Although there has been much interest in scaling laws for wireless networks, most work has focussed on characterizing throughput and delay in power-constrained networks. Energy-constrained networks have not received much attention. Previous work on energy- ...
To increase network capacity, it may not be sufficient to just increase the capacity of the networks. It may be necessary to reduce the network overhead bits, to leave more room for the data bits, to increase the network capacity. As network functions beco ...
In this paper we propose a set of necessary and sufficient conditions under which the throughput in an ad-hoc network can remain constant as the number of nodes n increases. Throughput refers to the minimum achievable rate between a source-destination pair ...
This paper presents a method for admission control and request scheduling for multiply-tiered e-commerce Web sites, achieving both stable behavior during overload and improved response times. Our method externally observes execution costs of requests onlin ...
We calculate the average throughput benefit that network coding can offer as compared to routing for different classes of multicast configurations over directed graphs. The averaging is over the throughput each individual receiver experiences. For the case ...
We derive performance expressions for the throughput and blocking probability for a class of wireless networks with a clustering protocol. The nodes are assumed stationary and establish connections with the master node according to a priority scheme that r ...
We consider a source that transmits to a receiver by routing the information packets over a communication network and examine rate benefits that finite complexity processing at the intermediate nodes may offer. We show that the processing capabilities of t ...
A method is proposed for the optimal scheduling of collective data exchanges relying on the knowledge of the underlying network topology. The concept of liquid schedules is introduced. Liquid schedules ensure the maximal utilization of a network's bottlene ...
Next generation wireless local area networks (WLANs) such as the IEEE 802.11n standard are expected to rely on multiple antennas at both transmitter and receiver to increase throughput and link reliability. However, these improvements come at a significant ...

We present a joint PHY/MAC architecture (DCC-MAC) for 802.15.4a-like networks based on PPM-UWB. Unlike traditional approaches it fully utilizes the specific nature of UWB to achieve high rates at low protocol complexity. It is the first MAC protocol that a ...
