Spectrum sharing is an emerging mechanism to resolve the conflict between the spectrum
scarcity and the growing demands for the wireless broadband access. In this paper we …

In wireless communications systems, it is well known that the instantaneous received signal
is a random variable that follows a given distribution. The randomness mainly stems from …

A space-time optimal power schedule for multiple distributed multiple-input multiple-output
(MIMO) links without the knowledge of the instantaneous channel state information (CSI) at …

Wireless sensor network of regular topology is efficient in area covering and targets locating.
However, communications with fixed channels lead to low spectrum efficiency and high …

Previous research on cognitive networks argues that secondary users can only work under a
low transmission power condition in an underlay spectrum sharing model. Motivated by the …

在无线传感网应用中部署规则拓扑结构能实现感知区域的完全覆盖和采集点的精确定位,
以较小的部署代价提供更好的网络性能, 为无线传感网的优化设计提供参照依据 …

The throughput of a large network of wireless routers critically depends on the design of
distributed medium access control (MAC). In this paper, a distributed MAC scheme called …

This thesis deals with the modeling of interference in a uniformly random wireless network
with fading. The channel access mechanism considered is slotted ALOHA, and to obtain a …

Lattices are important as models for the node locations in wireless networks for two main
reasons:(1) When network designers have control over the placement of the nodes, they …

The usages of wireless sensor networks (WSNs) are increasing day-by-day because they
can be deployed on the fly in almost no time in regions inaccessible or hard to reach for …
