Abstract:
The issues in Wireless Sensor Networks (WSNs), are challenging as well as their applications demand for goodservices, distribution, modularity and intelligence. WSNs are characterized by varying software architectures, which hasled to the development of a plethora of WSN middlewares, management and reconfiguration protocols. To ensure thepotential of evolving WSN technologies and software architectures, it is required that the users can move away fromtraditional approaches towards an adaptable service oriented hybrid architecture, which should ideally run on the platefor wireless sensor devices, to minimize redundant protocol stack overhead. More importantly, the middleware shouldprovide distributed machine to machine communication and implementation level model driven architectures shoulddescribe how the WSN works at each level of the network. In our work we present the compelling arguments for this visionof future WSNs and demonstrates how some of these concepts have been implemented on a significantly large physicalWSN in NIMBUS Center of Embedded Systems Research Cork Ireland. Besides, this work provides an overview ofimplementation of the hybrid native architecture (HNA) on sensor devices and its collaborative functionality with a modelbased Open Framework Middleware (OFM) for WSN.
