Early simulation experience with wireless ad hoc networks suggests that their capacity can
be surprisingly low, due to the requirement that nodes forward each others' packets. The …

As the field of communications networks continues to evolve, the challenging area of
wireless sensor networks is rapidly coming of age. Recent advances have made it possible …

Network congestion occurs when offered traffic load exceeds available capacity at any point
in a network. In wireless sensor networks, congestion causes overall channel quality to …

Abstract The Open Spectrum approach to spectrum access can achieve near-optimal
utilization by allowing devices to sense and utilize available spectrum opportunistically …

Link-layer fairness models that have been proposed for wireline and packet cellular
networks cannot be generalized for shared channel wireless networks because of the …

The IEEE 802.11 wireless media access standard supports multiple data rates at the
physical layer. Moreover, various auto rate adaptation mechanisms at the medium access …

In this paper, we study the problem of joint routing, link scheduling and power control to
support high data rates for broadband wireless multihop networks. We first address the …

Fairness is an important issue when accessing a shared wireless channel. With fair
scheduling, it is possible to allocate bandwidth in proportion to weights of the packet flows …

In a wireline network, nodes form links with only those nodes they are wired to, and the links
do not interfere with one another. In contrast, in a wireless network, signal transmissions are …

These experiments examined the effects, on retention, of posttraining intra-amygdala
administration of norepinephrine (NE), and propranolol. Rats were trained on a one-trial …
