Top-level operational view of multiple maritime sensors networked together and monitored and controlled from a single ground station. (Carlsbad, California), envision using marine sensing and networking technology to develop and demonstrate an integrated system that will provide more effcient and comprehensive harbor security. A key challenge facing maritime security operations is the lack of real-time communications capability to provide operators and decision makers with real-time domain awareness and command and control. In addition, any single user or organization responsible for security may be challenged to marshal the proper resources to provide a complete security solution. The sensor and platform technologies required to obtain relevant and actionable information exist. The organization and transfer of the information is the technical solution that has yet to be realized, and connection is the focus problem. L-3 PHOTONICS is developing the capability to link these many platforms, sensors and communication systems together in a cooperative manner in the waterborne surveillance and protection network (WaSPNet). WaSPNet's ultimate mission is to provide total maritime domain awareness for U.S. ports, harbors and waterways. Ad Hoc Network Support for ISR A swarm of autonomous and semiautonomous platforms [unmanned surface vehicles (USVs), UUVs and unmanned aerial systems (UASs)] communicate with each other and with other undersea or above-water fxed sensor systems. By working cooperatively, the systems can provide the information needed to protect critical infrastructure without impeding the normal fow of traffc, which is critical to adoption of 18 st / November 2013 any security procedure. The ultimate goal of this network is to operate seamlessly on, above and below the ocean's surface, relaying near real-time data and command and control capability to operators at a local ground station, and eventually to remote decision makers. L-3 PHOTONICS WaSPNet will provide a dynamically confgurable ad hoc mesh network to support the complicated intelligence, surveillance and reconnaissance (ISR) mission represented in ports and harbors. WaSPNet comprises a swarm of mobile and fxed network members. Each swarm member can operate as a node in the ad-hoc network. The nodes are then confgured (both in their capabilities and in their physical location) as needed to respond to changes in the operating theater. Since the swarm is intended to work in a maritime environment, each swarm member was developed with the appropriate level of environmental protection. At base, WaSPNet provides an extended local area network (LAN) or wide area network (WAN) capability via communications to the mobile swarm members. For this study, L-3 PHOTONICS implemented a gigabit Ethernet LAN to communicate with the various sensors, imagers and remotely piloted vehicles. The physical components of the LAN included wired and free space optical (FSO) communications links supporting the full 1 gigabit per second bandwidth, as well as radio frequency (RF) communications links with bandwidths to 20 megabits per second. At a top-level operational view, many different sensors, across many different platforms (USV, UUV, UAV, manned systems and fxed sensors such as Battelle's Harbor Shield, NUWC's CASMS or camera monitoring systems), are all networked into a single, fexible, mobile sensing environment. These many sensor data feeds are monitored and controlled via a combined operating picture software application by
