Enabling resource sharing in heterogeneous wireless sensor networks

Wireless Sensor Networks (WSNs) are trending towards environments comprised of multiple parties owning many devices. In this environment, node owners want to share their sensor nodes' limited resources, but need to be able to limit resource access and to charge for the resource usage. Node users need to handle the complexity of deploying functionality on very heterogeneous networks. Current WSN approaches enable building large scale applications, yet often ignore node heterogeneity or assume a single party owns and manages the network. This paper proposes three contributions: 1) a resource modeling language, 2) a system architecture and 3) a tool for assisted and validated application planning and deployment across heterogeneous networks. A prototype shows the feasibility and illustrates the opportunities of controlled sharing of node services.status: publishe
