To exchange packets over an FCN, traffic load must be uniformly diffused to fully utilize its high bandwidth. As a method to do this, the rebalancing algorithm was proposed. Previous studies have demonstrated the effectiveness of the method through theoretical analysis and computer simulation. However, its practical feasibility has not been elucidated. Moreover, its performance has not been confirmed on a physical experimental environment. This paper reports how the rebalancing algorithm is implemented on switches built on PCs using software tools supported by the Linux OS. This confirms that it is relatively easy to practically implement the algorithm. In addition, the performance of the implemented algorithm was assessed and compared with that of a conventional method through an experiment. As a result, the rebalancing algorithm was found to be more advantageous in avoiding traffic congestion for heavy traffic and flows with different sizes.","PeriodicalId":205731,"journal":{"name":"2022 32nd International Telecommunication Networks and Applications Conference (ITNAC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114564148","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 investigations are made based on an optical intensity modulated band-limited DC-offset orthogonal frequency-division multiplexing (DCO-OFDM) system. Usually, the frequency-selective channel transfer function determines the bit allocation. In the present scenario, this approach must be adapted, because the clipping noise is distorted by the same channel as the information signal. Therefore, adaptive modulation can no longer achieve a gain when clipping becomes the dominating source of distortion. In this paper, the total signal-to-interference-and-noise power ratio (SINR), considering clipping noise at the transmitter and additive noise at the receiver, is calculated. Based on this result, the optimal bit allocation table (BAT) for each scenario, ranging from no clipping to very strong clipping, can be determined. It is shown that the error probability of a band-limited DCO-OFDM transmission can be approximately halved based on this concept. Additionally, the optimal transmit power to achieve the lowest error probability in a given system can be theoretically calculated. The results are verified by simulations.","PeriodicalId":205731,"journal":{"name":"2022 32nd International Telecommunication Networks and Applications Conference (ITNAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130571394","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 deployment of RSUs along the highways provide low-latency communication, suitable for applications where high-speed response is needed, such as autonomous driving and crash avoidance. These RSUs must be connected to the Internet through a high-bandwidth and reliable access network being the optical fiber technologies the most convenient technology for that. In this paper, we propose a planning scheme for enabling RSUs with optical access networks. The method starts choosing the locations of the access network headers (the connection points to the local service provider facilities), and then defines the connections between the headers and the RSUs in a convenient manner considering the road infrastructure. Then, two deployment technologies based on optical fibers are compared: Point to Point (P2P) and Passive Optical Network (PON). A techno-economic analysis was performed, and results show that P2P and PON approaches are very similar in terms of cost, therefore, due to technical advantages, P2P is recommended as deployment strategy for the described scenario.","PeriodicalId":205731,"journal":{"name":"2022 32nd International Telecommunication Networks and Applications Conference (ITNAC)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123184295","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 WSN is mainly composed of a set of homogeneous sensor nodes and an in-situ base-station (BS) that are randomly deployed within a delimited area of interest. These sensor nodes sense the area and transmit the sensed data to the BS through multiple wireless communication hops. In addition to data collection, the BS performs highly complex management functions and controls the entire network. The importance of the BS in a WSN makes the BS a high-value target for an adversary that wants to disable the network. To launch a denial-of-service attack on the BS, an adversary intercepts the data transmissions sent to the BS and uses evidence theory as a technique of traffic analysis to find the BS. This paper proposes a technique to counter the attack and increase the BS's anonymity by creating cells and choosing HoneyCells from the created cells; the HoneyCells mimic the BS cell and attract the adversary's attention. Simulation results show that the proposed technique provides better BS anonymity.","PeriodicalId":205731,"journal":{"name":"2022 32nd International Telecommunication Networks and Applications Conference (ITNAC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127459480","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}

Due to the limited compute and energy resources, active security protections are usually minimal in many IoT devices. This has created a critical security challenge that has attracted researchers' attention in the field of network security. Despite a large number of proposed Network Intrusion Detection Systems (NIDSs), there is limited research into practical IoT implementations, and to the best of our knowledge, no edge-based NIDS has been demonstrated to operate on common low-power chipsets found in the majority of IoT devices, such as the ESP8266. This research aims to address this gap by pushing the boundaries on low-power Machine Learning (ML) based NIDSs. We propose and develop an efficient and low-power ML-based NIDS, and demonstrate its applicability for IoT edge applications by running it on a typical smart light bulb. We also evaluate our system against other proposed edge-based NIDSs and show that our model has a higher detection performance, and is significantly faster and smaller, and therefore more applicable to a wider range of IoT edge devices.","PeriodicalId":205731,"journal":{"name":"2022 32nd International Telecommunication Networks and Applications Conference (ITNAC)","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122561376","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}
