| 概要 | In a wireless sensor and actor network (WSAN), a group of sensors and actors are geographically distributed and linked by wireless networks. Sensors gather information sensed for an event occurring in the physical world and send them to actors. Actors can perform appropriate actions by making a decision on receipt of sensed information from sensors. Sensors are low cost, low powered devices with limited energy, computation, and wireless communication capabilities. Sensors may not only stop by fault but also suffer from arbitrary faults. Furthermore, wireless communication is less reliable due to noise and shortage of power of sensors. Reliable real time communication among sensors and actors is in nature required in WSAN applications. In order to realize the reliability and realtimeness, we newly propose a multi-actor/multi-sensor (MAS) model where each sensor in an event area sends sensed information to multiple actors and each actor receives sensed information from multiple sensors. Actors are required to causally and totally order sensed information and actions. In this paper, we discuss how to realize reliable, causally/totally ordered delivery of sensed information and actions with realtime constraints. |
