The International Symposium on Networks, Computers and Communications (ISNCC)

The next edition of the International Symposium on Networks, Computers and Communications (ISNCC) will be held at our university from June 19th to June 21st 2018.

It is a medium-sized conference that was held in North Africa in the previous four editions. The conference is technically sponsored by IEEE and is indexed in IEEE Xplore, Scopus, DBLP and Thomson Reuters (Web of Science).
Prof. Michele Luglio was appointed as general co-chair.
The honorary chairman of the conference is Mr Enrico Russo, CTO of the Italian Space Agency (ASI).
The call for paper in pdf can be downloaded here while the home page is http://www.isncc-conf.org where it is possible to find any other information about topics, tracks, committees etc.

Simulation and Emulation Tools

10.12.2011 · Posted in Late News

Analysis of the systems and related protocols involved in the previous projects, as well as tests on the possible

enhancements, have been carried out by SMG group through two different test platforms:

  • a satellite network simulator based on the Network Simulator Ns-2;
  • a Linux-based emulator platform.

Both the platforms support DVB-RCS DAMA algorithms and are alternatively used depending on the objective of the study case and are described in the following documents:

 

Satellite Emulator

11.02.2010 · Posted in Laboratory, Late News

Satellite Multimedia Group has developed several tools to support studies related to satellite communications. A detailed description of both such tools and some related research activities can be found here >>>>SMG tools<<<<

The group is developing a satellite simulator composed of 5 PC to study applications and transport protocols in an emulated satellite environment.

The figure below shows details about the satellite emulator:

dsc_0223

Every PC emulates a single component of a tipical satellite environment VSAT, with DVB-RCS or terrestrial return channel. In particular, pc are involved in:

  1. Gateway/HUB
  2. Satellite
  3. Satellite terminal (i.e. modem)
  4. User terminal (i.e. client FTP and HTTP)

Figure, shows the pc’s logical interconnections:

DAMA DVB-RCS NS2 patch

09.02.2010 · Posted in Laboratory, Late News


DAMA DVB-RCS NS2 patch available
To apply on latest ns-2.32 version, it makes possible to test TCP connections behavior in simulated DVB-RCS environment with a DAMA shared return channel. Satellite Terminals can be configured so that capacity is requested with CRA, RBDC and VBDC (also mixed) strategies, up to the system capacity.

Return channel is composed of a single carrier divided temporally into frames. A group of frame, each one composed of a constant number of slots, make a superframe. A slot is the minimum amount of capacity allocated to a terminal.
