Network Quality of Service (QoS) criteria of interest include conventional metrics such as throughput, delay, loss, and jitter, as well as new QoS criteria based on power utilization, reliability and security. In this paper we suggest a theoretical framework for the characterization and comparison of adaptive routing algorithms which use QoS as the criterion to select between different paths th...

A primary problem facing real-world robots is the question of which sensing actions should be performed at any given time. It is important that an agent be economical with its allocation of sensing when sensing is expensive or when there are many possible sensing operations available. Sensing is rational when the expected utility from the information obtained outweighs the execution cost of the...

The Segway Human Transport (HT) is a one person dynamically selfbalancing transportation vehicle. The Segway Robot Mobility Platform (RMP) is a modification of the HT capable of being commanded by a computer for autonomous operation. With these platforms, we propose a new domain for human-robot coordination through a competitive game: Segway Soccer. The players include robots (RMPs) and humans ...

When we are confronted with a living system, whose design is mysterious and whose optimizations are obscure, it is no easy task--as Professor Stein reminds us--to arrive at an answer to the question he has posed in this paper. Stein's target article is an important contribution for two main reasons. The first, which we shall mention only in passing, is that it is likely to provide much debate o...
