Channel allocation is one of the fundamental issues in designing wireless communications systems due to the fact that it determines how the available bandwidth will be managed over the changeable user demands. The limited channel capacity and the increasing requirements for advanced services such as real time video grant channel allocation strategies a special role. Plethora of channel allocati...

Local area packetized-power network (LAPPN) provides flexible local power dispatching in the future Energy Internet. With interconnections among multiple LAPPNs, power dispatching can be further extended to intraand inter-LAPPN power interchanges. It becomes a significant issue to schedule the two kinds of power interchanges as, from a system perspective high utilization of available scheduling...

In progressive joint source-channel coding of images, experiments show that optimizing rate allocation according to PSNR criteria and according to rate criteria produce essentially similar results – a very important observation because optimization by rate is often much easier. This paper presents analysis to uncover the reason for – and the generality of – these empirical results. We first exa...

In order to maximize the system capacity in third generation wireless system, efficient call admission and load control algorithms are required to handle the different services having diverse traffic patterns and Quality of Service (QoS) requirements. We propose an admission and load control algorithm that considers the network loading information, propagation conditions, and the interference l...

Recent research and management experience has led to several frameworks for defining and managing carrying capacity of national parks and protected areas. The process outlined in contemporary carrying capacity frameworks embodies the principles of adaptive management. That is, management decisions are guided and adapted within these frameworks by monitoring indicator variables to ensure that st...
