A Petri-net Based Approach to Control the Information Access Procedure of Sensors in Distributed Wireless Sensor Network System
Distributed Wireless Sensor Network (DWSN), comprises of small sensor nodes with sensing, computation, and communication capabilities. Due to advancement in technology today's small and cheaper sensors are used for as sensing units for measurement of physical conditions in the people environment surrounding. These sensors convert the information into electrical signals. From these signals the processing unit reveals some properties about objects located or events happening in the vicinity of the sensors. Thousands of sensors are deployed in the sensory field to collect the information from particular place. Sensors send the information to the base station by coordinating among themselves.
