01 Apr 2007TL;DR: An analytical framework is presented to study the self-adaptive behavior of probabilistic routing protocols for computer networks, based on a Markov chain analysis, which can be estimated without resorting to expensive Monte-Carlo simulation of the whole system.
Abstract: An analytical framework is presented to study the self-adaptive behavior of probabilistic routing protocols for computer networks. Such soft routing protocols have attracted attention for delivering packets more reliably, robustly, and efficiently than conventional deterministic approaches. Efficient global operating parameters can be estimated without resorting to expensive Monte-Carlo simulation of the whole system. Key model parameters are routing sensitivity and routing threshold/noise, which control the "randomness" of packet routes between source and destination, and a metric estimator. Global network characteristics are estimated, including steady state routing probabilities, average path length, and path robustness. The framework is based on a Markov chain analysis. Individual network nodes are represented as states. Standard techniques are used to find primary statistics of the steady state global routing pattern, given a set of link costs. The use of packets to collect information about, or "sample," the network for new path information is also reviewed. How the network sample rate influences performance is investigated.

28 Dec 2000TL;DR: In this paper, a mobile phone has a scanner or barcode reader, integral with phone or detachable with connecting cable or infrared interface, which provides choice of scanner and its functions for text recognition, bar code recognition and symbol recognition.
Abstract: Mobile phone has scanner or barcode reader, integral with phone or detachable with connecting cable or infrared interface. Phone menu provides choice of scanner and its functions for text recognition, bar code recognition and symbol recognition. Mobile phone has scanner or barcode reader, integral with phone or detachable with connecting cable or infrared interface. Phone menu provides choice of scanner and its functions for text recognition, bar code recognition and symbol recognition. Handwritten or printed text is scanned in and integral optical character recognition software, on SIM or permanent in phone, recognizes characters. Recognized text is shown on phone display, confirmed by user and transmitted. Set text converted to bar code is scanned by bar code reader integrated in phone to transmit specific messages.

14 Aug 2003TL;DR: In this article, a method for notification and ordering of electronic messages, especially voicemail and text messages to a phone, is presented, in a first step, messages received by the message receiving system are analyzed with voicemail messages first being converted into text.
Abstract: Method for notification and ordering of electronic messages, especially voicemail and text messages to a phone. According to the method, in a first step, messages received by the message receiving system are analyzed with voicemail messages first being converted into text. In a second step the messages are prioritized based on the analysis. Finally the messages are provided to the user based on the priority criteria. The invention also relates to software and a computer system for implementation of the inventive method.

29 Oct 2008TL;DR: In this paper, a method for producing an electromagnetic carrier wave in the frequency range between 0.1 and 10 terahertz that is suitable for the wireless transmission of data is presented.
Abstract: A method for producing an electromagnetic carrier wave in the frequency range between 0.1 and 10 terahertz that is suitable for the wireless transmission of data includes generating, by an electromagnetic pump wave, at least two mixing waves with a defined frequency difference, the pump wave being configured to constitute one of the mixing waves; and producing an electromagnetic carrier wave by frequency mixing the mixing waves.

13 Mar 2006TL;DR: In this article, the problem of approximating the number of differences between sets held on remote hosts using minimum communication is considered, and a heuristic solution based on the counting Bloom filter is proposed.
Abstract: We consider the problem of approximating the number of differences between sets held on remote hosts using minimum communication. Efficient solutions to this problem are important for streamlining a variety of communication sensitive network applications, including data synchronization in mobile networks, gossip protocols and content delivery networks. Using tools from the field of interactive communication, we show that this problem requires about as much communication as the problem of exactly determining such differences. As a result, we propose a heuristic solution based on the counting Bloom filter. We provide analytic bounds on the expected performance of our protocol and also experimental evidence that they can outperform existing difference approximation techniques.
