A simple anti-coupled line circuit configuration is proposed to design wideband bandpass filter with sharp skirt selectivity in this paper. Good skirt selectivity can be achieved with two transmission zeros near the passband. The location of transmission zeros and bandwidth of passband can be adjusted...

In the study of the future network architecture NDN, security and privacy problem has always been a very important research topic. Aiming at this problem, this paper analyzes and discusses the security and privacy issues in NDN network security, content security and privacy, signature and credit management,...

Energy optimization of WSN is very important to prolong the lifetime of tiny and energy insufficient sensor nodes. Traditional LEACH-like energy saving approaches try to balance the load of every node, which prove to be very effective. Since, these approaches suppose that the sensor nodes are disposable;...

Wireless Sensor Networks (WSNs) with numerous spatially distributed sensors can accurately monitor a remote environment, such as humidity, pressure, distance, etc. and cooperatively send the data, combing from the individual nodes, to base station (BS). Energy saving is a great challenge for WSNs which...

Mine roof collapse is always the top issue of mine security, and apparently traditional detection methods don't have a very good performance. In this thesis, the authors present the detection performance of BOTDR technology to mine roof. The authors bring up corresponding wiring technology and methods...

Urban public transport networks are special types of Delay Tolerant Networks (DTNs) which consist of buses and other forms of transport. It is hard to establish an end-to-end link and maintain a stable network topology in this kind of networks. However, unlike other DTNs, the bus’s mobility in public...

Dividing the networks into several unequal sizes of clusters and the nodes with similar readings and neighboring geographical location are in the same cluster is an effective way to prolong the WSN lifetime. Most applications in WSNs can tolerate certain accuracy loss of the sensor readings and we can...

Key management is one of the most challenging security issues in wireless sensor networks where sensor nodes are randomly deployed in a hostile field. Considering the limitations of power, computation and communication capabilities in wireless sensor networks, key predistribution is found to be a better...

We integrated the reality and the development of the navigation technology at home and abroad, considered the operating feature of underwater wheeled mining vehicles for mines and their poor working conditions, applied the laser gyro inertial autonomous navigation system advanced at home and abroad during...

In recent years, using directional antennas to reduce the amount of interference and collisions in mobile ad hoc networks has become more and more popular. Due to the problem of broadcast storm caused by flooding route requests, a novel route request flooding approach called Hexagonal Flooding Strategy...

Command and control (abbreviated C2) is the key of integrated cooperative engagement, and directly decides the process and outcome of war. As the background of integrated engagement, in view of the analysis of several typical C2 models, based on synergetic theory and method, the definition of cooperative...

Modern communication commonly uses the complex modulation signal in order to achieve Anti-interference. Most current signal parameter estimation uses the hypothesis of some of the priori information known, which has some special features. This paper describes the design of a low SNR parameter estimation...

The Multiple–antenna technique called MIMO (Multiple-Input-Multiple-Output) constitutes a key technology for modern and future wireless communications, which trade–off superior error performance and higher data rates for increased system complexity and cost. As an extension to the classical MIMO schemes,...

Stereo vision is a strong-crossed subject, and it has been one of the most hot topics in the study of computer. In more than 40 years of development, it has formed its own method and theory. This paper systematically reviews the present situation of stereo vision research, briefly introduces stereo vision...

Urban rail Transit system is a dynamic, uncertain and complex system, it will seriously affect the traffic capacity of road network, and the convenience of people's travel in the event of emergencies. So the timely and accurate release of information is an important guarantee of the safe and efficient...

This paper proposes a Markov decision ant colony routing selection algorithm based on the multi-parameter equilibrium. In this routing algorithm, five unit group Markov routing decision model based on IoT is build, network link quality, node residual energy and neighbor node number three aspects is considered,...

This paper addresses the maneuvering target tracking with a single ESM sensor where only the bearing and elevation measurements are available and used for the target trajectory estimation. In single ESM tracking system the maneuvers of observer platform are required for the observability. The maneuver...
