Distribution of Multicast DNS Messages over an OLSR Wireless Mesh Network

Note: this thesis is no longer available as it is,

a first version has been implemented by Saverio Proto and it has been merged in the official olsrd distribution see here for source code:  http://olsr.org

Description

In a wireless mesh network, the usage of wireless interfaces in ad-hoc mode and the OLSR routing protocol prevent multicast messages to be distributed all over the network.

We are especially interested in the distribution of Multicast DNS (mDNS) messages, used for host-based service discovery, over the networks that do not directly partecipate in the OLSR mesh cloud.

This task may be achieved in the following way:

  1. the local router picks up from the local non-OLSR (HNA) network mDNS messages and encapsulates them in a new type of OLSR messages,
  2. the OLSR infrastructure is exploited for the transport of these messages,
  3. remote routers decapsulate mDNS messages from received OLSR messages and send them over their attached non-OLSR networks.

The work could have its practical and immediate application in all the wireless network communities that employ the OLSR protocol.

The main idea is to implement a OLSRd plugin to transport mDNS traffic.
