中文摘要： 煤矿物联网井下的无线通信受到恶劣环境影响、资源受限等约束导致网络传输的可靠性较低，现有的无线传感器网络可靠性传输机制往往从启发式设计开始，网络机制与优化理论的偏离使得后续演进的实施代价增高，也为服务质量的保障设下了难题。本课题针对煤矿物联网的自身特性，主要研究三个内容：(1）无线传感器网络传输任务可靠性的评估模型和动态评估框架；(2）在能量及时延约束条件下对传输任务进行可靠性优化，利用改进的进化算法求解可靠性-冗余分配问题；(3）以优化的冗余数量作为自适应调整的参数，采用网络编码和协作传输技术研究基于多源多中继网络模型的煤矿物联网可靠传输机制。本项目将优化理论与传输机制结合，使得煤矿物联网中感知信息的可靠传输机制从设计、评估到管理都有充分的理论依据。

英文摘要： Reliability of transmission in coal mine Internet of Tings is lower because it affected by resource-constrained and harsh environmental factors. Most of the existing reliable transmission systems for wireless sensor networks are heuristic algorithm. The separation between network mechanism and optimization theory makes the cost of subsequent evolution implementation increases and also sets a problem for the protection of the quality of service. Considering the characteristics of the coal mine IoT, three contents will be researched such as: (1) Build a reliable data transmission assessment model and a dynamic assessment framework for wireless sensor networks. (2) Optimize transmission reliability under the constraints of energy and delay, utilize the improved optimization algorithm to address the reliability-redundancy allocation problems. (3) Put the redundancy of optimizing as the parameters of the adaptive adjustment, utilize the technologies of network coding and collaborative transmission to research the reliable transport mechanism for wireless sensor networks based on multi-source and multi-relay model of networks. The project will combine optimization theory and transport mechanism, making reliable transmission mechanism of perceptive informatics in Coal Mine IoT has sufficient theoretical basis from design to evaluation and management.
