ABSTRACT
This chapter provides an overview of industrial application classes and requirements as well as the design requirements and challenges that must be considered when developing any routing mechanism in wireless embedded monitoring and control networks for industrial environments. It provides a survey on existing approaches for routing in industrial environments as well as mechanisms that may be employed to provide Quality of Service (QoS) at the routing level. Routing is a key process in wireless sensor networks (WSNs) when dealing with QoS requirements as routing decisions impact on network lifetime, packet delivery ratios, and end-to-end delays. The ROLL group focuses on analyzing the functional requirements for routing protocols in industrial Low-power and Lossy Networks, which include industrial WSNs. The ROLL working group classifies applications depending on the type of traffic they generate as: periodic data, event data, client/server data, and bulk transfer data.
