Among such efforts, architecture-centric solutions with explicit representation of feedback loops have currently been advocated as a promising research landscape. Although noteworthy results have been achieved on some fronts, the lack of systematic representations of architectural knowledge and effective support for well-informed trade-off decisions still poses significant challenges when designing modern self-adaptive systems. In this paper, we present a systematic and flexible representation of design dimensions related to feedback control concerns, a set of metrics which estimate quality attributes of resulting automated designs, and a search-based approach to find out a set of Pareto-optimal candidate architectures. The proposed approach has been fully implemented in a supporting tool and a case study with a self-adaptive cloud computing environment has been undertaken. The results indicate that our approach effectively captures the most prominent degrees of freedom when designing self-adaptive systems, helps to elicit effective subtle designs, and provides useful support for early analysis of trade-off decisions.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"40 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":"116808121","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 goal can be accomplished by sharing device resources using their built-in WiFi adapter. In this paper we explain why the standard ad-hoc mode for building mobile peer-to-peer networks is not always the best choice and we propose an alternative self-organizing approach in which an opportunistic infrastructure-mode WiFi network is built. The particularity of this network is that each device can either be an access point or a client and change its role and wireless channel over time. This contribution advances the state of the art by using a context-aware approach that considers actual frequency allocation to other devices and monitored traffic. We finally show that our approach increases the average speed for delivering messages to a level that in several situations outperforms previous work in the area, as well as a simple single-channel ad-hoc WiFi network.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"27 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":"132617557","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}

On the other hand, a core problem to cope with in STM deals with (dynamically) regulating the degree of concurrency, in order to deliver optimal performance. We address this problem by proposing a self-regulation approach of the concurrency level, which relies on a parametric analytical performance model aimed at predicting the scalability of the STM application as a function of the actual workload profile. The regulation scheme allows achieving optimal performance during the whole lifetime of the application via dynamic change of the number of concurrent threads according to the predictions by the model. The latter is customized for a specific application/platform through regression analysis, which is based on a lightweight sampling phase. We also present a real implementation of the model-based concurrency self-regulation architecture integrated within the open source TinySTM framework, and an experimental study based on standard STM benchmark applications.","PeriodicalId":441278,"journal":{"name":"2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems","volume":"190 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":"125842800","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}

Cognitive heuristics are the mental models used in cognitive psychology to describe how human brains efficiently process the huge amount of information constantly coming from the environment around us. As personal mobile devices represent proxies in the cyber world of their human users, we investigate how the same cognitive heuristics can be used by mobile devices to become self-aware of the features of the physical environment around their users. Specifically, we assume that physical locations are described as a network of tags. We consider a self-organising opportunistic network environment, where devices exchange information when meeting directly. We propose algorithms based on cognitive heuristics through which users' nodes obtain tags either directly when coming in proximity of locations, or indirectly through other nodes they meet. We analyse the properties of the networks of tags resulting at individual nodes, as they emerge from this process, as a function of various cognitive parameters. We show that using cognitive heuristics leads, under the same resource constraints, to much more effective information diffusion with respect to other reference solutions. Interestingly, we find critical thresholds for key parameters that discriminate between information diffusion and information loss. Finally, we show that, despite resource constraints, the structure of the network of tags at individual nodes is remarkably close to the ideal that would be obtained with infinite resources.","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":"129430789","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}

A smart grid is a fully automated electricity network, which monitors and controls all its elements being able to supply energy in an efficient and reliable way. Within this context, the use of electric vehicles (EVs) and Vehicle-To-Grid (V2G) technologies have been advocated as an efficient way to reduce the intermittent supply associated with renewable energy sources. However, operating on V2G sessions in a cost effective way is not a trivial task for EVs. To address this problem, the formation of coalitions among EVs has been proposed as a mean to improve profitability on V2G sessions. Addressing these scenarios, in this paper we introduce the Self-Adapting Coalition Formation (SACF) method, which is a local and dynamic heuristic-based mechanism for coalition structure generation. In our approach, coalitions are formed observing constraints imposed by the grid to the EVs, which negotiate locally the formation of feasible coalitions among themselves. Based on experiments, we see that SACF is an efficient method, providing good solutions in a simple and low-cost way. SACF is faster than centralized methods and provides solutions with near optimal quality. In dynamic scenarios, SACF also shows very good results, being able to keep the agents gain relatively stable along time, even in quickly changing environments. Its main advantage is that the computational effort is very low, while classical centralized methods are limited to manage no more than a dozen agents in a reasonable amount of time.","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":"125819403","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}
