Examples of sensor networking applications include fire detection, disaster recovery, crowd management and many others. The two parameters; signal delay and energy consumption are very interconnected with a huge tradeoff as trying to control one of them will certainly affect the other adversely. The objective of this paper is to propose a scheme of network architecture where both parameters are optimized resulting in minimum energy consumption and minimum possible signal delay. We propose implementing partial aggregation as opposed to no aggregation or full aggregation. Results obtained from the test carried on an actual network setting have shown that partial aggregation works better compared to the other two techniques.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127514009","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 these vehicles, driving control decision is obtained based on the collection of massive traffic states and intensive information processing. However, the spatial-temporal characteristics of the traffic states and the constrained environmental perception range of an individual vehicle seriously undermine the effectiveness of the state collection. Multi-agent empowered collaborative decision provides a potential approach to address the problem. This paper proposes a multi-dimensional information fusion mechanism, which improves the utilities of vehicular information processing and autonomous driving. Moreover, we design an intelligent distributed decision algorithm for autonomous driving applications, which optimizes road traffic flow under vehicular resource constraints. Numerical results demonstrated that our proposed scheme significantly increases the system revenue.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124875881","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}

From the wave functions, the Love equivalence principles are used to generate the emission from the uniform and cavity modes (wave functions). For most of the annular wave functions, the infinite degeneracy of the modes with line nodes through the geometric center most likely will result in no cavity mode enhancement of the output power. Forming the slit breaks that infinite degeneracy into a double degeneracy of modes that are odd or even about the slit. Pictures of the wave functions and the uniform and cavity mode contributions to the output power distribution will be shown. The consequences for forming arrays of such devices will be discussed.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130533719","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 triaxial electric fields at the 8 corners of the defined working volume are measured using electric field probes for the complete rotation of mechanical stirrer. The data is obtained for the frequency range of 80 MHz -1000 MHz with 85 frequency samples as per standard requirements through the designed data acquisition software. The stirrer step size was $7.2 {o}$ which results in 50 steps of the stirrer for one complete rotation.

In this article, a method based on parametric imaging of the polarization status of reflected or transmitted light from biological tissues in the NIR spectrum was proposed. By modulating the polarization states of the NIR illumination source, recording the images of the samples, the far-field variation of the pixel intensity of recorded images was fitted to a theoretical model, and a series of polarization parametric images were obtained. These images describe the relation between the polarization status of the reflected or transmitted light and the properties of the samples. A tissue phantom with deep buried test target was imaged successfully. This method can provide a useful detection method for the deep imaging of biomedical tissues.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132289317","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}

One of the research areas that needs attention is the detection and mitigation mechanism of Content Poisoning Attack. This attack isolates the legit contents from the network and propagates the fake or malicious content to the consumer. In this work, we use Name-Key Based Forwarding and Multipath Forwarding Based Inband Probe to mitigate the attack with the ‘novel’ additional security feature.

Since AUVs are battery-powered and therefore energy-constrained, their energy consumption is a critical consideration in designing underwater wireless sensor networks. The energy consumed by an AUV depends on the hydrodynamic design, speed, on-board payload and its trajectory. In this paper, we optimise the trajectory taken by the AUV deployed from a floating ship to collect data from every cluster head in an underwater sensor network and return to the ship to offload the data. The trajectory optimisation algorithm models the trajectory selection as a stochastic shortest path problem and uses reinforcement learning to select the minimum cost path, taking into account that banked turns consume more energy than straight movement. We also investigate the impact of AUV speed on its energy consumption. The results show that our algorithm improves AUV energy consumption by up to 50% compared with the Nearest Neighbour algorithm for sparse deployments.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131779049","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}
