… upper bound corresponding to an iid channel. Since, in most practical instances, all antennas
contribute positive power, this upper bound is usually achieved bolstering the importance …

… As explained, the employment of directional antennas has been shown to … We note that the
directional antennas model does not … In addition, we bound the edge capacities by the nodal …

… Later, extensive studies have been conducted to achieve a tighter capacity bound [2−6].
FRANCESCHETTI et al [2] applied percolation theory to obtain a per-node transmission …

Throughput scaling laws of an ad hoc network equipping directional antennas at each node
are analyzed. More specifically, this paper considers a general framework in which the …

… This paper investigates the connection between these properties and the capacity figures.
It … an upper bound, the uniform should not be regarded as a lower bound of the capacity. …

… However, by comparing the necessary and sufficient conditions, we bound the decrease in …
The ratio between the necessary and sufficient conditions gives the approximation bounds on …

… This is an ideal bound based on very nmow antenna beams not constrained by interference.
Several practical issues force us to make the actual epoch length much larger. These …
