Employing multiple channels to improve the multi-hop wireless network performance has
recently attracted a lot of attention. Given that hidden node collision is a key cause of the …

Complex self-organizing cognitive radio (CR) networks serve as a framework for accessing
the spectrum allocation dynamically where the vacant channels can be used by CR nodes …

We present a simulation-based study of the impacts of channel switching overhead on the
performance of multicast in multi-channel multi-radio wireless mesh networks (MCMR …

针对移动自组网中介质访问控制层协议的特性, 结合实际工程需求, 基于I-序列顶点着色算法,
提出一种N-时分多址动态时隙分配协议. 对协议的帧结构, 交互过程及动态时隙分配算法进行 …

Energy consumption is a significant issue and offers a rich scope for research in ad hoc
networks. However, many energy efficiency routing protocols are configured to use only a …

In this work, we study how to predict the popularity of an article in the largest terminal-based
bulletin board system (BBS) and also one of the most major social media, PTT (ptt. cc), in …

This paper describes a radio architecture for distributed spectrum sharing among secondary
users (SUs) in a localized area and a wide band of frequencies. Based upon an orthogonal …

Когнитивные сети (CN) на основе программно-конфигурируемого радио SDR являются
актуальной темой среди исследователей беспроводных сетей. Возможности CN и …

This thesis proposes a remotely controlled motor drive system which is able to supply a
regulated voltage for both DC and AC motors. The proposed system integrates two different …
