Autonomous Undersea Systems Network (AUSNET)

Permission Not Granted
State: Maine

Technology Systems, Inc.'s research and development led to the creation of an advanced capability for operating ad-hoc networks in a low bandwidth undersea environment. The application supports Autonomous Undersea Systems Networks (AUSNET), fleets of unmanned robotic vehicles that can conduct survey, search, and monitoring activities for the oil industry, environmental management, undersea communications infrastructure, search and rescue, and military applications.  AUSNET has been demonstrated to support undersea ad-hoc networking with increased performance achieved through the exploitation of AUV fleet behaviors and the dead reckoning of node locations. 

The AUSNET protocol was developed to provide an ad-hoc network capability that was tailored for the low bandwidth undersea environment.  AUSNET has modified the DSR (Dynamic Source Routing) protocol by optimizing it for undersea operation. Each network node is capable of acting as a network router, so all network infrastructures is inherent in the AUV fleet. The network grows or collapses as nodes join or leave.  It is self-healing and supports entirely ad-hoc topologies.  By exploiting fleet behaviors, overhead has been significantly reduced. The expertise developed under AUSNET is also being applied to other projects including UAV video distribution, cooperative unmanned surface vehicle systems, and multi platform unmanned systems mission planning systems.
