- 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...

- Throughput Enhancement of IEEE 802.11 WLAN Via Frame Aggregation
- The popular IEEE 802.11 WLAN is known to achieve relatively small throughput performance compared to the underlying PHYsical layer PHY transmission rate. This is due mainly to the large overheads composed of Medium Access Control MAC header, PHY preamble/header, backoff time, ACKnowledgement ACK transmission, and some Inter-Frame Spaces IFSs. Since...
