This paper investigates a dynamic bandwidth allocation strategy with secrecy constraints, where big data can be viewed as a resource instead of a burden from the traditional perspective. Unlike usual cases, we take into account big data and security issues along with bandwidth allocation. It is reasonable to assume that big data derived from mobile network, by a series of processing, can generate...
Network-off communications is a kind of trunking communications technology, when BS is destroyed, the mobile terminals (MT) can still maintain connectivity for implementing data transmission. This paper proposes the network-off model, and describes the network-off features. By analyzing the node successful transmission probability, the influences of transmission distance and power to network-off are...
In this paper, we present a comprehensive survey on complementary code (CC)-based multiple-input multiple-output (MIMO) code-division multiple access (CDMA) for futuristic wireless communications. This paper starts with the construction of CCs and then proceeds to describe the design of CC-based CDMA and MIMO wireless communication systems. Complementary-coded chip-level space–time coding offers a...
Mobile anchor node is used for localization in Wireless Sensor Networks. It can lower the cost of network and reduce the dependence of localization precision of the algorithm on the density of anchor nodes. However, in the existing algorithm for the localization of mobile anchor node, little research in detail has been done on the path of mobile anchor node and the timing of sending beacon. In this...
The purpose of this paper is to discuss the maximum service range of reference receiver in Assisted Global Navigation Satellite System(AGNSS) mobile positioning. In the research, the scenario which including spatial constellation of Global Navigation Satellite System(GNSS) and the ground facilities is established by Satellite Tool Kit(STK) and a general application environment is simulated. By modeling...
According to the security features of WiMAX-based wireless communication network, a fresh new wireless communication authentication protocol called WCAP was advanced and designed adopting the dual-key authentication scheme based on trusted third party; its security was analyzed by two means of technical realization and formal analysis; the protocol was implemented by devising an integrated security...
