Conventional approaches largely ignore the temporal aspects of node-to-node connectivity, and perform an offline analysis. In this paper, we characterize the temporal connectivity in a mobile wireless network, in a decentralized manner. We present Path Detect, a distributed algorithm that combines local broadcast with distributed consensus to achieve a spatial-temporal view of network connectivity. Additionally, the information gathered by Path Detect allows for the distributed computation of temporal efficiency, a metric that has until now only been computed centrally. Path Detect is adaptive, and can therefore track connectivity changes in real-time. We evaluate Path Detect under diverse test-cases featuring node and wireless link failures, and mobility patterns. Through these evaluations, we show that the comparison of Path Detect against the ground truth observation shows less than 10% relative error in estimation of temporal efficiency for most cases. Additionally, we also present our results of evaluating Path Detect on a real-wold network, showing that it is an attractive choice for real-world implementations.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130414067","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 talk will then present these mechanisms under the form of design patterns, detailing what problem they address and what solution they provide. The second part of this tutorial focuses on showing how an application can be designed and engineered taking into account these design patterns. We will present three different execution models: rule-based systems, fraglets and BIO-CORE and discuss how they accommodate the design patterns discuss in the first part. In particular we will expand on BIO-CORE, an execution model that provides basic bio-inspired mechanisms as built-in services and allows the system to execute several composed or top-level bio-inspired mechanism at the same time, all sharing the basic mechanisms implemented inside the core. Finally, we will present open challenges in the area of engineering self-organizing systems, regarding the use of basic design patterns as operators ready-to-use that applications and services can rely on.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129989292","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}

These difficulties promote a self-organizing solution for the problem of time synchronization in WSNs to be quite desirable. Current self-organizing time synchronization protocols in WSNs have drawbacks: They either provide synchronicity but not a common notion of time for the nodes in the network or they demand keeping track of the time information of the neighboring nodes. The latter drawback becomes quite crucial especially on dense WSNs, which makes available self-organizing time synchronization protocols impractical. This paper provides a novel self-organizing time synchronization protocol for WSNs which does not require keeping track of the neighboring nodes. The main component of our protocol is a computationally light \"adaptive-value tracking\" algorithm which synchronizes the rate of each sensor node to that of all its neighboring nodes through successive feedbacks. We show by simulations that the proposed protocol achieves a tight synchronization which results in the desired property of global time notion after a finite amount of time on dense networks. Although there is no formal proof yet of the protocol's convergence, we anticipate this protocol could be used as a practical time synchronization approach.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127974560","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 presents an improvement of the state of the art for multi-threaded pipe-and-filter processing architectures. We present a novel approach for adapting the time of data generation in the pipeline where adjacent pipeline stages exchange information about the current utilization. We compare our approach to a traditional input data driven pipeline and achieve a significant reduction of the processing delay and required memory consumption. The improvement of the presented system is based on self-adapting the data generation rate in the processing pipeline. This adaptation results in two key efficiency improvements: (i) the reduction of the time data elements spend in the pipeline and (ii) the reduction of the memory requirement for communication buffers. These improvements are of special interest for reactive and interactive multi-camera applications where short delays of the image processing pipelines is often required. The presented approach enables any data-flow based application to execute with reduced memory usage, reduced execution delay and the highest possible data-rate.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121960500","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}

Specifically, we compare previously known homogeneous configurations, when all cameras use the same marketing strategy, with heterogeneous configurations, when each camera makes use of its own, possibly different marketing strategy. Our first contribution is to establish that such heterogeneity of marketing strategies can lead to system wide outcomes which are Pareto superior when compared to those possible in homogeneous configurations. However, since the particular configuration required to lead to Pareto efficiency in a given scenario will not be known in advance, our second contribution is to show how online learning of marketing strategies at the individual camera level can lead to high performing heterogeneous configurations from the system point of view, extending the Pareto front when compared to the homogeneous case. Our third contribution is to show that in many cases, the dynamic behaviour resulting from online learning leads to global outcomes which extend the Pareto front even when compared to static heterogeneous configurations. Our evaluation considers results obtained from an open source simulation package as well as data from a network of real cameras.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114163438","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}
