IoT solutions can be very complex with respect to multiple technologies that need to work together to bring data from sensors in field to applications on phone and cloud. Without data flowing reliably across the multiple hops there is no IoT solution. IoT bench marking solution is an advanced software package that measures performance of the solution components like IoT Platform, IoT gateways and smart sensors to identify performance bottlenecks, data black-holes and stability issues of an IoT solution. The solution has a built in sensor simulator that simulates various sensors and data types to help validate the solution before a real , at scale deployments to significantly reduce risk with rolling out a complex solution.
