What is CAMOS?

CAMOS (Coastal and Arctic Maritime Operations and Surveillance) is a strategic research areas at the Faculty of Information Technology, Mathematics and Electrical Engineering (IME).

The aim of the strategic research area is to accelerate the development of the high level research activity within costal and maritime operations at NTNU, supporting and initiating new collaboration initiatives within IME technology areas. CAMOS is a framework for cooperation with both industry and international partners.

Background

Activities in the northern regions operate in an extreme and challenging environment that includes coastal, marine, and arctic areas. With the exception of coastal areas these offer little permanent infrastructure, let alone ground to build it on, and little use of communication infrastructure solutions utilized elsewhere.

As coverage from geostationary satellites do not reach north of Svalbard, new solutions to provide communication support to operations in remote locations must be found. Simultaneously, some of the operations are wholly or partially undertaken underwater, requiring solutions that reach and integrate both over and underwater operations.

The strategic research area takes on the ambitious task of developing a robust integrated communication framework that encompass underwater, terrestrial radio and satellite communications in a resilient infrastructure that can support a multitude of applications, primarily within sensor networking. The goal is to provide a platform to enable the integration of new and improved technologies in any part of the system with ease – fostering innovation within the system. This is the communication backbone and structure of an integrated arctic observation sytem.

Challenges

The arctic regions have enormous potential with corresponding great challenges. Some operational challenges in the Arctic include:

  • monitoring of ice features and drift
  • environmental monitoring
    • oil spills and of their spreading
  • basic traffic and operations monitoring
  • research infrastructure and instrumentation of the Arctic ocean
    • marine bioresources
    • climate

 

These types of operations require communication support to connect with an operations center. The challenges to provide this support include lack of infrastructure in vast areas, and little coverage by geostationary satellites.

The foreseeable elements of a communication system include a combination of acoustic underwater communications, terrestrial/marine radio and satellite radio. Underwater transmitters, buoys, ships, land based base stations, satellites and mobile (underwater, surface, airborne) unmanned vehicles make up the nodes of the communication network.

A communication network built of these elements faces a few fundamental problems including intermittent availability of mobile nodes and satellites, and variability of communication medium, and respectively application related performance requirements.

Activities

The project's main activities:

1. Robust and efficient networking in dynamic heterogeneous environments. This task will study robust and cost-efficient network architectures providing communication between heterogeneous nodes in CAMOS sensor networks. The Department of Telematics is the main responsible for this activity.

2. Mission and path optimization for mobile sensor network operations. This task will study highlevel mission and path planning for coordination of mobile sensor network operations, including deployment and motion. The activity is housed by the Department of Engineering Cybernetics.

3. Using micro-satellites as network nodes. This subproject will put emphasis on study and design of network of small satellites for uploading and downloading of data from sensors. The satellites will operate as a part of the sensor network, and provide basic communications coverage, especially where such is not available otherwise. The activity is at the Department of Electronics and Telecommunication.

4. Underwater communication. Emphasis on acoustic communication and the challenges of acoustic propagation in arctic waters. Studies of the topology of the underwater sensor network and the communication links to the surface. The activity is at the Department of Electronics and Telecommunication.
