Infrastructure for accessing a peer-to-peer network environment

Embodiments of a system and method for providing peer-to-peer (p2p) capabilities to devices with limited resources (e.g. wireless devices). A mechanism is described that allows the devices to participate as peer nodes in p2p network environments through wired or wireless connections. In one embodiment, the p2p network environment may be implemented according to a p2p platform, and the mechanism may be interoperable with p2p platform devices in the p2p network environment. A relay / proxy node on the network may serve as an interface to the p2p environment for devices using the mechanism to participate as peers in the p2p network.

Relay peers for extending peer availability in a peer-to-peer networking environment

A system and method for allowing peers to exchange messages with other peers independently of their network location in a peer-to-peer environment. Messages may be transparently routed, potentially traversing partitions (e.g. firewalls and NATs), and using different protocols to reach the destination peers. In one embodiment, any peer node may serve as a relay peer that allows peers inside a partition to have a presence outside the partition and provides a mechanism for peers outside partitions to discover and communicate with peers inside the partitions. In one embodiment, a relay peer may maintain information on routes to other peers and assist in relaying messages to other peers. In one embodiment, any peer may query a relay peer for route information. In one embodiment, messages may include routing information as part of their payloads.

System and method for locating and communicating with personnel and equipment in a facility

This invention provides a system and method for identifying, locating, authorizing by proximity and communicating with equipment and personnel in a facility that generally employs a series of limited range transceivers for location determination and a distributed wireless data network for data transfer. The system employs unique RF transceiver tags on personnel and equipment that are each uniquely identified and registered with a facility control application that oversees activities in the facility. The tags are tracked by RF communication based upon their proximity to one or more fixed-base networked access points and relays (which transfer location data by RF back to access points) within four range zones. Location data on all tags is uploaded periodically to a location server that interfaces with the facility control server. Tag data is monitored by the facility control server to track, authorize and deauthorize certain data transfers, movements and activities in accordance with rules established for each tag (or type of tag) within the facility control server's application. Wireless networking (WiFi, for example), in combination with the RF-derived location information, allows the facility control server to correlate and transmit data to staff in conjunction with location and proximity. WiFi can transmit authorizations, deauthorizations and general data based upon triggers established by proximity and location. Likewise, data can be transmitted over WiFi from readers etc. from personnel and equipment located and identified by the system.

Method and system for distributing advertisements over network

A communication terminal sends an access request to a WWW server connected to a network to a relay server in the network. The relay server sends this access request to the WWW server and receives display data from the WWW server and sends an advertisement ID specifying an advertisement satisfying a predefined condition to the communication terminal together with the display data. The communication terminal displays a screen by this display data and sends an advertisement data request including an advertisement ID received from the relay server through the relay server to an advertisement distribution server. When receiving an advertisement data request, the advertisement distribution server sends the advertisement ID contained in the advertisement data request to the communication terminal through the relay server. When receiving the advertisement data, the communication terminal displays an advertisement corresponding to the advertisement data along with the screen corresponding to the display data.

Methods and systems for a wireless routing architecture and protocol

The present invention provides a method for generating routing paths in a multi-hop network. The multi-hop network includes a base station, at least one relay station, and at least one non-relay mobile station. The routing paths are paths between the base station and the at least one non-relay mobile station via the at least one relay station. The base station broadcasts a path discovery message (PDM) including a path list with a starting point of the path list being the base station. Each of the relay stations receives the PDM and updates the PDM by adding their own respective node identifier to the path list and broadcasting the updated PDM. The PDMs eventually reach the non-relay mobile station. The non-relay mobile stations reply to the base station by sending the base station the updated path list between the base station and the non-relay mobile station. In some embodiments the base station or the at least one non-relay mobile station acting as a source node sends a dynamic service (DSx) message including an end-to-end path list to an end of path destination. The relay stations use the path list to forward the message between the source node and the end of path destination. In some implementations the multi-hop network operates in a manner that is consistent with any one of: IEEE 802.16, IEEE 802.16d, and IEEE 802.16e.
