TLDR
We use a stochastic model to study the throughput performance of various transport control protocol (TCP) versions (including its older version that we call OldTahoe), Reno, and NewReno) in the presence of random losses on a wireless link in a local network. Expand

Relay Selection for Geographical Forwarding in Sleep-Wake Cycling Wireless Sensor Networks
TLDR
We develop local forwarding algorithms that can be tuned so as to tradeoff the end-to-end delay against a total cost, such as the hop count or total energy. Expand

Fixed point analysis of single cell IEEE 802.11e WLANs: uniqueness, multistability and throughput differentiation
TLDR
We consider the vector fixed point equations arising out of the analysis of the saturation throughput of a single cell IEEE 802.11e wireless local area network with nodes that have different back-off parameters, including different Arbitration InterFrame Space (AIFS) values. Expand

Power constrained and delay optimal policies for scheduling transmission over a fading channel
TLDR
An optimal power and rate scheduling problem for a single user transmitting to a base station on a fading wireless link with the objective of minimizing the mean delay subject to an average power constraint. Expand

Optimal Association of Stations and APs in an IEEE 802 . 11 WLAN
We propose a maximum utility based formulation for the problem of optimal association of wireless stations (STAs) with access points (APs) in an IEEE 802.11 wireless local area network. Each STA canExpand

Performance evaluation of an IEEE 802.15.4 sensor network with a star topology
TLDR
We provide an analytical performance model for a network in which the sensors are at the tips of a star topology, and the sensors need to transmit their measurements to the hub node so that certain objectives are met. Expand
