Along with event detection, the event evolution is equally important. Most existing methods ignore the evolution of the events and further fails to identify the influential spreaders of that event. Moreover, for the impact of the continuous developing events, predicting the linkages with other premature events, will help in the domains of economy such as commodities and stock markets. Twitter is widely used as an effective source of data collection and provides unique keywords (hashtags). However, it does not provide insights about the trend which makes it difficult to detect events. The research experiment environment and preliminary results presented in this paper are currently based upon the Brexit’s historical dataset. However, we plan to define proper way to simultaneously snapshot whole dynamic dataset at different times and eventually use real-time data. Our motivation for the research is to develop a new data analytic system and supporting techniques to find events for enhancing the decision-making,,,, process.","PeriodicalId":414464,"journal":{"name":"2018 IEEE Symposium on Service-Oriented System Engineering (SOSE)","volume":"386 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124783340","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}

JCLedger is a blockchain based distributed ledger for JointCloud computing which can make cloud resources exchange more reliable and convenient, and it is the combination of JointCloud and BlockChain. One of the most important elements for creating JCLedger is the consensus algorithm. PoW (Proof of Work) is the consensus algorithm for Bitcoin, which is proved to be quite safe but needs much computing power. The original PoW is not suitable for JCLedger because the identities of participants are not equal in computing power, which may lead to accounting monopoly, and the throughput cannot satisfy the requirement of the massive and high-frequency transactions in JointCloud. In this paper, we propose a PoW based consensus algorithm called Proof of Participation and Fees (PoPF), which can save much computing power and handled transactions more efficiently for JCLedger. In our design, only the candidates have the opportunities for mining and the candidates are chosen according to the ranking which is determined by two factors: the times of the participant to be the accountant and the fees the participant has paid. The difficulty for candidates of solving the PoW hash puzzle is different (the higher ranking means easier for mining). The simulation experiment shows that the distribution of accountants is well-balanced, that is to say, the unequal computing power of participants in JointCloud is shielded, and all the users who have enough contribution in JCLedger will have the opportunities to be accountants.","PeriodicalId":414464,"journal":{"name":"2018 IEEE Symposium on Service-Oriented System Engineering (SOSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129033731","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 outstanding problem in this area is the availability of effective application-layer protocols between service seekers and providers at the Internet of Things (IoT) level because most IoT nodes run on batteries. Hence, IoT-Fog discovery service must be energy efficient to prolong the lifetime of smart objects. This paper presents a thorough study of our previously proposed MQTT-driven IoT-fog integration, namely the Power Efficient Node Discovery (PEND), and investigates the impact of dynamic arrival patterns on its performance. The MQTT broker serves as a fog node to trigger turning on/off the Bluetooth Low Energy (BLE) interfaces of the surrounding objects by monitoring their trajectories. Furthermore it leverages this additional location awareness to significantly reduce the power consumption of the device discovery process for mobile devices. With this motivation, we present a detailed performance study of PEND under various settings and provide in-depth discussions of some lessons about the obtainable energy saving and the effectiveness of the our enhanced BLE device discovery solution. The results we present are valuable for the fog community to design new optimizations and to refine the whole IoT device discovery process to the purpose of better efficiency and scalability.","PeriodicalId":414464,"journal":{"name":"2018 IEEE Symposium on Service-Oriented System Engineering (SOSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129474698","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 kind of communication blocks the consumer until the response arrives, and, besides, the invocation timeout can be reached raising a timeout error. Hence, an asynchronous call is more appropriate where the consumer calls the provider’s service and continues processing, and, when the provider’s service finishes it pushes the response to the consumer. There are different ways for implementing an asynchronous communication. A simple way is the consumer providing a callback function which the provider’s service invokes when it finishes the processing, performing a server push operation. However, there are many cases where this solution cannot be applied requiring other alternatives, e.g.: the consumer keeps up with the service execution checking for its readiness or state, and when it finishes, it calls another provider’s service to get the result; the consumer and provider keep an open connection for the asynchronous communication. This work analyzes the main server push technologies used for web development, presenting their weaknesses and strengths, and the existing main challenges. As a result, we provide a technologies comparison, and a classification based on multiple qualitative dimensions that helps one to choose the technology that fits its requirements and/or can be used to guide future researches in this field.","PeriodicalId":414464,"journal":{"name":"2018 IEEE Symposium on Service-Oriented System Engineering (SOSE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133405736","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, the commodity hypervisor usually has a considerable attack surface and its memory is especially prone to be tampered with by an attacker who resides in one VM and then threatens the security of other co-located VMs. To mitigate such threat, previous solutions proposed an out-of-the-box design which leverages the nested virtualization to introduce a higher privileged software layer (a nested hypervisor) below the hypervisor. It also installs a security monitor into a trusted VM which is protected by the nested hypervisor and isolated from the untrusted hypervisor. The monitor is responsible for dynamically validating the behaviors of the untrusted hypervisor. Although monitoring from outside of the hypervisor can help ensure security, the large number of context switches caused by the nested virtualization incurs unacceptable overheads and makes this approach unsuitable for the cloud environment. In this paper, we introduce In-Hypervisor Memory Introspection (IHMI), an in-the-box way to monitor the hypervisor based on the nested virtualization. Our system puts the monitor into the untrusted hypervisor for efficiency while guaranteeing the same level of memory security as monitoring the hypervisor from a separated secure VM. By leveraging hardware virtualization features of current processors, IHMI isolates the monitor from the hypervisor via the nested page table and implements an efficient switch between them. Further, IHMI configures a uni-directional mapping for the monitor which allows the monitor to access the hypervisor’s memory at native speed while forbidding the hypervisor from accessing the monitor’s memory. Our IHMI system is currently still in an early stage and we report our design as well as preliminary evaluation results in this paper.","PeriodicalId":414464,"journal":{"name":"2018 IEEE Symposium on Service-Oriented System Engineering (SOSE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131866515","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}
