Orc has been proposed as an elegant and more abstract design language. But much of its elegance derives from its functional style which must be matched, by the Software Engineer, with the state-based nature of systems as a whole. This pa- per explores the interface between the state-based and functional views of orchestration by studying an abstract, specification-oriented, semantics for Orc. Sound laws are established and the formalism used on simple examples to demonstrate the top-down development of implementations.","PeriodicalId":296445,"journal":{"name":"2010 International Conference on Communications and Mobile Computing","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133610639","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 order to improve the performance of location distinction in noisy environment, we propose a novel method based on ordinal pattern measure. The existing methods, such as channel gains of multi-tonal probes, received signals strength and temporal impulse response, take rare consideration on the impact of noise at the receiver. We evaluate the above methods in the noisy environment and find dramatic performance degradation in low SNR situation. We use a 2.4 GHz link measure data set, obtained from CRAWDAD [1], and find that the ordinal pattern method significantly reduces the false alarm rate in the noisy environment, in comparison to the original temporal impulse response method.","PeriodicalId":296445,"journal":{"name":"2010 International Conference on Communications and Mobile Computing","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133675396","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}

Because the best time to rescue in these heavy disasters can be predicted, the network lifetime can be expected. According to this feature, this paper proposes a multipath routing algorithm for WMSNs. Firstly, a set of node-disjoint routing paths is found by the method similar to a mazing search algorithm to reduce the number of energy consumption gathering nodes and high risk nodes of network congestion. At the same time, it is easy to support hole-bypass for the nature feature of a mazing search algorithm. Then, a multipath selection strategy is introduced. It employs a new type of congestion control message, a gradual increase strategy based on a path and a gradual increase strategy based on a flow to balance load and energy. These systems integrating the algorithm can maximize the data gathering performance.","PeriodicalId":296445,"journal":{"name":"2010 International Conference on Communications and Mobile Computing","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117217415","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}

Unfortunately, most approaches presenting loss problem are based on the approximates of the buffer overflow probability, which have been shown incorrect in most of time. Recently, network calculus has been widely used to obtain the performance bounds in QoS analysis, and a deterministic result for loss bound has been proposed. Different from previous research, this paper wants to emphasize the importance of stochastic probability in the study of loss bound. The loss issue is examined from a envelop process perspective and a stochastic loss bound with moment generating function are obtained finally.

Clustering is an effective method to reduce energy consumption of sensor nodes. In this paper we propose a cell base clustering algorithm. The target field is divided into small non-overlapping cells. Sensor node set in each cell is a cluster. The size of cell is well selected so that any node in adjacent cell can communicate with each other. We also present a low-overhead cluster head electing algorithm and an optimal inter-clustering routing algorithm. We evaluate the performance of our proposed clustering algorithm with comparing to GAF algorithm. The numbers of clusters generated by the two algorithms are approximately equal. But the average length of inter-cluster communication path of our proposed algorithm is less than GAF algorithm. So the network lifetime by our proposed algorithm is longer.","PeriodicalId":296445,"journal":{"name":"2010 International Conference on Communications and Mobile Computing","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134311796","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}
