Validating the sensor network calculus by simulations
For example, in industrial wireless sensor networks, sensor data must be transmitted to their destination before a deadline; otherwise, terrible disasters may happen.
In this paper, we present a multimode wireless sensor network model and extend the network calculus to multimode networks.We propose two methods to compute the maximum delay bound of the flow of interest and discuss which one of the methods has the tighter delay bound.Experiments show that our proposed methods are effective and scalable.The rest of paper is organized as follows: Section 2 introduces the related work. Section 4 describes our multimode wireless sensor networks. The related work is classified into the following two categories: the analysis of networks and the analysis of multimode embedded systems.Section 5 introduces our proposed end-to-end delay bound analysis methods and the corresponding comparative analysis. Schmitt and Roedig present a series of works on the analysis of sensor networks.
