The number of hops between source node and destination node is a key parameter in
studying multi-hop wireless networks. Although hop count in wireless ad-hoc networks …

This paper presents a tractable analytical framework for the exact calculation of the
probability of node isolation and the minimum node degree distribution when N sensor …

We analyze topological entropy in wireless networks that are subject to local scattering and
macroscopic shadowing effects. To this end, we model a network as a random geometric …

The eavesdropping security of wireless ad hoc networks has attracted considerable
attention recently. However, most of current studies only consider OMN networks, where …

We investigate the local connectivity of cognitive radio ad hoc networks (CRAHNs), ie, node
degree and probability of node isolation. The local connectivity of CRAHNs depends on not …

This paper investigates the impact of using directional antennas and beamforming schemes
on the connectivity of cognitive radio ad hoc networks (CRAHNs). Specifically, considering …

In this paper, we present an analytical modeling framework for supporting and evaluating
the impact of shadowing and beamforming on the topological connectivity of cognitive radio …

Nodes in ad hoc networks with randomly oriented directional antenna patterns typically have
fewer short links and more long links which can bridge together otherwise isolated …

Directional antennas and beamforming can significantly improve point-to-point wireless links
when perfectly aligned. In this letter we investigate the extreme opposite where antenna …

This paper concerns the eavesdropping problem from the eavesdroppers' perspective,
which is new since most of previous studies only concentrate on the good nodes. We …
