Service DiscoveryService DiscoveryService DiscoveryService 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.

Node classificationNode classificationNode classificationNode 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.

• 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.

Further work:Further work:Further work: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.
