IDRA: a novel protocol architecturefor networked embedded devicesEli De PoorterSupervisor(s): Ingrid MoermanI. INTRODUCTIONAn increasing amount of every-day objectsare equipped with (wireless) communicationtechnologies, from wireless media centers tocheap embedded sensor devices. Connectivitybetween these devices enables new marketableapplications such as wireless industrial processcontrol, wireless building automation, medi-cal monitoring, disaster intervention and au-tomated asset tracking. However, due to costrestrictions, ultra-low-cost embedded devicesdo not have enough processing power and/ormemory to implement a complex IP protocolstack.Figure 1. In a wireless building automation applica-tion, embedded devices automatically connectto each other to regulate household functions.II. ENABLING NEXT-GENERATIONAPPLICATIONSOur IDRA protocol architecture [1], [2]is designed specifically to cope with theseresource-constrained devices and their net-working challenges:—————————————————–E. De Poorter is with the Department of Informa-tion Technology (INTEC) of Ghent University• Reduced hardware cost. The IDRA com-munication stack requires only 27kB ROM and3kB RAM.•High performance and a low energy foot-print. IDRA reduces the energy consumptionby combining multiple information exchangesinto a single packet. In addition, IDRA has in-built provisions for quality-of-service.• Backwards compatible. Legacy protocolsare selected automatically when communica-tion with legacy devices is required.• Intelligent protocol selection. Based on theapplication requirements, an intelligent serviceselector dynamically activates the most appro-priate network protocols from those availableon each device.• Always-best-connected. When communi-cating, the optimal packet format, network pro-tocols and communication interface are auto-matically selected based on the cost and/or per-formance preferences of the IDRA user.A. ConclusionsIDRA allows the development of net-worked next-generation applications on em-bedded (sensor) devices. The architecture isavailable as an open-source communication ar-chitecture [3], either under the GPLv2 licenseor under custom commercial license.REFERENCES[1] E. De Poorter & I.
