Sari","doi":"10.1109/WPMC.2017.8301834","DOIUrl":"https://doi.org/10.1109/WPMC.2017.8301834","url":null,"abstract":"Wireless sensor networks is a rapidly emerging technology implemented in various applications for several domains. One of the important considerations in wireless sensor networks is the network lifetime because the sensor nodes are battery powered and difficult to replace or recharge when they are deployed in dangerous or inaccessible environments. Various node clustering approaches have been implemented to achieve energy efficiency in order to prolong the network lifetime. However, the approaches are only suitable for a certain application scope. The data similarity aware node clustering is a specific application that does not consider load balancing of clusters, so that it also requires a proper routing protocol. The main challenge in such clustering approach is that some nodes are far apart from other nodes and the network structure change dynamically. Therefore, it is required a dynamic multi hop routing protocol to address the problem. In this work, we propose a dynamic multi-hop routing protocol based on the rules incorporating fuzzy system and particle swarm optimization to obtain the priority factor of cluster head election. Our proposed Dynamic Multi-Hop Routing for Unbalanced Sized Cluster (DMHR-USC) protocol was compared against the K-hop Clustering Algorithm (KHOPCA) protocol to justify the performance. The DMHR-USC can reach the network lifetime longer than the KHOPCA in all terms of the First Node Dies (FND), Half of Nodes have Dead (HND), and the Last Node Dies (LNd). Therefore, the DMHR-USC can prolong the network lifetime in a relative significant manner.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127755215","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}

First, a hierarchical interest model is introduced to organize the semantic category of locations in human mobility logs as well as representing their personalized mobility patterns. Then, by combining the interest models of different people, a 3-modes tensor with the features of person identity, time, and the semantic category of location is constructed. Tensor factorization is utilized to reveal people's mobility interest on different kinds of locations. Finally, personalized interest models are recovered from cumulative tensor to predict human mobility in a person-by-person way. Extensive evaluation results based on a large scale check-in dataset from real location-based social networks have validated that our proposal achieves better recall, precision, and F-Score in human mobility prediction as compared with the state-of-art approach.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128653906","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}

Finally, hints are given on how a given level of performance can be maintained as the number of beacons is further decreased. To answer those two questions, almost 30 433MHz/868MHZ-UHF-RFID active tags have been deployed both in a corridor and in a hall environment.

If the nodes trustworthiness is unknown or the detected events truthfulness is also unknown, the event detection is a difficult task. In our paper, we study this challenge and observe that applying expectation maximization with genetic algorithm, trustworthy event detection is possible. We find the best local maximum points using Expectation Maximization and then gradually applying Genetic Algorithm we find the best value. We find our hybrid approach performs better since the best selection with the maximized expectation goes for evolving the new generation. In the long run, new generation becomes better and contributes faster. We do simulation study to support our model. We provide a comparative study among Genetic Algorithm and Expectation Maximization and the hybrid of the two above mentioned methods. We find that our proposed hybrid model provides better framework to find the trustworthy nodes, better convergence rate, more authenticated event detection.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128113254","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}

However wireless sensor networks are vulnerable to many attacks such as denial of service. Therefore, the number of security threats has increased dramatically due to the increase in the number of applications adopted wireless sensor networks. Physical layer security is considered to be more robust than upper layers security. In this paper we address the problem of evaluating popular techniques (Reed Solomon techniques and scrambled error correcting) in term of security gap which is the difference between the signal to noise ratio of the legitimate receiver and the signal to noise ratio of the eavesdropper. Our work compare scrambled t-error correcting codes with Reed Solomon using bit error rate and security gap. Experiments and analysis showed that Reed Solomon has almost the same security gap as scrambled error correcting codes which requires more computational power than Reed Solomon.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127511056","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}

Frequency sharing among such devices is an important study issue. For their smooth introduction, it is essential to develop a signal detection technology with low complexity and high sensitivity. We have studied a signal detection scheme using a cyclic prefix usually attached to an OFDM signal. However, the probability distribution of the detection performance, which gives false-alarm and non-detection probabilities in signal detection, has been considered only by Monte Carlo simulation. This paper presents the formulation of the detection performance, and its verification by hardware implementation. Experiments using the detector operating in the radio frequency band verified that the false-alarm and nondetection probabilities calculated by the analytical formula agree with those by the hardware experiments.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123267508","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 this evaluation, a wireless system with OFDM signals is assumed and an LED linearization method which uses clipping followed by inband filtering and pre-distortion is employed.

In this work we propose a system architecture to deliver UHD content adaptively based upon bandwidth and end user device specifications over wireless network. For the adaptive transmission we need a Parametric rate model for bit rate adaptation. Hence, we study the effect of quantization, frame rate, and spatial resolution on bit rate in order to develop a Parametric rate model for SHVC videos. The rate model is developed in terms of quantization step size, frame rate, and spatial resolution. It is observed that the model fits into measured data with high Pearson Correlation. The rate model helps in deciding the quantization parameter, frame rate, and spatial resolution for the given bandwidth conditions so as to improve the user experience. The receiver sends the channel conditions and device capabilities (like device resolution support and processing power) to the transmitter. Based on this, the transmitter adaptively changes the transmitted bit stream. The overall system performance is evaluated in terms of the PSNR of the transmitted and received video sequence.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132710101","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}
