Abstract: A system, apparatus and method for providing an ad-hoc network of sensors. More specifically, the ad-hoc networked sensor system is based on novel network protocols that produce a self-organizing and self-healing network.

Abstract: A method and apparatus for expanding a mobile wireless telephony with minimal changes or modifications to an existing and installed wire-line telephony infrastructure that comprises a wireless base station that periodically transmits a wireless signal to initiate and maintain a wireless network. The wireless base station couples a wired signal to a wired telephone network. At least one RF enabled device is responsive to the wireless signal from the wireless base station to form the wireless network and provide the wired signal for coupling to the wired telephone network.

Abstract: A method for finding or routing a ring containing predetermined ring offices of a communications network while minimizing costs of communications channels used to route the ring. The ring may be a self-healing ring, the communications channels may be optical communications channels, the costs may be fiber transport costs and the network may be a SONET network.

Abstract: Monitoring of traffic on selected routes requires little communication time, through reporting only instances of abnormal speed. During a calibration phase calibrant vehicles are operated along the selected routes with sufficient frequency and for enough days to provide meaningful data. Each calibrant vehicle carries a differential GPS receiver for measuring location accurately. Average speeds for intervals of, for example, 15 seconds, are stored, with the time and place of observation. The data from all calibrant vehicles are then analyzed to determine patterns of mean speed and bandwidth. In the monitoring phase probe vehicles are deployed, each carrying similar GPS, a computer in which the patterns are stored, and a radio for automatically reporting speeds which are out of bandwidth for that time and place.
