Geo-fencing involves a location-aware device of a location-based service user or asset entering or exiting a virtual area. Rather than geofences being static, in indoor positioning systems they need to be dynamically updated, frequently, efficiently and on-demand. Furthermore, the underlying geofencing framework must work to incorporate the changes in the systemÂŠs operational context (signal obstruction, static and dynamic obstacles, etc.) and compensate for their influence on the location calculations. In this paper, we propose the Geofencing Micro-location Asset Tracking (GEMAT) framework for dynamic security geofencing management and notification/actuation based on the Bluetooth Low Energy Micro-location Asset Tracking (BLEMAT) IoT system. We show how an indoor geofencing framework that includes and compensates for contextual updates provides more functional geofencing capabilities, both in terms of precision and sophisticated use cases. We present the main functionalities of the geofencing framework and test them in a real-world IoT environment. Furthermore, we elaborate on a performance analysis model for geofencing frameworks with ten criteria defined. Conducted experiments and performance analysis show that the proposed GEMAT framework is a good candidate for solving problems in a wide range of indoor geofencing use cases.","PeriodicalId":126836,"journal":{"name":"Proceedings of the 9th Balkan Conference on Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129501740","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 swarm scenarios where the concept for the teams of robots requires performing cooperative tasks, robots need to be enforced to communicate with each other in the background while executing specific collaborative missions. In order to achieve complex tasks in real-time beyond their individual capability, multi-robot systems (MRS) require a stable, sustained and secure stream of data exchange. Typically, this technique also requires an approach of communication and synchronization among the robots known as swarm R2R (robot to robot) communication in real time [1]. This paper presents a theoretical concept for a wireless mesh robot network that can be protected against electromagnetic interference (EMI), electromagnetic jamming, RF denial-of-service (DoS) attacks, and eavesdropping. The team behind this paper aims to present and propose a conceptual model for a hybrid short-range modular wireless transceiver (HSMWT) used in a distributed network environment. Specific issues on designing HSMWT based on the light and sound mediums for this environment will be explored.","PeriodicalId":126836,"journal":{"name":"Proceedings of the 9th Balkan Conference on Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125667492","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}

Nowadays, there exists another hash algorithms family -- SHA3(SHA-3), which includes SHA3-256 and SHA3-512 algorithms, also known as Keccak algorithms. This paper provides a comparison of the empirical performance calculations with these 4 algorithms with different input volumes of sequential data (where every next slice of information is dependent of previous one) to make it impossible for parallel computation. For the purpose of calculations, 4 totally different environments are used but with exact number of CPUs and approximately similar amount of memory (using only standard instances types) -- one personal computer from one side and 3 of the biggest public cloud providers from another -- Amazon AWS (t2.medium), Microsoft Azure (Standard D2s v3) and Google Cloud (n1-standard-2). The purpose of the research is to compare these environments in terms of additional compute calculations and additional storage space (volumes and prices) for the presented new security improvement of the Merkle-root calculation. The Merkle-root is an integral part of the blockchain and therefore, security improvement of this component is a security improvement of the whole blockchain structure.","PeriodicalId":126836,"journal":{"name":"Proceedings of the 9th Balkan Conference on Informatics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126953873","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}
