With the tremendous volume explosion of big data video contents in future wireless networks, ensuring Quality of Experience (QoE) of the End User (EU) by leveraging communication context becomes an important issue. In this paper, we propose a context-aware wireless multimedia relay solution to incentivize user devices participating in wireless relay services. In this proposed approach, QoE and price...
We present optimization algorithm for relay (RLY) selection and, source (SRC) and RLY power allocations in a cooperative multicast millimeter-wave (mmWave) system with non-line-of-sight (non-LoS) sensing. We show that there is a significant benefit to the system outage performance by allocating powers for the SRC and the RLYs selected from the candidates availing of line-of-sight (LoS) paths. Specifically,...
We develop an optimization technique for a two way asynchronous relay network. A space-time processing based transceiver is proposed for spatial multiplexing in a two-way relay network. The optimization aims to minimize the transmission power at the relays while satisfying the signal to interference-plus-noise ratio (SINR) target for each user. The problem is solved using semidefinite programming.
Bot nicknames within one IRC-based botnet must have uniform structure, because they are generated by the same bot fixedly. In this paper, the similarity of nicknames in the same channel is defined by the term dasiachannel distancepsila. And a novel algorithm based on channel distance is proposed to detect IRC-based botnets. The most significant contribution of this algorithm is that it can detect...
