With a few exceptions, most of the research dealing with power allocation, and more recently power/rate allocation in DS-CDMA based networks has concentrated on centralized resource allocation algorithms for cellular systems where the base station keeps track of the service requirements and is thus responsible for the management of network resources. Adhoc WLANS, howeveq are configured as peer-...

Simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. In this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of FDMA based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with Fuzzy distributed H∞ control strategy ....

Multi user resource allocation is one of the key features towards high speed wireless network based on Orthogonal Frequency Division Multiplexing Access (OFDMA). According to IEEE802.16m (Mobile WiMAX) standard resource allocation problem has to be performed on a frequency and time two-dimensional space with the Physical and logical resource units (PRU and LRU) including Distributed logical res...

Data mining is currently a frontier research topic in the field of information and database technology. It recognized as one most promising key technologies. involves multiple technologies, such mathematical statistics, fuzzy theory, neural networks, artificial intelligence, with relatively high technical content. The realization also difficult. In this article, we have studied basic concepts, ...

BACKGROUND With the depth development of health care system reform in China, emergency medical services (EMS) is confronted with challenges as well as opportunities. This study aimed to analyze the equity of China's EMS needs, utilization, and resources distribution, and put forward proposal to improve the equity. METHOD Three emergency needs indicators (mortality rate of cardiovascular and c...
