Wireless communication networks are facing a paradigm shift. New generations of cellular and ad hoc networks are finding new application areas, be it in commercial communication, for military use or disaster management. From providing only voice communications, wireless networks aim to provide a wide range of services in which soft real-time, high priority critical data, and best effort connect...
New schemes for video transmission over wireless channels are described. Content based approaches for video segmentation and associated resource allocation are proposed. We argue that for transport over wireless channels, diierent video content requires diierent form of resource allocation. Joint source/channel coding techniques (particularly content/data dependent FEC/ARQ schemes) are used to ...
Unmanned aerial vehicle (UAV)-enabled communication has emerged as an irreplaceable technology in military, disaster relief and emergency scenarios. This correspondence investigates the average throughput a UAV-enabled cognitive radio network, where UAV is regarded dedicated secondary user to enhance network coverage spectral efficiency. Based on probabilistic line-of-sight channel, we exploit ...
Elevated atmospheric CO2 concentration (eCO2) has the potential to increase vegetation carbon storage if increased net primary production causes increased long-lived biomass. Model predictions of eCO2 effects on vegetation carbon storage depend on how allocation and turnover processes are represented. We used data from two temperate forest free-air CO2 enrichment (FACE) experiments to evaluate ...
in this research, both resource allocation and reactive resource allocation problems in multi-server dynamic pert networks are analytically modeled, where new projects are expected to arrive according to a poisson process, and activity durations are also known as independent random variables with exponential distributions. such system is represented as a queuing network, where multi servers at ...
introduction: family physician plan in iran was conducted to establish service referral system. its urban step began in 2012 and it was supposed that the effectiveness is enhanced and the costs are reduced. the implementation of this program has faced some challenges, especially in human resources management. the aim of this study was to optimally allocate human resources for urban family physi...
the research on project scheduling has widely expanded over the last few decades. the vast majority of these research efforts focus on exact and suboptimal procedures for constructing a workable schedule, assuming complete information and a static deterministic problem environment. project activities are scheduled subject to both technological precedence constraints and resource constraints, mo...
We consider a general problem of optimal allocation of a homogeneous resource (bandwidth) in a wireless communication network, which is decomposed into several zones (clusters). The network manager must satisfy different users requirements. However, they may vary essentially from time to time. This makes the fixed allocation rules inefficient and requires certain adjustment procedure for each s...
