The sensor node in such network is a battery-operated sensing device. These nodes are placed in space with a consideration to a base station that centralizes and consolidates the data transmitted or forwarded by sensor nodes. When optimizing the management of a Wireless Sensor Network, we have to take care of the consumption of energy that takes place while sensor nodes are running the routing process to send or relay a message to neighbors or to a Base Station. In this paper, we put forward a study of sensors' behavior by modeling and implementing a controller with Coloured Petri Network in order to ensure the reduction of energy consumption in some sensor networks in which each node can be activated or suspended as need be. The controller must deal with activation and suspension to apply a reconfiguring policy to nodes depending on an energy supply level in every sensor in order to obtain the lowest level possible of energy consumption and maintain the same service quality consisting in total coverage of the region to survey and the connection of active nodes to the functional network. The evaluation of our presented model is made by CPN-Tools.","PeriodicalId":423978,"journal":{"name":"5th International Conference on Design & Technology of Integrated Systems in Nanoscale Era","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123845658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can be viewed as a set of synchronized tasks, communicating and sharing critical resources. One of the main difficulties in the real-time application design is time constraints meeting. All tasks have to be running before their predefined deadlines. At this level, the integration of real time operating systems (RTOS) in the real-time systems design flow is necessary to enable scheduling tasks and managing the competition between them with respect of timing constraints. One of the problems encountered here is that one task may have different execution times. It may exceed its predefined WCET and then its deadline for many reasons. The problem is that one deadline exceeding may cause subsequent constraints violations which may disrupt the functioning of the system. This paper deals with this particular issue. It presents a new technique that permits the monitoring of tasks under execution. It controls their timing constraints by means of watchdog concept and detects deadline missing. That information is used to tune the target application parameters in order to satisfy timing constraints for the further computation iterations. We have implemented this technique in the RTOS MicroC/OS-II using the EDF scheduling policy. This technique has been validated using an Altera FPGA prototyping platform and the 3D rendering application.","PeriodicalId":423978,"journal":{"name":"5th International Conference on Design & Technology of Integrated Systems in Nanoscale Era","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127708947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
