Abstract: Embodiments relate to method products for publishing messages within a geographic area. Aspects include receiving a location from each of a plurality of user devices and creating a geo-hash tree based on the location of each of a plurality of user devices. Aspects also include receiving a message with the geographic area, computing a geo-hash grid for a region that includes the geographic area and identifying one or more nodes of the geo-hash tree that corresponds to the geo-hash grid. Aspects further include transmitting the message to one or more of the plurality of user devices associated with the one or more identified nodes.

Abstract: A method, system and computer program product for dynamically routing messages in a publish/subscribe system. A messaging application receives messages from sensors (e.g., road condition sensors). Upon analyzing the messages using data analytics, an event (e.g., icy road condition) may be correlated with the analyzed messages. In such a scenario, a temporal topic based on the triggered event is created. Furthermore, a temporal publication (e.g., “icy road condition near exit 40”) and a temporal subscription are created. Potential subscribers to be associated with the temporal subscription are identified by using either geo-location information or social media information. Once those subscribers are identified, they are associated with the temporal subscription. The temporal publication is then published to the subscribers associated with the temporal subscription.

Abstract: Content of a publish-subscribe topic tree is provided. This includes receiving a path for a requested topic. The path specifies topics leading from a highest to a lowest level topic in the path. Content in the topic tree is retrieved for matching topics that match the lowest level topic in the path independently of whether the matching topics are on the path in the tree.
