中文摘要： 生命特征的感测是人类面临且急需解决的重大挑战之一，无线体域网（WBAN）是实现生命感测新的重要手段，其显著特征是网络的能量有限性和高动态性，因此该网络必须具有高能效和高可靠性。然而目前未见切实有效的高动态自组网方法，缺乏有效的WBAN节能控制与可靠性理论和方法。本项目针对上述问题，提出多姿态下WBAN网络有效且快速的动态自组网与状态无缝切换方法，重点研究不同姿态下WBAN高能效函数的设计问题，建立多姿态下WBAN网络数据传输的可靠性方法和准则。 其创新性工作有：1）运用能效函数，建立单姿态和多姿态下WBAN高能效函数的设计方法及准则。2）针对不同姿态下WBAN网络结构的高动态性，提出有效且快速的动态组网与状态无缝切换方法。3）构建了多姿态下支持动态资源调度的可靠底层MAC传输协议。成果将形成我国独立知识产权的WBAN能效和可靠性算法，为WBAN的研究与应用奠定新的理论方法和工具支撑。

英文摘要： One of the most major challenges that human must face is the sensing of life characteristics. Wireless Body Area Network (WBAN) is widely considered as an important method for realizing it. Due to the energy-limited and highly dynamic nature, it is necessary for WBAN to have high energy efficiency and reliability. However, there is no effective high dynamic ad hoc network method to achieve energy-saving and reliability. Based on the above problems, an effective and fast dynamic ad hoc network and seamless switching method of WBAN for multi-postures is proposed. The high energy efficiency function of WBAN for different posture is designed. The data transmission method and the principle of WBAN for multi-postures are established. The novelty of the work is as follows: 1) The design method and the principle of WBAN high energy efficiency function for single posture and multi-postures are established by using energy efficiency function. 2) Based on its high dynamic characteristic, an effective and fast dynamic ad hoc network and seamless switching method of WBAN for different postures is proposed. 3) A reliable Medium Access Control (MAC) protocol that supports dynamic resource allocation for multi-postures is constructed. The outcomes of the project will form the algorithm of WBAN energy efficiency and reliability
