Cognitive radio is expected to be implemented in smart grids since it presents high
reliability, high accuracy and low transmission time by utilizing licensed bands …

A cognitive radio is designed for the utilisation of unused frequency. The transmission
opportunity of a cognitive node is not guaranteed due to the presence of primary users …

Today's wireless networks use fixed spectrum over long term and fixed geographical
regions. However, spectrum utilization varies by time and location, which leads to temporal …

In this paper, we investigate traffic engineering (TE) methods in Cognitive Radio Wireless
Mesh Networks (CR-WMNs) through joint selection of link-channel pairs at each forwarding …

在高密度AP 部署的网络环境中, 由于ISM 频带只有1, 6 和11 三个正交信道, 因此AP
的工作信道不可避免的存在重叠, 其重叠信道干扰对吞吐量有较大的影响. 文中从基于AP …

Channel allocation problem is a major challenge in wireless local area networks (WLANs),
especially in dense deployments of access points (APs) where congestion of the unlicensed …

Abstract Cognitive Sensor Networks (CSNs) are significantly different from the traditional
WSNs in terms of Cognitive Radio (CR) technology. According to the surrounding …

Capture-recapture models and curve-fitting models have been proposed to estimate the
remaining number of defects after a review. This estimation gives valuable information to …

Cognitive radio has been proposed as a promising technology to resolve the spectrum
scarcity problem by dynamically exploiting underutilized spectrum bands. Cognitive radio …
