COOJA and Testbed Federation/TWIST growing together

Two COOJA plugins and manuals have been published to integrate the TWIST testbed in COOJA and to take checkpoints and perform rollbacks both in TWIST and COOJA.


Call for Papers: CONET/UBICITEC 2013

Mobility SupportFixed nodes
Total Number of Supported Nodes28
Horizontal Node Spacing3
Vertical Node Spacing
Variability of Supported SUT PlatformsMultiple - heterogeneous SUT

Additional SUT PlatformTmote Sky
Number of Nodes from the Additional SUT Platform4
SUT SensorsNo sensing
SUT ActuatorsNo actuation
Power Supply of SUT NodesPower over USB
Control/Monitoring Plane SeparationOut-of-band (the control/monitoring plane uses separate medium/channel from the SUT)
Control/Monitoring Plane Communication TechnologiesUSB, Ethernet
Control/Monitoring Plane ArchitectureHierarchical and distributed (connection via set of secondary nodes / micro-servers which are then connected to the main "controlling" entity/server
Control/Monitoring Plane Gateway PlatformsCustom NSLU2
Job Execution ModelInteractive (direct user control over the job execution process)
Job ConcurrencyNo concurrency (single job in a given time slot), Concurrency per platform type (concurrent jobs have to use different SUT node platforms), Concurrency per node ID (concurrent jobs have to use different sets of node IDs)
Job Registration and Scheduling Interfacetext mode client
Authentication and Authorization Architecturemust be within the firewalls
Job Control InterfaceNo interactive job control
SUT Node Control ServicesPower cycling, Resetting, Image programming, Image erasing, Data collection, Power consumption monitoring
SUT Data AccessIndirect access to serial/secondary channel via client library APIs
SUT Data PersistenceNo persistence
Time Stamping ServicesDistributed time-stamping using time synchronized control/monitoring plane (time stamping at the micro-server/secondary node level that are globally synchronized using a service like NTP or FTSP)
Integration with Simulators and EmulatorsNo integration
Remote Use PolicyNo remote access
