A Real‐Time and Low Power Working Method for Mobile WSN
Xiaotong Du, Wei Zhang, Dong Li · Mathematical Problems in Engineering · 2014
In many mobile wireless sensor network (WSN) applications, the low power problem is often ignored to maintain the real‐time property of monitoring nodes. To solve the long‐time working problems of mobile nodes and the whole WSN network, this paper provides a new working method. First, the real‐time and consumption features are compared between the Random Mechanism (RM) and Time‐Division Mechanism (TDM) through experiments. Secondly, a mobile Time‐Division Mechanism based on subnet node ID is designed to reduce the power consumption on the premise of real‐time requirements effectively. At the same time, relevant experimental results demonstrate that time synchronization mechanism cannot improve the real‐time performance effectively.
