In this paper, we consider wireless networks with directional antennas using slotted ALOHA
medium access control. The channel model incorporates the effects of propagation loss and …

In this paper we examine the effect of the receiver blocking problem on the performance of a
direct-sequence ad hoc network in which a subset of the nodes employ multiple directional …

In multi-hop wireless networks, per-hop forwarding strategies that optimize local
transmissions can have a subtle impact on network performance. Motivated by a number of …

This paper derives the exact outage probability and transmission capacity of ad hoc wireless
networks with nodes employing multiple antenna diversity techniques. The analysis enables …

Using directional antennas in wireless ad hoc networks can significantly improve network
performance. However, serious problems, such as the deafness and hidden terminal …

This paper derives the outage probability and transmission capacity of ad hoc wireless
networks with nodes employing multiple antenna diversity techniques, for a general class of …

Three collision-avoidance protocols are analyzed that use omni-directional packet reception
together with omni-directional transmissions, directional transmissions, or a combination of …

We study the performance of wireless ad hoc networks in the limit of a large number of
nodes. We first define ad hoc networks and their capacity. We then calculate a lower bound …

In this paper, we present an analytical model for evaluating the impact of shadowing and
beamforming on the connectivity of wireless ad hoc networks accommodating nodes …

This paper addresses the issue of deafness in directional antennas for wireless ad hoc
networks. Deafness is caused when a node X repeatedly attempts to communicate with …
