For a given terrain to be traversed, it is computationally intensive to determine the fastest route between two points, and for defense or civilian emergency dispatching applications, computation time is critical. This paper reports the integration of a 24 x 25 random access array of digital processors which are programmed to model a given terrain and determine the fastest (lowest cost) path fr...

Computerized systems are becoming smaller, ubiquitous and more interconnected. Netbooks to smart highways all are expected to be more autonomous and connected to each-other. Such interconnected systems have to manage information and regulate actions on their own, with minimal external guidance. A sensor network is a typical example. With scarce resources and no ready infrastructure, it forms a ...

In this paper we analyze in detail the energy consumption characteristics of the Wireless HART protocol when operated with a popular transceiver, the ChipCon CC2420. We analyze how much various factors contribute to the overall energy consumption over a longer period of 12 h. These factors include the amount of management traffic and the power levels required for various transceiver activities ...
