R-Cubed (R3): Rate, Robustness, And Recovery - An Availability Benchmark Framework
White Papers This paper identifies the three key attributes impacting system availability (fault and maintenance rate, robustness, and recovery), and methods to benchmark these key attributes of availability. This paper proposes a framework for benchmarking the...

Rate Allocation And Network Lifetime Problems For Wireless Sensor Networks
White Papers Since the objective of maximizing the sum of rates of all the nodes in the network can lead to a severe bias in rate allocation among the nodes, it advocates the use of Lexicographical Max-Min (LMM) rate allocation.

Rate Stable Resource Allocation In OFDM Systems: From Water-Filling To Queue-Balancing
White Papers The authors show, via a counter example, that water-filling based subcarrier allocation policies, contrary to conventional wisdom, fail to provide rate-stability for an otherwise stabilizable OFDMA system.

Correlations Of Size, Rate, And Duration In TCP Connections: The Case Against
White Papers This paper examines rigorously the evidence for correlations among size, rate, and duration in TCP connections. It was also found that correlation between size and rate is generally weak but can be strongly effected by applying thresholds to size...

Rate-Maximizing Power Allocation In OFDM Based On Partial Channel Knowledge
White Papers Two channel uncertainty models are studied: i) the ergodic model, where average rate is the figure of merit; and ii) the quasi-static model, where outage rate is relevant. Power loading algorithms improve the data rates of OFDM systems.
