A Context Interpretation Based Wireless Sensor Network for the Emergency Preparedness Class of Applications

摘要: Emergency Preparedness is one of the most appealing classes applications for context-aware wireless sensor networks (WSN). In such environments, contexts can be captured and interpreted in WSN application layer to help preventing, fighting, rescuing checking against fire, explosions, leaking toxic gases etc. this paper, we show a Wireless Actor Sensor Network (WASN) that used interpret simple complex contexts. We present an efficient technique make use actors aggregate events, eliminate ambiguities redundancy realize context interpretations. Each actor WASN configured with rules are determined by network configuration phase. Context information exchanged among sink(s) through publish/subscribe paradigm based on specific topics. set simulation experiments evaluate performance our protocols networks.
