Throughput and Transmission Capacity of Ad Hoc Networks With Channel State Information: This paper develops a general framework for deriving the spatial throughput and transmission capacity of spatially Poisson distributed ad hoc networks for random (e.g., fading) channels, and random transmission distances. In both of these scenarios the randomness of the channels and ranges invariably lowers both throughput and transmission capacity assuming...; Tags: Channel, Advertisement, Throughput, Transmission Capacity, Networking; White papers 2006-07-05
Transmission Capacity of Wireless Ad Hoc Networks With Successive Interference Cancellation: The transmission capacity of a wireless ad hoc network can be defined as the maximum allowable area spectral efficiency such that the outage probability does not exceed some specified threshold.

On the Capacity of Mobile Ad Hoc Networks With Delay Constraints: Previous work on ad hoc network capacity has focused primarily on source-destination throughput requirements for different models and transmission scenarios, with an emphasis on delay tolerant applications. In such problems, network capacity enhancement is achieved as a tradeoff with transmission delay. In this paper, the capacity of ad hoc networks...; Tags: Mobile, Network, Network Capacity, Network Administration, Networking; White papers 2005-10-10

Transmit Optimization for MIMO-OFDM With Delay-Constrained and No-Delay-Constrained Traffic: This paper studies low-complexity power control schemes to approach the capacity limits of Multiple-Input Multiple-Output Orthogonal-Frequency-Division-Multiplexing (MIMO-OFDM) channels under the assumption that perfect Channel State Information CSI is available at both the transmitter and the receiver. Two notions of channel capacity limit are considered, namely, the ergodic capacity for variable-rate...; Tags: Optimization, Capacity, MIMO-OFDM; White papers 2006-08-01
Downlink Performance and Capacity of Distributed Antenna Systems in a Multicell Environment: Distributed antenna systems DAS have been widely implemented in state-of-the art cellular communication systems to cover dead spots.

On Scheduling and Real-Time Capacity of Hexagonal Wireless Sensor Networks: Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate time slots to the nodes of a network such that if the nodes transmit only during the allocated time slots, no collision occurs. For real-time applications, by...; Tags: Algorithm, University Of Virginia, Network, Collision, Sensor, Transmission, Engineering, Wi-Fi, Networking, Wireless; White papers 2007-04-21
