Communication Networks

SiENA provides four different communication networks out of the box.

  1. Wired broadband (DSL-like)
  2. LTE
  3. PLC
  4. BRITE

Households and servers communicate with each other via the communication network. A communication link is an IP-based socket, based on UDP or TCP.

General Parameters:

  • Network
  • TCP or UDP
  • Duplicate package check

Wired broadband

tree

The wired broadband communication network resembles a tree topology. Households and servers are connected in random groups to the bottom layer of a tree of routers.

Parameters:

  • Cluster size: 10
  • Household/server data rate: 5 Mbps
  • Household/server delay: 20 ms
  • Router data rate: 1 Gbps
  • Router delay: 2 ms
  • Tree layers: 3, between root node and households

LTE

tree

In the LTE topology households and servers are placed randomly in groups around a LTE mast.

Parameters:

  • Nodes per enb node: 250
  • Max distance to enb node: 500 m
  • Distance between enb nodes: 1000000 m
  • Delay min: 5000 ms
  • Delay max: 10000 ms
  • Minimum random placement angle: 0
  • Maximum random placement angle: 3.1415
  • random function: SQRT
  • Download: 100
  • Upload: 100

PLC

tree

The PLC topology resembles a main street with access roads. The plc-module offers many parameters, which are initialised corresponding to the PRIME standard, which offers 128.6 kbps in the CENELEC-A band.

Parameters:

  • Residents in a main street: 100
  • Residents in an access road: 10
  • A lot of stuff related to PRIME

BRITE

tree

The BRITE topology creates a large representative topology of the Internet. Households and servers are connected to outer nodes. A standard config file of the BRITE tool can be used for configuration.
