摘要:
Vehicle-to-vehicle and vehicle-to-infrastructure communications are accomplished via a scalable ad hoc geographic routing protocol. As vehicles move along roadways, they can query other vehicles and entities for information. Responses to queries can be used to determine information such as traffic conditions, a retail store sale, that a restaurant has tables available, and/or that parking spaces are available, for example. Businesses, vehicles, and other entities along roadways can geocast pertinent information to vehicles passing by. Vehicles can cache information as it is received.

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.

A first iterative Grover Search process is performed by causing at least one quantum computer to perform a first series of Grover Searches according to a characteristic function for varying numbers of iterations to identify a first search target. The characteristic function is modified according to the identified first search target. A second iterative Grover Search process is performed by causing the at least one quantum computer to perform a second series of Grover Searches according to the modified characteristic function beginning with a number of iterations determined based on a number of iterations required for at least one prior iterative Grover Search process to identify a second search target.

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.

A method is disclosed for initiating real-time geo-game using geocast messaging according to a scalable tiered geocast protocol. The method includes a first wireless terminal (WT), programmed with a geo-gaming application and the scalable tiered geocast protocol, geocasting a game declaration to a destination geocast region containing potential participants. The method also includes a second WT, of one of the potential participants, and programmed with the geo-gaming application and the scalable tiered geocast protocol, receiving the game declaration in the destination geocast region and responding by geocasting a response message indicating interest in participating in the real-time geo-game.
摘要:
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.
