Considering privacy concerns of enterprises, blockchain and federated learning architecture become an effective solution. However, this solution cannot avoid malicious training behaviors of enterprises in order to obtain high profits, resulting in the degradation of global model performance. To cope with the problems above, this paper proposes a local model quality control method based on credit mortgage value. Specifically, each enterprise submits a portion of its credit value as a credit mortgage to participate in federated learning, then each enterprise obtains rewards or penalties according to the quality of the enterprises local model combined with the credit mortgage value. Simulation results show that our method can improve the performance of the global model with malicious behavior on the clients. For example, when the malicious training probability of the client increases to 30%, the credit mortgage value required by the client to participate in federated learning becomes 6.2 times the original value, and revenues turn to be negative. Severe negative revenues can form an effective control over the quality of the local model. So our method can realize effective control of local model Quality.","PeriodicalId":357138,"journal":{"name":"2022 IEEE 42nd International Conference on Distributed Computing Systems Workshops (ICDCSW)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115307573","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 looks at how bandwidth incentive encourages peers to share bandwidth and rewards them for their contribution. With the advent of blockchain technology, many p2p networks attempt to reward contributions by crypto-assets. We conduct simulations to better understand current incentive mechanisms, assess the fairness of these mechanisms, and to look for ways to make those incentives more equitable. The following are the primary contributions of this study: (i) We investigate and simulate bandwidth incentives within Swarm, a cutting-edge p2p storage network; (ii) We demonstrate one approach to make the current bandwidth incentives more equitable; (iii) We use the Gini coefficient to define two quantifiable fairness characteristics to evaluate reward sharing in a decentralized p2p storage network.","PeriodicalId":357138,"journal":{"name":"2022 IEEE 42nd International Conference on Distributed Computing Systems Workshops (ICDCSW)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125202126","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}

Although existing works focused on the safety of pedestrians, the safety of personal- mobility vehicles is what smart cities need to address toward the future. On-board sensors could be easily disabled because of external issues of hardware caused by dirt or snow, internal issues of hardware, and software issues such as malware infection. We propose an edge computing system that supports robust vehicle automation with a sensor network using multiple light-detection- and-ranging (LIDAR) sensors deployed like roadside cameras or indoor security cameras for surveillance for personal-mobility vehicles. We develop a prototype system of the proposed system using real LIDAR units and a mobility scooter and evaluate the system in terms of route errors to verify the feasibility of the proposed system with a scenario where the vehicle is enabled to continue self-driving even when its on-board sensor is disabled.","PeriodicalId":357138,"journal":{"name":"2022 IEEE 42nd International Conference on Distributed Computing Systems Workshops (ICDCSW)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129793005","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, transmitting the huge volume of the generated visual data through the meandering terrestrial networks would overwhelm the backbone networks and cause non-negligible latency. Mega-constellations, such as OneWeb and Starlink, is developing as one of “New Infrastructure Construction”, and could provide high-capacity and low-latency communication in a world-wide range. However, most of the existing mega-constellation networks' topology is fixed and would easily fall into congestion with the bursting traffic generated by the large-scale telepresence applications. To address this challenge, we propose a reconfigurable mega-constellation architecture by utilizing the permanent and temporary laser inter-satellite links (LISLs). Moreover, based on the mixed-integer linear programming (MILP), we design a routing system, FlyLISL, aiming at balancing the global traffic load by minimizing the maximum link utilization of all LISLs. To evaluate the effectiveness of FlyLISL, we simulate the performance of FlyLISL by comparing with the particle swarm optimization (PSO) and Random based routing strategies. Compared with reference works, FlyLISL reduces the maximum link utilization by up to 72.6%.","PeriodicalId":357138,"journal":{"name":"2022 IEEE 42nd International Conference on Distributed Computing Systems Workshops (ICDCSW)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130299569","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 Software-Defined Wide Area Networks (SD-WANs), the controller dynamically routes flows from metaverse applications to maintain good performance by sending control messages to underlying switches. Thus, the control latency between controllers and switches for rerouting flows is one critical factor for metaverse's performance. However, existing works may introduce high control latency between switches and controllers since they do not consider the dynamic state of each switch in the real world situation. In this paper, we propose to optimize the control latency in SD-WANs by solving a critical programmability-aware problem. Inspired by critical flows, which have a critical impact on network performance, our proposed solution considers the programmability of critical flows at switches to decide the placement of controllers and mapping between switches and controllers. Simulation results show that our work can reduce the control latency by up to 27.5% compared with the baseline algorithms.","PeriodicalId":357138,"journal":{"name":"2022 IEEE 42nd International Conference on Distributed Computing Systems Workshops (ICDCSW)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124196301","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 the event of a natural disaster, the time lag of satellite data availability, and the scarcity of hazard sensing and rescue resources become major obstacles. We believe motivating social and stakeholders engagement will help improve the resilience capacity against disasters, minimizing the impact of uncertainties of disasters, and allowing hazard management systems to make efficient allocation of rescue resources (e.g., first responders) and relocation plans. In this paper we propose a novel, efficient, effective, economical, and sustainable approach, which exploits resources and data from stakeholders (e.g., citizens, infrastructure managers, authorities, rescuers, NGOs, urban and land-use planners) to tackle the intrinsic uncertainty in the nature environment and the human society. This approach will help forming a new understanding and exploitation of stakeholder resources to reduce risks, provide quick responses, exploit scarce resources, save more lives, assist reliefs and beyond.

An economical and insightful way to study the use of UAV s in cities is through the utilization of computer simulations. However, currently available simulators are only of limited use to investigate such scenarios: often they have been developed for a dedicated use case, can only handle single UAV s, or the software was not made available with an open license. In this paper, we present AirMobiSim, a modular and microscopic UAV simulation framework, which is available under a GPLv2 license. AirMobiSim provides the basis for the creation of kinematic and energy models for different UAV types. It can support an arbitrary number of UAV s and can be coupled with other simulators via open interfaces, for example to examine systems using wireless communication between UAVs. We furthermore present our approach for model-building and show that AirMobiSim can already accurately reproduce existing work. We also highlight current limitations and show prospects for future work.","PeriodicalId":357138,"journal":{"name":"2022 IEEE 42nd International Conference on Distributed Computing Systems Workshops (ICDCSW)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130053732","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 most relevant drawback is the high latency, meaning a connection that does not require a reliable delivery can use UDP, another transport layer protocol, slimmer than TCP, which provides a connectionless datagram service prioritizing time over reliability. During these years, researchers have worked on new protocols in the attempt of decreasing page load time without sacrificing reliability. Even Google proposed a solution, the Quick UDP Internet Connection (QUIC) protocol, born in 2013. Since QUIC is a very recent protocol, this paper could help to further understanding its employment and performance in typical scenarios such as, for instance, when considering major social networks such as Facebook and Twitter, with only the former employing QUIC. In particular, we have measured the response time of the two applications when considering different network conditions. Our preliminary results could be used to generate traffic models and, partially, to advocate the use of QUIC.","PeriodicalId":357138,"journal":{"name":"2022 IEEE 42nd International Conference on Distributed Computing Systems Workshops (ICDCSW)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130766695","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}
