20090175223 | System and Method for Mobile Ad Hoc Network - A method and system for geocasting data packets in a MANET. The MANET is combined with a long-range network such that a wireless terminal can decide whether to rebroadcast a geocast packet over the MANET, the long-range network, or not at all, depending on the wireless terminal's proximity to the geocast region, the location of the originating wireless terminal, or both. A wireless terminal close to or within the geocast region can rebroadcast on the MANET, whereas a wireless terminal far from the geocast region can rebroadcast on the long-range network. | 07-09-2009 |
20100067451 | Quality of service scheme for collision-based wireless networks - A method for enabling different priority messages in a contention-based wireless network where units use a common channel. Relative to high priority messages, if the channel is not busy when a message is ready for transmission, then the message is transmitted immediately. When the channel is busy, the message is not transmitted until the channel becomes available and a selected back-off period (while the channel is available) expires. Back off periods are illustratively randomly selected by the units. Low priority messages are similarly not transmitted when the channel is busy, and additionally are not transmitted for a preselected pre-emption interval when the channel is available to high priority messages but not to low priority messages. Like with high priority messages, low priority messages that not transmitted when ready are held back a back-off period before they are transmitted. | 03-18-2010 |

The published content may be in an XML-based format and transformed into an XML-related format or any other structured language format as desired in the provided specification. | 07-12-2012 |
20130242956 | NON-INTERFERENCE TECHNIQUE FOR SPATIALLY AWARE MOBILE AD HOC NETWORKING - A system and method for reducing interference between wireless terminals communicating in a mobile ad-hoc network (MANET). Interference is reduced by dividing the MANET into a number of geographical areas having a specific size and shape. Each geographical area is assigned a time slot during which wireless terminals located in the respective geographical area may transmit to other wireless terminals. The time slots are assigned such that geographical areas having the same time slot are far enough away from each other that wireless terminals located in such same time slot geographical areas are outside the interference range of each other. | 09-19-2013 |
20130244564 | CAMPUS ALERTING VIA WIRELESS GEOCAST - A geocast alerting system employs wireless geocast transmissions to deliver customized alerting messages to particular geographic areas. Geocast alerting regions and sub-regions can be defined within the system. Upon notice of the occurrence of an emergent situation, one or more geographic areas that may potentially be affected by the emergent situation are determined. The potentially effected geographic regions are compared with geocast alerting regions and sub-regions corresponding to particular geographic areas. Target alerting regions that should receive alerting messages are identified based on the comparison. The content of alerting messages can be tailored for each target alerting region. The content of alerting messages can contain distinct portions of content, each portion tailored based upon one or more conditions related to communications devices within the target alerting region. | 09-19-2013 |
20140038511 | GEOCAST-BASED SITUATION AWARENESS - Geocast-based situation awareness utilizing a scalable, distributed ad hoc geocast protocol as a communication primitive, may provide a field common operating picture (FCOP) for providing location tracking, movement history, telemetry, and messaging in near real time to all operators in a scenario. Information may be transferred using a query/response geocast message protocol. Caching on devices may be utilized to gain scalability. A query message may have a payload containing a type indication and a header containing a description of a geocast region of intended reception, which may comprise the monitored region, the location of the monitorer, or any appropriate combination thereof. Response messages may be sent from devices located in the monitored region to an area containing the location of the sender of a query. A response message may contain monitored information, such as current location, telemetry data, and/or recent movement history, or the like. | 02-06-2014 |
20140098686 | GEOCAST PROTOCOL FOR WIRELESS SENSOR NETWORK - A protocol for providing location-based communication services in wireless sensor networks utilizes dynamic selection of forwarding devices, dynamic forwarding decisions, and intelligent backoff. Dynamic selection of forwarding devices limits the number of transmissions by dynamically selecting the devices that forward a message. Dynamic forwarding decisions implement different heuristics for different devices. According to intelligent backoff, devices that are closer to a destination region backoff for a shorter period of time than those which are further away from the destination region. | 04-10-2014 |
20140161006 | Geocast-Based File Transfer - Geocast-based file transfer may be implemented via use of a Geocast File Transfer (GFT) protocol. A sending device may parse a file into multiple chunks. Respective multiple geocast packets comprising the chunks may be geocast. The sending device may geocast all packets sequentially. Upon geocasting all packets, the sending device may wait a predetermined amount of time. During the period of time, any receiving device that did not receive a chunk of the file may geocast a request for the missing chunk. Receiving devices also may wait various respective amounts of time before geocasting requests. Other receiving devices that may have missed a chunk may hear that the chunk it missed is being requested. And that device need not make a request for the chunk. Rather, that device may wait for the sending device to retransmit a geocast packet that contains the missing chunk. | 06-12-2014 |
20140247769 | MEDIA DISTRIBUTION VIA A SCALABLE AD HOC GEOGRAPHIC PROTOCOL - Media is distributed via a scalable ad hoc geographic routing/broadcast protocol. Media can be transmitted from a mobile device to a cluster of mobile devices that are geographically located in a particular region. Devices that are located between the source and the intended target can act as routers with the ability to forward data packets toward the intended destination. In essence, a geocast network cloud is established, allowing any device within the cloud to communicate with any other device in the cloud. Devices in the network can constantly change position and the transmission path through the network can be constantly changing. The geocast protocol adapts to the changing conditions. | 09-04-2014 |
