recently proposed wireless dynamic channel allocation methods have used carrier-to-interference (C/I) information to increase the system performance. Power control is viewed as essential for interference-limited systems. However, the performance of such systems under an imbalance of load among cells, as may occur often in microcells, is largely unknown. Here, we study a typical interferenc...

This paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. System engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (TCO...

Multicasting is an efficient and effective approach for supporting content distribution based on the current Internet infrastructure. In this paper, we have proposes the source-initiated CRMA (Cycle-breaking Rollback Multicast Routing Algorithm), which is a congestion-aware QoS (Quality of Service) based multicast routing algorithm. CRMA attempts to achieve the objective of minimizing network c...

A Cross – Layer based approach for the improvement of TCP performance in Multi – Hop Mobile Ad Hoc Networks is proposed in this paper. The proposed congestion triggering mechanism triggers congestion whenever the Channel Occupied Ratio reaches a maximum threshold value and the received signal strength is less than a minimum threshold value. Then, the Congestion Control scheme controls the data ...

Health systems around the world are grappling with the difficult issue of how to allocate scare healthcare resources. Within Europe many different approaches to healthcare resource allocation exist, but it is clear that the formal techniques of cost-effectiveness analysis are becoming increasingly important. This presentation will first address the fundamental economic principles of scarcity an...
