In this article we analyze capacity improvement by directional antennas over omni antennas
in wireless sensor networks. The capacity in our analysis is the end-to-end per-node …

The deployment of directional antennas offers many advantages, such as transmission
range extension, co‐channel interference reducing, the increasing of spatial reuse degree …

Abstract Wireless Underground Sensor Networks (WUSNs) are the networks of wireless
sensors that operate in the underground soil medium. In this monograph, to realize reliable …

In this paper we propose a topology control algorithm for the wireless mesh network, where
each node is equipped with m non-steerable directional antennas. Our objective is to …

This chapter introduces the concept of multi-beam antenna (MBA) in mobile ad hoc networks
and the recent advances in the research relevant to this topic. MBAs have been proposed to …

Multihop cellular networks are expected to play an important role in the evolution towards
4G. In this work, we propose the use of advanced antenna techniques (adaptive antenna …

MANET (Mobile Ad hoc NETwork) 是一种无中心(分布式) 的无线通信网络.
它为区域内的移动或无线主机的互连提供了灵活的解决办法. 借助GPS 设备 …

In previous work, the effects of randomized beamforming, ie, the strategy of every node in a
wireless multihop network directing its antenna in a randomly chosen direction, on …

The increasing demand for gigabit-per-second speeds and higher wireless node density is
driving the need for spatial reuse and the utilization of higher frequencies above the legacy …

60 GHz has attracted a lot of commercial interest due to its abundance of unlicensed
frequency spectrum and the recent advances in building inexpensive transceivers. IEEE …
