HENCSAT created a test bed for application of Network Coding to heterogeneous satellite based communication networks. This is relevant since satellite communication increasingly is used as a complementary addition to other radio communication solutions, and there is an opportunity to combine all, rather than select one, or multiple networks.
As about 70% of all Internet traffic is video, HENCSAT is particularly including video and photo communication. Since satellite networks commonly are used for mission-critical communication the focus is further on use of visual communication for information and situational awareness purposes.
Users are expected to be mobile, and networks are assumed to be changing as a function of time and location. Links are expected to have errors and traffic is assumed to be IP-based.
HENCSAT specifically targeted two concreate objectives that were modelled and generalized to cover a broader scope:
In this project, several key challenges were identified to deliver reliable visual-data communications with network coding:
In addition to these challenges the right test bench design was a general challenge.
The HENCSAT test bench helped users find solutions that provide better capabilities for critical services over heterogeneous networks that include satellite. Novel innovation beyond state-of-the-art for satellite networking was created that opens up for exploitation of new and powerful services.
Later solutions based on HENCSAT will be able to create product far beyond current state of the art, and position Europe as leading innovator in the relevant satellite networking areas.
HENCSAT solutions increased user experience for visual communications when satellite-links are use in the access domain for either sender, receiver or both sides, for a wide range of applications such as:
The novel technologies are implemented in a testbed, and the key benefits are verified. The technologies are ready to explore further and take to a products phase, potentially flown in a UAV.
Main Features of HENCSAT:
Selected non-exclusive use Case Scenarios:
While the challenges are complex, the basic system architecture is relatively simple:
The two scenarios are interconnected in the top drawing of this web page.
The duration of the project was 18 scheduled for months.
The basic planning is shown below.
The kick-off of the project was 1st October 2016.
The project is on completed.
