The theory of lifelong education have made a significant impact on China's adult higher education, it confirms the value of the adult higher education, guides the development direction of adult higher education, and pointes out the changes of adult higher education. Adult higher education need to make positive changes on the thoughts, the teaching contents and methods under the life-long education...
To guarantee the quality of service for different delay-sensitive sessions while enhancing resource utilization in home machine-to-machine network is a challenging issue. To solve this problem, we propose a Distributed Admission Control Algorithm with Soft Resource Allocation (DACA-SRA) for hybrid medium access control in home machine-to- machine networks. The proposed DACA-SRA can enable resource...
Ad hoc networks have been paid more attention recently in underground mines. Due to its flexibility and quick deployment, ad hoc networks are widely used in emergency occasions such as mine collapses when communication infrastructure is destroyed. However, underground mines are harsh environment where corrosive water, dust and toxic and explosive gases are commonly present. And the characteristic...
This paper presents a simulation analysis method of degradation behavior for electro-hydraulic servo valve (EHSV). Unlike traditional statistical methods, our work is motivated by the failure mechanism of erosion wear. We assume that degradation trend of flow characteristic is related to structure wear in the valve components. Hence, in this paper, twin flapper-nozzle servo valve is considered as...
Supporting quality of service (QoS) while fulfilling high efficiency of bandwidth utilization is challenging in wireless mesh networks. To deal with this issue, hybrid medium access control (MAC) protocols are effective candidates because they can achieve QoS support and better resource sharing at the same time. However, in multi-hop communication environments, hybrid MAC protocols suffer from interference...
Multi-hop wireless communication is playing a key role in today's communication networks. Despite several advancements in communication protocols and technologies, QoS provisioning is still a challenging issue in multi-hop wireless communications. In this paper, we propose a novel scheduling mechanism based on resource reservation for guaranteeing the QoS performance of real-time sessions (RTSNs)...
Quality of Service (QoS) provisioning in multi-hop wireless networks (MHWNs) has become a promising and challenging topic in the wireless communication research community. In this paper, a novel distributed MAC scheduling protocol with reservation mechanism is proposed for enhancing the QoS performance of IEEE 802.11e-based MHWNs. The proposed mechanism guarantees resources in pre-configured contention-free...
Resource reservation is one of the effective solutions in guaranteeing the quality-of-service (QoS) in communication networks. In this paper, we propose a novel resource reservation scheme for dynamically managing the bandwidth resources in IEEE 802.11e-based wireless local area networks (WLANs). The proposed solution consists of two components namely (i) dynamic medium access control (MAC) scheduler...
