With the proliferation of smart mobile devices (smart phone, tablet, and wearable), mobile crowdsensing becomes a powerful sensing and computation paradigm. It has been put into application in many fields, such as spectrum sensing, environmental monitoring, healthcare, and so on. Driven by promising incentives, the power of the crowd grants crowdsensing an advantage in mobilizing users who perform...
The proliferation of crowdsourcing brings both opportunities and challenges in various fields, such as environmental monitoring, healthcare, and so on. Often, the collaborative efforts from a large crowd of users are needed in order to complete crowdsourcing jobs. In recent years, the design of crowdsourcing incentive mechanisms has drawn much interest from the research community, where auction is...
The research on search and rescue after landslide is very important for improving the victims' survival rate. In this paper, the improved Truncated Lévy walks are used to simulate rescue teams' search behaviors. We propose a cooperative rescue plan based on distributed auction mechanism and simulate its effect in three disaster scenarios "fatal", "serious" and "normal"...
The performance of wireless networks can be significantly improved by multi-channel communications compared with single-channel communications since the use of multiple channels can reduce interference influence. In this paper, we study interference-aware topology control in IEEE 802.11-based multichannel wireless mesh networks with dynamic traffic. Channel assignment is one of the most basic and...
As to H.264/AVC watermarking technique, it is a key issue to select some proper image blocks for watermark embedding, that can reduce the increase of watermarked-stream bitrate, strengthen the robustness of watermark and improve the quality of the watermarked video. A new H.264/AVC watermarking algorithm based on the sort of prediction-residual energy is proposed in this paper. Through comprehensively...
