Common use of Configuration Management Clause in Contracts

Configuration Management. In wireless networks, the broadcasting nature of the channel mandates that the nodes control their transmissions in order to avoid collisions or inter- xxxxxxx. In WSNs, one can schedule the communi- cations, according to algorithms such as the Traffic- Aware Scheduling Algorithm (TASA) [10], which uses matching and coloring heuristics to find a commu- nication solution, given the nodes topology and the required traffic load. In WSNs, radio link quality estimation is crucial to predict if the agreed-upon QoS will be met [3]. It permits, alongside with other raw measures (e.g. re- maining energy of the nodes [8], traffic statistics), to elaborate the composite metrics defined in the SLOs. Some of these metrics prove that the QoS require- ment of each SLO is met, and guide the real-time control actions on the network. Others are defined as Key Performance Indicators (KPIs), and sent to the clients and the WSN operator to show them high level statistics of the network. The communication protocols for WSNs have for long been studied and implemented with the goal of meeting QoS constraints. A classification of the MAC layer mechanisms is proposed in [17]. At the routing layer, the IETF ROLL RPL [15] proposes the construction of the routing topology based on Objective Functions (OFs). The OFs include QoS constraints that the topology must meet at buildup. IETF CORE CoAP [11] is an application level proto- col based on UDP and adapted for constrained nodes. WSN Operator Finally, one may design WSNs applicative behavior in order to provide easier resource allocation for con- current applications [8].
