Objective: To develop methods, protocols and techniques to support streaming and event-based data in a heterogeneous sensor network.

This work package aims at developing efficient, robust and reliable communication protocols, which routes information between dynamic clusters being formed in the network by taking into account quality of service required by the application and resources available in the network. Routing protocols can be dynamically installed and adapted using the programming system of WP4.

Two cases are studied in particular:

• large linear structures of sensor nodes (LANE) as occurring, for example, in street lighting and pipeline monitoring (in accordance with the Philips Research use case; see WP1).
• clouds of smart sensor phones (CLOUD) with highly dynamic behavior and where nodes are heterogeneous and non-stable in terms of availability (in accordance with the VTS Politie NL use case; see WP1).

These network topologies are typical in the various application domains, and have different requirements and system characteristics. LANE and CLOUD networks will be able to interact and use each other's infrastructure in several ways. E.g., mobile phones are used as data mules to offload (stored) information from sensors in street lighting (as found in delay tolerant networks), or sensors in street lighting are used to augment mobile phone ensembles (see WP4). WP3 uses WP1 as input and its results are used in WP4 and 5.

• Task T3.1 Networking protocols for LANE wireless sensor networks (AS)
• Task T3.2 Opportunistic network protocols for participatory and opportunistic sensor nodes (UT/PS)
• Task T3.3 Integration of LANE wireless sensor networks and CLOUD smart sensor phone networks (UT/SAN)
