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 use of directional antennas for wireless communications brings several benefits, such
as increased communication range and reduced interference. One example of directional …

We consider a wireless network of N nodes equipped with omnidirectional antennas, and
we extend the capacity results of some previous works by finding bounds on the maximum …

Connectivity is a crucial requirement for wireless sensor network deployments. Without
being able to guarantee a reasonable level of connectivity, many critical network operations …

Connectivity in sensor networks is an important metric that describes the capability of
networks to be able to report sensed information. The ability of member nodes to …

An Erratum has been published for this article in Wireless Communications and Mobile
Computing 2004; 4 (4): 473. We extend the previously well‐known results on the capacity of …

The capacity of wireless networks is limited by mutual interference between transmissions
by the different nodes. Deploying antennas that have a directional rather than omni …

The capacity of ad hoc wireless networks is constrained by the interference between
concurrent transmissions from neighboring nodes. Gupta and Kumar have shown that the …

Directional antenna offers a variety of benefits for wireless networks, one of which is the
increased spatial reuse ratio. This feature gives rise to the improved throughput through …

Recently, the use of directional antennas in multi-hop wireless networks has received
increasing attention in the research community due to their potential benefits and numerous …
