The key two steps of positioning in wireless systems are inference the accurate distance from the received signal strength indication (RSSI), and computing accurate location information from the inferred distance. The noise and multi-paths of the wireless channel will lead to complex nonlinearity relationship between RSSI and distance, which is difficult to modeled directly by the simple functions. Back Propagation (BP) neural networks can be used to construct ranging models with RSSI, but it will easily fall into local optimization which will lead to inaccurate. Besides, the MinMax localization algorithm used in the computing location information is easily affected by the fluctuation of the range value then will affect the localization accuracy. In this paper, a combined dynamic adaptive sparrow search (DASSA) with two-step residual network optimized MinMax (TSRK-MinMax) algorithm is proposed to improve the accuracy of beacon indoor localization. First, we use a dynamic adaptive sparrow search (DASSA) algorithm to optimize BP neural network to improve the ranging accuracy. Next, we utilize a K-Nearest Neighbor(KNN) algorithm to select the base stations which can receive the best signal. Then a two-step residual network are used to optimized MinMax algorithm (TSRK-MinMax) which leads to accuracy localization. The experimental results show that the overall localization error is reduced by 11.7%, which effectively improves the accuracy and robustness of the Beacon indoor localization.","PeriodicalId":251734,"journal":{"name":"2022 3rd International Conference on Computing, Networks and Internet of Things (CNIOT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133096071","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 order to meet the quality of service (QoS) requirements and save communication bandwidth at the same time, the technique of non-orthogonal multiple access (NOMA) is adopted. For practical purposes, we consider the case where each NOMA group consists of at most two PMUs. The problem is formulated as minimizing the required communication bandwidth while satisfying the observability constraint of the power grid, over all possible NOMA user pairing strategies, bandwidth allocation among NOMA groups, power allocation within each NOMA group and the normalized QoS exponents of each PMU. In order to solve this problem, we first derive the closed-form expressions of the effective capacity of the two-PMU NOMA pair, then the problem is solved by first fixing the NOMA user pairing strategy and the probability of successful transmission of each PMU, and finding the optimal bandwidth allocation among NOMA groups, power allocation within each NOMA group and the normalized QoS exponents of each PMU via the bisection search method. Then, the probability of successful transmission of each PMU is found via the simulated annealing algorithm for a fixed NOMA user pairing strategy. Finally, we discuss the benefit of using uniform channel gain difference (UCGD) pairing as the PMU-pairing strategy. Numerical results on the IEEE 14-bus power system demonstrate the significant bandwidth savings of the proposed algorithm compared with the orthogonal multiple access (OMA) method and the NOMA method with equal bandwidth and power allocation.","PeriodicalId":251734,"journal":{"name":"2022 3rd International Conference on Computing, Networks and Internet of Things (CNIOT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134014673","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 support of the hybrid transaction, blockchain oracle is an indispensable middleware responsible for receiving data-request tasks and pushing the result back to chain. Though solutions supporting hybrid transactions do exist, they are less featured or applicable for both contract and application developers. On one hand, the racing-condition among several concurrent hybrid transactions should be manually resolved by contract developers. On the other hand, application developers have to associate each individual task with its parent hybrid transaction in order to obtain the result. In this paper, a novel block-chain oracle platform with a set of simple but unified API for both hybrid and traditional transactions is proposed. Firstly, we design and implement a transactional storage layer and a transaction scheduler for transaction preservation and ordering. Secondly, with the help of an automatic result tracing mechanism, application developers are able to acquire transaction results transparently without awareness of oracles and underlying task execution. Experiments are conducted on one of current prevalent permissioned blockchain platforms, RepChain, and the result shows that all of the system design goals are fulfilled with merely an acceptable loss of performance.","PeriodicalId":251734,"journal":{"name":"2022 3rd International Conference on Computing, Networks and Internet of Things (CNIOT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131866265","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}
