Schedulability Analysis and Performance Evaluation of WSAN

The current trend in the development of Networked Control Systems (NCS) is the use of wireless networks to communicate the system nodes, which have been called Wireless Sensors and Actuators Networks (WSAN). This trend is principally to increase flexibility and reliability of these applications and to reduce the implementation cost. Several protocols have been used, however the latency and jitter presented in the transmission period produce that not always a similarity between experimental and simulation results can be obtained. This is because imprecise models for analyzing and designing these systems are used, and to make use of inadequate validation methods and platforms that do not support the models utilized. Therefore this paper presents a method to analyze end – to – end schedulability of WSAN, and evaluate the performance of case study using Medium Access Control (MAC) algorithms TDMA and CSMA – CA .
