The Service Level Agreements are well-known in Web Services and Cloud Computing. The development of the IoT paradigm, leading to dense radio environments, particularly in cities, brings the necessity of sharing wireless sensor & actuator network infrastructure. At the same time, IoT applications have more and more stringent requirements in terms of the QoS the WSN can support. The cost of deployment and maintenance drives the market toward shared infrastructures that maximize the revenue of the telco operator.

We propose to extend a SLA framework for managing WSANs.

SLAs consist in the formal specification of the required services of a final customer and the corresponding contractual clauses that both operator and customer agree to follow. In order to give guarantees for the applications, the operator first needs to decompose the SLA into network parameters, in order to allow the admission control of the new flows. Then, it requires resource allocation mechanisms, to give each customer the necessary communication opportunities, with minimal waste of bandwidth. And finally, the operator needs a precise enough monitoring of the infrastructure, in order to supervise the contracted network performances, and the clients requirements. The network monitoring and control loop remains challenging for future IoT deployments.
