March 15, 2007: Conference paper (prolonged with an appendix) that describes specification and our simulation results for each the delayed and delay-less setting is now accessible. 1. Formal Modeling and Analysis of the OGDC Wireless Sensor Network Algorithm in Real-Time Maude. By Peter C. Ã–lveczky and Stian Thorvaldsen. This is a paper that explains the specification of OGDC and the simulation results in the completely different settings, in addition to giving some mannequin checking commands. More recent than the references beneath. 2. Formal Modeling and Analysis of the OGDC Wireless Sensor Network Algorithm in Real-Time Maude. By Stian Thorvaldsen and Peter C. Ã–lveczky. 26 web page report on our work. That is the primary reference to our work on the OGDC algorithm. Also obtainable in ps format. 3. Formal Modeling and Analysis of Wireless Sensor Network Algorithms in Real-Time Maude. By Peter C. Ã–lveczky and Stian Thorvaldsen. The paper is extra a high-stage” paper that motivates why Real-Time Maude may be appropriate to specify and analyze wireless sensor networks.
It presents a brief overview of some common methods for modeling wireless sensor community algorithms in Real-Time Maude and only very briefly summarizes the OGDC case study. 4. Modeling and Analysis of the OGDC Wireless Sensor Network Algorithm in Real-Time Maude. This is an extensive report on the real-Time Maude 2.1 specification and analysis of the OGDC algorithm. Essentially superseded by the report (2) above. 5. Maintaining Sensing Coverage and Connectivity in Large Sensor Networks. By Honghai Zhang and Jennifer C. Hou. The real-Time Maude file: ogdc.rtmaude – Easy methods to execute/analyze these specs? Start Real-Time Maude 2.2. – Load the above file ogdc.rtmaude. The various analysis commands are given at the end of this file, but are commented away simply remove the ‘—‘ elements across the commands, or minimize-and-paste the desired command onto the Maude command line. Please observe that many of the rewriting and analysis commands take some time, even hours, to execute. In a first execution, you might well need to decrease the number of nodes, or the variety of rounds, significantly. Also observe that the states are fairly massive, so might wish to re-direct your output to a file, or pipe it to another program. We now have very barely modified our specs (a RTM 2.2 spec additionally executes on RTM 2.3), and have outlined a version that makes use of Maude’s built-in Mersenne Twister pseudo-random number generator as a substitute of our house-made one. The distinction in efficiency estimates is just not important.
More than another aspect, the factor that has at all times fascinated me essentially the most about computers is the infinite potential for exploration they provide. You possibly can create anything–whether or not actual or imagined–inside a computer, after which you may make it do anything you want. You’re free to try and make your creations mimic the true world as a lot as possible, or you are free to go ahead and bend whatever rules of actuality you want. Not surprisingly, a majority of pc programs that embody this spirit are video games. Games are enjoyable, however video games can be extra than simply pure leisure. Games can enlighten people and make us suppose in particular ways in which a passive type of media, like a film, can’t. The applications listed on this web page are, for the most part, clearly games, though there are a number of that some would possibly argue are some sort of software program hybrid maybe “edutainment” (entertainment software program for the purpose of training), or actual-world simulation.
Nonetheless, I rather loosely use the label “game”, and hope that nobody might be offended by this utilization. I additionally hope that nobody will likely be moved to assume of these programs as shallow or insignificant simply because they are experimental or because they’re “video games”. Although, after all, a few of them are additionally only for enjoyable. Nonetheless, these are packages which I consider deserve special recognition as defying the commonly held concepts about what a computer game can or should be. Creativity, exploration, and experimentation are three relatively different things, so it’s perhaps acceptable to spend a second distinguishing how every of those labels applies to a computer recreation. Although “Creativity” suggests originality on the a part of the sport designer, what’s maybe extra essential is how a lot creativity the sport permits for (and encourages in) the player. A sport like Stunts, the traditional car-racing sport, is fun just because it gives you lots of fast automobiles to race around, nevertheless it also developed a small subculture of observe designers due to its in-sport monitor editor.
Games like this, which allow you to freely modify them, permit for you to specific your own creativity, bending the game in instructions that even the designer(s) probably didn’t foresee. Although many video games today encourage exploration, they typically achieve this by the brute-pressure technique of simply having very massive gameworlds which require rather a lot of knowledge. The basic RPG Betrayal At Krondor proudly boasted 224 million sq. ft of space to explore at your will. That’s clearly lots of floor, but distinction this with the extremely-simple Game Of Life, which doesn’t need a lot code and has very simple rules, but which enthralled folks for months on finish when it came out. The depth of a recreation would not necessarily must be in just how massive it is a game can derive infinite depth with the appropriate idea. Finally, “Experimentation” is kind of a double-edged sword. As in different types of art, like music and films, experimentation tends to lead to genuinely bizarre issues that make you surprise whether or not they’re sensible pushing the envelope of what a medium is able to, or simply completely wasting everybody’s time.
