In this paper, we propose an intelligent and distributed channel selection strategy for
efficient data dissemination in multi-hop cognitive radio network. Our strategy, SURF …

This paper introduces models and a system for designing 802.11 wireless LANs (WLANs)
using flexible channelization--the choice of an appropriate channel width and center …

The Access Points (APs) in a Wireless Local Area Network (WLAN) must be assigned one or
more channels to meet traffic demands from users. To date, prior works on channel …

Cognitive radio (CR) improves spectrum efficiency by allowing secondary users (SUs) to
dynamically exploit the idle spectrum owned by primary users (PUs). This paper studies …

Broadcasting is the simplest form of communication in which nodes disseminate the same
information simultaneously to all of their neighbors. Broadcasting has been widely used in …

Future green WiFi networks will require Access Points (APs) to minimize their energy usage
and maximize their spectral efficiency; equivalently, APs need to maximize their Energy …

Designed to adapt spectrum usage on-the-fly, frequency-agile radios can drastically improve
performance of wireless networks. Such flexibility, however, comes with a cost of increased …

IEEE 802.11 WLANs are becoming more and more popular in homes and urban areas. As
opposed to traditional WLANs, the access points (APs) in these networks are often deployed …

There is a significant interest in new wireless multiple access protocols that adaptively split a
wide frequency channel into multiple sub-channels—perhaps of varying widths—and assign …

Smart agriculture has a broad prospect with the fast development of information
technologies, such as Internet of Things, big data, edge computing and artificial intelligence …
