It stands as one of the most popular technologies for the following years and it is requiring substantial changes in the Internet protocols to meet its requirements. As the application layer is decisive for the quality of the connection, this paper analyzes the performance offered by one of the most popular protocols for the application layer in IoT: the Constrained Application Protocol (CoAP). This analysis aims to examine the features and capabilities of this protocol and to determine its feasibility to operate under constrained devices using security support. For this, a realistic network scenario is deployed to run the simulations and to measure bandwidth, consumption of resources (i.e., CPU cycles and bandwidth usage) and communication latency. Additionally, the trade-off between security and performance is discussed measuring the bandwidth overhead and the consumption increase associated to secure the communications. Different ciphering and authentication algorithms are tested, following the recommendations made by the Internet Engineering Task Force (IETF).","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1145/3416011.3424754","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72464222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nodes of the WASN are Raspberry Pi devices that not only record the ambient sound, but they also process and recognize a sound event by means of a deep convolutional neural network (CNN). To our knowledge, this is the first WASN running a CNN classifier over low-cost devices. Moreover, the network has been designed according to the open standard FIWARE, so the whole system can be replicated without the need of proprietary software or specific hardware. Although our low-cost WASN achieves similar accuracy compared to other WASNs that perform the classification through cloud or edge computing, our problem is the high computation load required by deep learning algorithms, even in testing mode. Moreover, the WASNs are designed to be constantly monitoring the ambient, which in our case means constantly classifying the \"background sound''. We propose here to introduce a pre-detection stage prior to the CNN classification in order to save power consumption. In our case, the WASN is placed in a big avenue where the \"background sound'' event is the usual traffic noise, and we want to detect other sound events as horns, sirens or very loud sounds. We have designed a pre-detection stage that activates the classifier only when an event different from traffic is likely occurring. For this purpose, two parameters based on the sound pressure level are computed and compared with two corresponding thresholds. Experimental results have been carried out with the proposed WASN in the city of Valencia, achieving a six-times reduction of the Raspberry Pi CPU's usage due to the pre-detection stage.","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75107699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increase of data rates that is mostly caused by multimedia traffic relying on QoS requirements complicates almost lossless delivery. Especially MANETs communications face these challenges, as nodes are moving at runtime. It is well known, that these network architectures have difficulties delivering time-critical data, since no central instance is in place. Bandwidth-demanding multimedia traffic easily causes stressed and overloaded network segments which result in bottlenecks and dropped packets. Introducing a SDN controller is a logical consequence to distribute traffic on nodes based on the knowledge of the entire topology. QoS requirements of all flows can be considered by the controller during routing. However, this brings up the question of how to keep the controller's topology up to date regarding lost and newly arisen connections since nodes are moving continuously. An outdated view of the topology results in deployed routes where no continuous connection between the nodes remains active. We therefore introduce CeTUP, a controller-equipped topology update process designed to provide an overview of the network as accurate as possible, before routing takes place by the controller. We show that this update process achieves QoS conform delivery rates even when nodes are moving at a speed of up to 60~km/h.","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73434561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
