Coordinator assignment scheme and routing algorithm for wireless sensor and actuator networks

摘要

Since WSAN is a type of WSN, it has the same problems occurring in WSN such as energy problem as well as other issues caused by connecting sensors and actuators as a network. There have been many researches to resolve those problems. However they are still not enough to apply to real world building control systems and home automation systems since those researches only consider networks composed of one type of sensor and its corresponding actuator. This paper proposes a method applicable even in case of networks consisting of many types of actuators and sensors. For the purpose a routing algorithm is also proposed to assign actuators as coordinators by locations and to satisfy real time characteristic needed in WSAN.
