==Click==

Tried to implement an element by polymorphy (a diamon), which is possible in C++. But it did not worked in Click. Maybe someone has a working example. I tried virtual and so on, but it did not compile. I use the delegation pattern instead, which is also ugly, since I need to pass the set ports.

ExOR

  • entgegengesetzt zu Network Coding, denn ich weiß nicht, wer das Paket bekommen wird (aber aus der Menge meiner Nachbarn)
  • verwende nur Broadcasts und der Knoten am nächsten zum Ziel leitet das Paket weiter (Problem, wenn das Netz voll ist; Broadcasts "zerstören" sich gegenseitig oder erweitertes RTS/CTS?)
  • dichte Netze als Vorraussetzung
  • Verwendung mehrerer Kanäle um "Self-Interference" zu vermeiden (oder erweitertes RTS/CTS?)

Using the LEDs of wgt634u


Routing in wireless Networks Things to consider

  • Negative effects
    • self interference
  • Postive effects
    • Broadcast nature

Ideas:

  • Minimizing transmissions (Network Coding / ExOR)
  • Minimizing collisions (difficult)

Routingprotokolle aus Nachrichtensicht Layer 3 - Flooding - Multicast - Unicast

Layer 2 - Broadcast (lokal) - Multicast - Unicast

Die Idee ist, dass alle Routingprotokolle Nachrichten versenden müssen. In diese Nachrichten-Elemente steckt man dann nur noch den Payload.

Kann man das Routing auch adressunabhängig implementieren (mittels Polymorphie)

=> Besseres Engineering
