Data packets are forwarded toward the destination, and nodes, which hear the packet compete for becoming the next hop. A recovery strategy is provided for the case of empty forwarding areas. The main innovation is a strategy to avoid simultaneous forwarding situations, which would otherwise cause packet failures. It is confirmed by simulation that BGR sends very few packets and is reliable infields with sufficiently high node density. Furthermore, BGR is compared with similar algorithms after developing a general framework for beacon-less algorithms with an integrative terminology. Different kinds of forwarding areas are compared.","PeriodicalId":266947,"journal":{"name":"Third International Workshop on Intelligent Solutions in Embedded Systems, 2005.","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125051157","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}

The first approach is based on a high priority thread and the second one on a local advanced programmable interrupt controller (LAPIC). Robustness was evaluated on unloaded and loaded system. In order to assess real-time system performance we analyzed sampling time histograms and maximum timing error. Both approaches perform satisfactory on unloaded system. On loaded system LAPIC approach shows better robustness. Although sampling time histograms show bigger errors on loaded systems than on unloaded systems, maximum timing error does not change significantly for the LAPIC approach.","PeriodicalId":266947,"journal":{"name":"Third International Workshop on Intelligent Solutions in Embedded Systems, 2005.","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123922712","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}

In our work, which is motivated by the potential of implementing our prototype by MEMS technology, we got inspiration from the polarization of vision, which is found in some insects for location detection. The polarization vision in some insects enables them to navigate by the so-called polar compass, which is based on the polarization pattern of the sky. In our work, first we investigate a polar compass, then use this polar compass to determine the location, where more than one source is available by measuring the angles of all of the sources. Our experimental result proves the feasibility of our low cost, compact and integratable prototype to measure the angular displacement.","PeriodicalId":266947,"journal":{"name":"Third International Workshop on Intelligent Solutions in Embedded Systems, 2005.","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115585871","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}

This paper deals with scheduling periodic real-time tasks to such an architecture, a problem which has not been considered before. We formalize the real-time scheduling problem and propose two preemptive scheduling algorithms. The first is an adaption of the well-known earliest deadline first (EDF) technique to the FPGA execution model. The algorithm reveals good scheduling performance; task sets with system utilizations of up to 85% can be feasibly scheduled. However, the EDF approach is practical only for a small number of tasks, since there is no efficient schedulability test. The second algorithm uses the concept of servers that reserve area and execution time for other tasks. Tasks are successively merged into servers, which are then scheduled sequentially. While this method can only feasibly schedule task sets with a system utilization of up to some 50%, it is applicable to large tasks sets as the schedulability test runs in polynomial time. Equally important, the method requires only a small number of FPGA configurations which directly translates into reduced memory requirements.","PeriodicalId":266947,"journal":{"name":"Third International Workshop on Intelligent Solutions in Embedded Systems, 2005.","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127233488","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}

In a traditional RTCS, a set of tasks running in a central controller provide the required system control. The recent technological advances have made it possible to embed controllers with sufficient computing power directly in the end control devices. These devices also have a communication interface by means of which they can communicate with the other devices via a broadcast bus. These devices are referred to as intelligent nodes. A network of such intelligent nodes can be used to perform the same control functions as that of a centralized RTCS in a distributed manner. This paper discusses an application of a formal approach to distribute the control of a centralized RTCS over a set of intelligent nodes with an example.","PeriodicalId":266947,"journal":{"name":"Third International Workshop on Intelligent Solutions in Embedded Systems, 2005.","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133890225","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}

An integrated low-power analog/digital converter (ADC) is presented that is particularly suited for wireless sensor applications. The converter makes use of information theoretic redundancy in the input signal for reducing the conversion workload and performing data compression on-the-fly during conversion (entropy-coding A/D converter). Thus, energy is saved both in signal conversion and transmission. Experimental results from a prototype chip are presented. The converter is especially suitable for sensor networks that maintain a global data model. This is further illustrated on an exemplary scenario of distributed wave detection. It is shown that sensor signal detection and acquisition in this type of applications can be carried out very efficiently with entropy-coding converters used in the sensor nodes.","PeriodicalId":266947,"journal":{"name":"Third International Workshop on Intelligent Solutions in Embedded Systems, 2005.","volume":"53 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132973487","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}

Since our target platforms are distributed embedded systems with limited resources, the task allocation has to be light-weight, flexible as well as scalable and has to support real-time requirements. Therefore, surveillance tasks are not allocated to smart cameras directly, but to groups of smart cameras, so called surveillance clusters. We formulate the allocation problem as a distributed constraint satisfaction problem (DCSP) and present a distributed method for finding feasible allocations. Finally, a cost function is used to determine the optimal allocation of tasks. We have realized this dynamic task allocation using heterogeneous, mobile agents, which utilize their agencies and our embedded software framework to find the most appropriate mapping of tasks in a distributed manner. The dynamic task allocation has been implemented on our smart cameras (SmartCam), which are comprised of a network processor and several digital signal processors (DSPs) and provide a complex software framework.","PeriodicalId":266947,"journal":{"name":"Third International Workshop on Intelligent Solutions in Embedded Systems, 2005.","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127769863","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}
