General

What is mesh networking?

Why mesh networking?

Benefits of mesh networking

  • self organizing
  • low system maintenance needed
  • robust due dynamic route recalculation

Disadvantages of mesh networking

  • additional network traffic

OLSR

General

[OLSR] is a dynamic linkstate Protocol which collects link data and dynamically calculates the best routes within the network.
