In the process of network transmission, we usually need to store and forward data at the location of intermediate nodes. Because of information security, we can’t code in a reasonable way. Therefore, we put forward t...

When the UAV technology meets the multiple-input-multiple-output communications, the precoders for transmission need to fertilize the benefits of high-probability lineof-sight propagation paths. This work investigates the joint design of uplink/downlink precoders for single-cell UAV-mounted wireless systems. While the UAV has finite cruising endurance, the UAV-mounted base transceiver station can scavenge energy from wireless signals in the uplink period, and the deliver useful information to terrestrial users in the downlink period. By exploit the information-theoretical uplink-downlink duality, the weighted throughput can be maximized based on the tailored dirty paper coding scheme. Numerical results are used to demonstrated the effectiveness of the proposed algorithm.

based on the research on the existing grid and parallel computing technologies, this paper proposes a grid-based parallel computing platform design scheme, and implements the key modules in it. The test results show that the platform acceleration effect is very significant, and this platform is simple, fast and easy to implement.

Power management is the key issue in the design and operation of wireless network applications like sensor networks, pervasive computing and ubiquitous computing where the network is primarily driven by battery-powered embedded devices. This paper studies network coding as power minimization technique. Network coding is a new research area that may have interesting applications in practical networking systems. With network coding, intermediate nodes may send out packets that are linear combinations of previously received information. Thus network coding reduces the power consumption by minimizing the number of transmissions required to communicate a given amount of information across the network. Hence it improves the lifetime of the network when network coding is being applied. This paper explains what is network coding and the benefits of network coding. Evaluation results indicate that the proposed solution is more efficient than no-network coding solution while still meeting the required lifetime constraints.
The key to the efficient operation of turbo codes is the interleaver design. With proper design, the pairing of low-weight sequences to the input of the encoders can be avoided. Circular shift interleavers can be used...

We introduce a framework to extract and parse Java source code, serialize it into RDF triples by applying an appropriate ontology and then analyze the resulting structured code information by using standard SPARQL queries. We present our experiments on a sample of 134 Java repositories collected from Github, obtaining 17 Million triples about methods, input and output types, comments, and other source code information. Experiments also address the scalability of the framework. We finally provide examples of the level of expressivity that can be achieved with SPARQL by using our proposed ontology and semantic technologies.
