ZRP

• The ZRP is developed on top of AODV and OLSR.
• New version of AODV (v0.8) has been updated into
  the framework (better performance).
• To finalise and test.

Service Discovery

• Implemented the node classification for the nodes
  that will create the service discovery backbone.
• Integrate reactive service discovery mechanism
  implemented using AODV extensions for service
  discovery (Manage AODV service queries)
• To establish link state using OLSR
• To define service information as part of OLSR
  link state data.

6
Node classification

• During this period we have implemented the node
  classification (i.e. smart, dummy nodes) for
  creating Ad Hoc backbone.
• To analyse the creation of backbone as part of
  fixed infrastructure.

7
Applications

• The main task during last period was to test
  voice sessions in the Ad Hoc framework.
• To finalise
• 2) Light-weight SIP stack under development
• Binary around 1Mb versus 5Mb of ready made Vovida
  stack
• Possibility to modify the media transport to
  improve performance in multi-hop Ad Hoc networks.

8
VoIP session testing

• Complete further testing with new scenarios
  (multihop)

10
Further work

• Finalise tests on VoIP with new scenarios.
• Finalise existing routing modules (i.e. ZRP)
• Create an Ad Hoc network based on groups of smart
  nodes that will create an ad hoc backbone
• Finalise the service discovery module (reactive
  service queries from dummy nodes and proactive
  service information exchange between smart
  nodes).
• Complete the light-weight SIP stack under
  development with QoS optimisation.
• Test and bug fixing.
