  • Patent number: 7860019
    Abstract: Systems and methods for mobile peer-to-peer information sharing are disclosed. With the preferred systems and methods, mobile users and devices collect information about networks that they visit, and carry that information as they move to new networks. Mobile users and/or devices then share such information directly with each other.

  • Patent number: 7768982
    Abstract: This application sets forth, among other things, a new approach for real time collection, discovery, and sharing of network and user information, which we refer to as Autonomous Collaborative Information Collection, Discovery, and Sharing (AC-CDS). It is autonomous because regular mobile users and devices act autonomously to collect information and make the information available to others. It is collaborative as the autonomous actions of the mobile users and devices help each other to discover the information they want.

  • Publication number: 20100090841
    Abstract: Sensors mounted on vehicles (e.g., buses, taxis, police cars) and public personnel (e.g., policemen) are used to monitor various conditions and situations such as air quality, potential biological and chemical attacks, and road and traffic conditions. The invention improves upon the typical approach that deploys fixed sensors at every geographical position of interest. The total number of required sensors and the size and the complexity of the network infrastructure required to connect the sensors are reduced and simplified. A method for estimating the number of mobile sensors required to cover a region of interest also is disclosed. A relatively small number of mobile sensors may be sufficient to cover a large area at a lower cost and less complexity than a fixed sensor network.

  • Publication number: 20090285142
    Abstract: A system and method for maximizing the standby time of mobile communication devices that have WiFi or other high energy-consuming network interfaces, by predicting in real time actionable silent periods (ASPs) of the interface and shutting the interface down during these ASPs. Standby times are significantly increased, resulting in longer periods of operation before battery charging is required, while keeping minimal the probabilities of missing incoming data packets when the interface is turned off.

  • Patent number: 7380000
    Abstract: A mobile device receives wireless network information from a MIIS (Media Independent Information Server), and builds its own database of existing networks with their associated characteristics, appropriately mapped with GPS (Global Positioning Satellite) coordinates or other appropriate form of geographical location identifying information. Consequently, the mobile device becomes “smart” over time through the learning process of first attempting to utilize its own developed database and, only if such database information falls short, making a remote query to a MIIS to get required information for session continuity and performing handovers. The mobile device may store the information received from the MIIS in its own local database together with a time-stamp. Each time the mobile device needs to get updated or new information, it sends a request to the MIIS along with the time-stamp appended to the request.

  • Publication number: 20060227717
    Abstract: In some embodiments, a system and method for substantially real-time comparison of quality of interfaces by mobile devices over heterogeneous networks is disclosed. The method can be performed using a dynamic and rapid comparison by distributed hosts, using a minimal number of injected network packets, using minimal path quality metrics, which path quality metrics are independent of how a Qol is measured, and in a manner suitable for both wireline and wireless networks.

  • Publication number: 20050147084
    Abstract: This document describes Toll Free IP (TIP), a business model and its enabling methods to provide no-charge-to-user (“toll-free”) connectivity through IP-based access networks (e.g., public wireless hotspot networks based on IEEE 802.11), which may be operated by different network operators. With TIP, the use of networks to communicate with a toll-free IP destination will be paid by the owner of the toll-free IP destination. A toll-free IP destination can be identified in many ways, e.g., by a toll-free IP address, toll-free Internet Domain Name, a toll-free Universal Resource Identifier or Universal Resource Locator. TIP enables a user to use networks without prior service subscriptions with network or service providers and without any special terminal software or hardware for gaining permission to use a network. It allows users to use more access networks, i.e., larger “footprints”, than any individual network operator or aggregator can provide.

  • Publication number: 20050060390
    Abstract: A system and method are provided for adding network entities and appliances to a mobile wireless Internet. A graphical user interface on a user appliance or network entity is used to start a plug and play process. In the plug and play process a temporary IP address is assigned to the entity or appliance. The temporary address is tested for uniqueness. A search mechanism identifies and contacts a plug server that uses information from the user/operator to authenticate the user and/or validate subscription information. Upon authentication or validation the plug server dispatches an inspector agent to determine the software needs of the new entity or appliance. The plug server obtains the requested software from the software inventory and the inspector agent downloads the software onto the new entity or appliance and installs it therein. The element then uses the DRCP/DHCP client to obtain a new IP address.
