Cyber-physical systems (CPS) have the great potential to transform people’s lives. Smart cities, smart homes, robot assisted living, and intelligent transportation systems are examples of popular CPS systems and applications. It is an essential but challenging requirement to offer secure and trustworthy real-time feedback to CPS users using spectrum sharing wireless networks. This requirement can...
Data veracity ensures that the data used are trusted, authentic and protected from unauthorized access and modification. In order to implement the veracity of big data, specific trust models and approaches must be designed and developed. In this paper, a category based context aware and recommendation incentive based reputation mechanism (CCRM) is proposed to defend against the internal attacks to...
Large scale multiple-input multiple-output (MIMO) system is considered one of promising technologies for realizing next-generation wireless communication system (5G) to increasing the degrees of freedom in space and enhancing the link reliability while considerably reducing the transmit power. However, large scale MIMO system design also poses a big challenge to traditional one-dimensional channel...
The mobile social network (MSN) can be considered as a system which provides a variety of data delivery services involving the social relationship among mobile users. Mobile social networks have the surprising property of being "searchable": Ordinary users contact with each other more frequently when they have more social features in common. In this paper, we first define a priority relationship...
In this paper, we present a novel Cluster-based Separate Networking Coding (CSNC) scheme, as a solution to solve the problem of continuous data collection for WSNs with a mobile BS. By separately encoding a certain number of data segments in a combined data segment and doing decoding-free data replacement, CSNC not only provides efficient storage method for continuous data, but also maintains a high...
In WCDMA system, rate assignment algorithm on the downlink for the data transmission is proposed. The optimization goal of the resource allocation strategy is choosing appropriate utility function. The utility function reflects a flexible tradeoff between total system throughput and fairness. The power is distributed through the control module and the scheduling module. The simulations show the performance...
This paper analyzed the basic model for the e-payment industry with the agent under the guidance of Two-sided Market, and introduced the 2-stage game of adoption strategies for both the Platform and the Buyer. Then the authors made a deep through case study for three dimensions: speed improving, convenience improving and safety improving, mainly based on the functions of the agents in e-payment application...
There are some papers on secure or anonymous routing protocol in mobile ad-hoc networks. However, due to their original design goal, most of them are vulnerable to attacks and inefficient. In fact, providing security and anonymity are critical in wireless ad hoc networks. In this paper, we present an efficient secure anonymous routing protocol for clustered mobile ad-hoc networks, which not only solves...
This paper introduces a design for mobile node of sensor networks using robot. The robot is composed of micro processor module based on AT91RM9200, Bluetooth module, wireless network card (SISCO AIR-PCM350), GPS module, mobile base and motionless Bluetooth sensor node distributing module. Embedded arm-linux OS installed on micro processor module based on AT91RM9200 makes it have the ability of processing...
Topology control is an effective measure at network layer to implement power control for energy-saving, which is a critical issue in ad-hoc wireless networks. Topology control also affects other significant performances of network, such as packet delivery radio, end-to-end delay, and network capacity etc. Various techniques and algorithms have been proposed to achieve the optimal topology which can...
