Abstract

In future large-scale Emergency Response/Management (ER/EM) to terrorism and natural disasters, sharing the so-called common operational picture amongst dynamic task groups provides immediate advantages. In an ER/EM scenario, dissemination of the right data to the right person at the right time has a direct benefit. Timely and bandwidth efficient dissemination of sensor and Command and Control data remains a challenge. For example, dynamically changing mobile teams, information-needs profiling, information routing based upon information needs (not on IP address) are all complex issues. Accordingly, a protocol, called dissemination mesh, for constructing and reconfiguring network paths for disseminating information from sources to sinks, a software architecture for multi-domain wireless network information dissemination in the context of emergency response (resting above existing MANET protocols), supports needs-based dissemination, node mobility, rapidly changing groups (information sinks) and sensor networks (sources) is provided. The protocol includes: exploitation of Semantic Web and collaborative agent technologies, novel subscription-based information dissemination, intelligent networked information intermediaries, smart dissemination mesh forming and management. Together these technologies provide information dissemination management in the wireless setting. Application realms other than ER/EM can also be supported.

Claims

1. An architecture for information management and delivery in peer-to-peer mobile ad hoc networks comprising:

at least one source node;

at least one sink node;

at least one dissemination server (DS); and

intelligent agents which configure source nodes, sink nodes, and DSs in a domain and reconfigures any source node, sink node and DS entering the domain so that information traveling from a source node to a sink node traversing the DS continues towards the sink node as a source node, sink node and DS enter and exit domains.

2. A method for managing and delivering information in peer-to-peer mobile ad hoc networks comprising the steps of:

configuring each source node, sink node and dissemination server (DS) in a first domain;

reconfiguring any source node, sink node and DS entering the first domain or leaving the first domain to a second domain; and

forwarding information from a DS in the first domain toward a reconfigured sink node in the second domain.
