Smart objects need to be accessible and usable by ordinary users through familiar software and access technologies to facilitate any interaction and to increase their acceptance rate. This work deals with a seamless integration, discovery, and employment of smart objects into the Internet infrastructure under Human-to-Machine (H2M) communication aspects. We introduce an XMPP-based service provisioning sublayer for the IoT to integrate resource constrained devices seamlessly into the Internet by showing how XMPP can empower the collaboration between humans and smart objects. To meet the requirements of constrained devices, we propose to extend XMPP's publish-subscribe capabilities with a topic-based filter mechanism to effectively reduce the number of exchanged XMPP messages. We further present standardized bootstrapping and handling processes for smart objects that adapt automatically to infrastructure and ad hoc network environments and do not require predefined parameters or user interaction. The applicability of XMPP for constrained devices is further demonstrated with an XMPP client and mDNS/DNS-SD service for the Contiki operating system.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116346837","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}

However in such networks, not all nodes are reliable. Therefore it may be necessary for legitimate users to monitor the behavior of other nodes such that they can form a belief about whether those nodes are potential attackers or not. These beliefs can be studied precisely in game theoretic scenarios such as Bayesian attacker detection games. These games are strategic games with incomplete information for modeling the interaction between nodes in wireless networks with channel uncertainty. However these games do not normally consider the reasoning abilities of agents. One solution is to use formal logics which allow for modeling the reasoning abilities of agents as well as allowing formal reasoning about certain properties of games such as the Nash equilibrium. In this paper, we propose an epistemic logic to study strategic games with incomplete information. In this logic we can precisely describe what the requirements and consequences of informative actions are. We can reason what rational agents should do if they can choose between different available actions. In addition, this language can be used as a semantically well-defined query language for model checkers to automatically verify the game descriptions with respect to their intended specifications.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130927207","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 such systems, in-network data processing presents high efficiency for energy and bandwidth, but unfortunately introduces several challenges related to data security and fault tolerance. In this paper, we present and analyze a new protocol that allows for confidentiality-preserving in-network aggregation for collaborative WSNs in the face of intermittent link-level failures. Our protocol makes use of a symmetric-key, homomorphic cryptosystem to maintain the confidentiality of individual sensor readings while still permitting a trusted sink node to recover the correct aggregate value. The encrypted sensor readings are then combined using a multipath aggregation protocol that is capable of detecting and recovering from a variety of failure scenarios while carefully handling duplicate sensitive aggregates. We prove the security and correctness of our protocol, and we conduct simulation studies to understand its data transmission and energy consumption overheads. Our results show that both confidentiality and fault tolerance can be achieved in representative network configurations, while incurring an increase of 7.1 % in the average message size and 3.6% in the average energy consumption. In the unlikely scenario that 100% of the sensor nodes participate in an aggregate query, the average energy consumption showed at most a 25% increase.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126184246","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 question that receives far less attention is that of Collaborative analysis of Big Data; how can a multi-disciplinary layered analysis of Big Data be used to support robust decisions, especially in a collaborative setting, and especially under time pressure? The robust Decision Engineering required can be achieved by employing an approach related to Network Science, that we call Relationship Science. In Relationship Science, our methodological framework, karassian netchain analysis (KNA), is utilized to ascertain islands of stability or positive influence dominating sets (PIDS), so that a form of annealed resiliency or latent stability is achieved, thereby mitigating against unintended consequences, elements of instability, and “perfect storm” crises lurking within the network.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128063283","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}

For modeling such partner interactions as flow of message exchanges, different top-down approaches, covered under the term interaction modeling, are provided. Like for workflow models, correctness constitutes a fundamental challenge for interaction models; e.g., to ensure the boundedness and absence of deadlocks and lifelocks. Due to their distributed execution, in addition, interaction models should be message-deterministic and realizable, i.e., the same conversation (i.e. sequence of messages) should always lead to the same result, and it should be ensured that partners always have enough information about the messages they must or may send in a given context. So far, most existing approaches have addressed correctness of interaction models without explicitly considering the data exchanged through messages and used for routing decisions. However, data support is crucial for collaborative workflows and interaction models respectively. This paper enriches interaction models with the data perspective. In particular, it defines the behavior of data-aware interaction models based on Data-Aware Interaction Nets, which use elements of both Interaction Petri Nets and Workflow Nets with Data. Finally, formal correctness criteria for Data-Aware Interaction Nets are derived, guaranteeing the boundedness and absence of deadlocks and lifelocks, and ensuring message-determinism as well as realizability.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130221987","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}

Reputation-based approaches depend on the users local experiences and feedback to create a soft measure for trust decision. They use various clues and past experience to decide on taking the risk of dealing with an entity. Reputation communities cannot exchange reputation or reputation information following an isolated-silos approach. The reasons for this varies from missing contexts in the reputation representations and heterogeneity in these representations, to technical reasons such as not being represented in an interoperable knowledge representation method. Developing interoperable reputation ontologies requires a technology that can provide means of integrating data sources and methods to relate the data to its explicit semantics. In this paper, we describe our design decisions in developing our reputation object (RO) ontology using semantic web technologies. The main motivation that leads these decision is to facilitate reputation information exchange or reputation interoperability along with model expressivity. Therefore, choosing the ontology language and specific APIs is explained in relation to this motivation.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116222592","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}

However, there remain challenges due to limitations in available mobile hardware and software capable of managing resource intensive applications. This paper addresses the issues related specifically to concurrency control improvement in mobile web servers. We propose a Dynamic Resource Management Strategy (DRMS), which uses an asynchronous based approach to reduce the number of discarded incoming client requests by a mobile web server. The DRMS strategy includes identifying the incoming heavy requests from the clients, which require relatively heavy system resources on the mobile server to generate a response, and adding those requests to a heap for them to be processed asynchronously. Based on I-Jetty we designed and developed Dynamo, an implementation of DRMS, for Android-based mobile devices. We conducted an experimental study on Dynamo. Our results demonstrated the effectiveness of DRMS with the improvement in Dynamo's concurrency control management as compared to the same in I-Jetty.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132907652","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}
