A video data sampling and transmission system is designed for video monitoring based on wireless mesh network. Discussion is made on the use of standards, working frequency, network infrastructure, coverage solutions, link budget, frequency planning, power supply, supporting transmission and AC design....

Abstract.Underwater localization are an importantpart of underwater sensor networks (USNs). USNs attracted significant attention, they are widely used for many applications, such as tsunami before the reaching inhabited areas, pollution monitoring, civilian and military applicationsOcean resource exploration,...

The switching equipment on traditional networks have limited capabilities and the exchange of the switching equipment is often associated with long time frame and high development cost. SDN deployment controller under the flow table rules also exists to handle message delay. In this paper, we propose...

Abstract: To solve the prediction problem of hybrid data in users' consumption information of telecommunication, the paper use the fuzzy K-Prototypes (FKP) and support vector machine (SVM) combined model to improve the accuracy of users churn prediction. In the combined model, FKP is adopted to cluster...

Wildfires can cause transmission lines to trip, which can prove difficult to reclose successfully. Using satellite remote sensing technology to monitor wildfires can alert the power sector to potential damage. However, wildfires along transmission lines may have a small burned area and may spread rapidly....

Based on the related generalization of Vague set algorithm of intuitionistic fuzzy theory, this paper applies it to UWB marine ship precision positioning technology, puts forward new research methods and calculation formulas, and constructs the similarity measure between them and obtains new formula...

Abstract.To address the inaccuracy of multi-storey indoor positioning, the paper proposes a method involving WiFi fingerprint positioning based on the prior information of map environment and position correction based on the image recognition technique. First, we establish a model of map environment...

Abstract: This paper considers channel estimation for mmWave communication with massive received array antennas at BS. Instead of estimate the channel matrix, we resolve the problem into two steps. Firstly, one could separately estimate DOA, on the basis of the array signal processing techniques, and...

Pedestrian detection and retrieval plays an important role in intelligent video surveillance and automobile auxiliary driving system. Video surveillance creates mass monitored data among which a little effective information exists and could be hardly found. To settle the problem, based on pedestrian...

Software definition network (SDN) as a new model of the future network architecture system, which gains the academic and industry attention. Large traffic often leads to congestion and transmission of network links. Equal-Cost Multi-Path (ECMP) routing can play a significant role in balancing the load,...

The Ultra-Wideband antenna can effectively improve the system performance, such as range resolution, anti-jamming performance and complex target recognition. It is very important to study the UWB antenna. In this paper, the UWB antenna is discussed and studied, and the influence of antenna size miniaturization...
