For V2V performance through 5.86GHz WAVE band. Measurements were performed in Choenan-si of South Korea. We found out that the fading reduction effect of the selection diversity antenna compared to the 2×2 smart antenna was 0.65–4.25dB higher in LOS and 1.15–1.75dB better in NLOS channel environments. This is because the beam width of the our 2×2 smart antenna system is very wide. With this, it is expected that the fading reduction effect can be obtained by narrowing the beam width appropriately and also arranging the spacing between the elements of the smart antenna.","PeriodicalId":284480,"journal":{"name":"2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114662196","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}

WPS is used to identify entities inside the human habitation area using radio waves collected by smart devices. The proposed system focuses to track an individual in a bounded environment. The recognition of the entity can be achieved by Radio Frequency Identification (RFID) transponders. The RFID trackers accomplish fingerprinting with the Unique Device Identification (UDI). The procedure is deployed using an RFID sensor based application which pinpoints the location of the personnel inside architectural frameworks. The position co-ordinates in the indoor area can be using the WiFi technology. The mechanism is split into two sections — Data Collection and Position Identification. The data collection combines the location information acquired from the sensor technologies. The identification of an individual with RFID transponders which results in the tracking of the entity. The location information obtained from the sensors are without time constraints and is updated in the RFID readers and databases including the last time zone. Design and development of the application from connecting to the sensor devices, distance estimation between the sensor devices and the entities, retrieval of the exact position information are deliberated. The pseudo code to connect to the nearest sensor device and obtain the location information is stated.

The paper analyzes the relationships among the transmission range, carrier-sensing range, and interference range in case that channel bonding mechanism is adopted and proposes a MAC protocol for IEEE 802.11ac WLANs to avoid collisions.

Although the content is secured with different encryption techniques, open wireless channel allows an adversary to analyze traffic patterns, trace back and locate the source node. To achieve source-location privacy, several techniques based on flooding, random walk and dummy traffic transmission are proposed for WSN. In this paper, we propose a new routing method that randomly forwards a packet towards the sink such that an adversary will find difficult in tracing the source location. We evaluate privacy of our proposed method in terms of success rate of an adversary. The simulation results show proposed routing strategy is better in preserving privacy.","PeriodicalId":284480,"journal":{"name":"2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125192106","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}

Although, various analytical models have been exhibited for different protocols in VANETs, but a detailed model for VANETs is not available in literature.

To reach all users readily, video streaming on HTTP gets popular as HTTP is supported almost in any existing platforms. Dynamic Adaptive Streaming over HTTP (DASH) represents a great standard for multimedia services in Internet. In order to offer better user experience and cope with dynamically varying network conditions, a big challenge is to estimate precisely next segment bandwidth, which is a significant premise in determining next multimedia bitrate. This paper investigates the effectiveness of exiting bandwidth estimation schemes and our presented MACD based Bandwidth Estimation Scheme (MBES) in wireless environment. The simulation results show that when the network bottleneck is on the backbone network, MBES can perform well and is superior to other existing scheme although not as well as that in the wired network.","PeriodicalId":284480,"journal":{"name":"2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124608560","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}

To reduce collision probability, each node selects its group, which is predetermined by a distance from the fusion center based on RSSI level, and aligns its transmission time to the farthest node in the group. To reduce collision in a node group, nodes choose their subcarriers to load their information based on the RSSI level. Computer simulations demonstrate that Reception Success Rate (RSR) of the proposed scheme has five times larger than that of conventional PN sequence random access. Maximum throughput of the proposed method also exhibits two times larger than the conventional PN codes.","PeriodicalId":284480,"journal":{"name":"2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128719099","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}

Every ship that comes in and out the harbor should be monitored real time. Monitoring of every ship can be conducted by gathering information of the ship, such as speed and location. However, the speed and location of illegal ships are difficult to be gathered because they usually turn the Automatic Identification System (AIS) signal off. In this paper, we develop ship location detection using Wireless Sensor Networks (WSN). We use four cooperative sensor nodes to detect ship-generated wave. Assuming that each sensor is equipped with Global Positioning System (GPS), we derive a new formulation to compute location of the illegal ships. The new formula is able to locate the ship in three different directions. We also quantify the necessary conditions of ship location detection.","PeriodicalId":284480,"journal":{"name":"2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126989279","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}
