A mobile ad hoc network consists of wireless hosts that may move often. Movement of hosts results in a change in routes, requiring some mechanism for determining new routes. Several routing protocols have already been proposed for ad hoc networks. This report suggests an approach to utilize location information (for instance, obtained using the global positioning system) to improve performance of routing protocols for ad hoc networks.

Vehicular networking has significant potential to enable diverse applications associated with traffic safety, traffic efficiency and infotainment. In this survey and tutorial paper we introduce the basic characteristics of vehicular networks, provide an overview of applications and associated requirements, along with challenges and their proposed solutions. In addition, we provide an overview of the current and past major ITS programs and projects in the USA, Japan and Europe. Moreover, vehicular networking architectures and protocol suites employed in such programs and projects in USA, Japan and Europe are discussed.

Vehicular Networking: A Survey and Tutorial on Requirements, Architectures, Challenges, Standards and Solutions

A mobile ad hoc network consists of wireless hosts that may move often. Movement of hosts results in a change in routes, requiring some mechanism for determining new routes. Several routing protocols have already been proposed for ad hoc networks. This paper suggests an approach to utilize location information (for instance, obtained using the global positioning system) to improve performance of routing protocols for ad hoc networks. By using location information, the proposed Location‐Aided Routing (LAR) protocols limit the search for a new route to a smaller “request zone” of the ad hoc network. This results in a significant reduction in the number of routing messages. We present two algorithms to determine the request zone, and also suggest potential optimizations to our algorithms.

A concept-based indexing and search system indexes collections of documents with ontology-based predicate structures through automated and/or human-assisted methods. The system extracts the concepts behind user queries to return only those documents that match those concepts. The concept based search and retrieval system comprehends the intent behind a query from a user, and returns results matching that intent. The system can perform off-line searches for unanswered user queries and notify the user when a match is found.

Concept-based search and retrieval system

Methods and a system that provide a network of data sources in terms of a traditional database schema, convert traditional database queries into network messages, and route those messages to those data sources which have relevant data, in some instances through designated query nodes. In the present invention, those data sources accept the message, and then send reply messages to the originator of the query, or via designated join nodes in some embodiments. In some embodiments, the data sources may be able to perform local join operations. The system then collects these reply messages as appropriate at the designated join nodes, designated query nodes, and/or at the data sources, and the reply messages that meet the requirements of the query are sent back to the query originator. The query results provided to the query originator are presented as a traditional database result.

GPS-Based Addressing and Routing

Indexing and routing to event data is described. Event data is assigned an identifier that identifies the data type and the contents of event data within an enterprise system. The event data may be real-time event data. With the identifier, a source of the event data is determined, and the source can be queried for the event data in real-time. The identifier is indexed along with other event data identifiers. Based on the location of the event data, the system sends out a query toward the data source to obtain the information, but also to route the query to the data source, rather than attempting to pull data towards the query source and process it at the query source.

Intelligent event query publish and subscribe system

Parsing of event queries in an enterprise system is described. The enterprise system receives queries, which are broken down into query components. The query components each represent segments of the query. The enterprise system identifies sources of event data and sends queries towards the sources of the event data. The query components are processed close to the data source. The responses are combined to generate an event query response that indicates the event data of each of the query components.

Federating business event data within an enterprise network

Merging of query elements in an enterprise system is described. The enterprise system receives queries, which may each be broken down into query components. The enterprise system identifies query components that are related to identical event information from a data source of the enterprise. The enterprise system sends a single query to the data source for the event information, receives the response, and sends the response to the query sources.
