能量收集通信系统中数据传输的研究

Research on Data Transmission for Energy-Harvesting Communication Systems

研究在具有能量收集功能的传输节点中数据传输的问题.一方面,对于给定随机到达的数据和能量,研究了通过自适应改变传输速率使得总传输时间最小的优化问题和实现算法.另一方面,研究了初始能量和数据量对最小传输时间的影响.通过仿真验证了传输策略的最优性以及影响最小传输时延的因素.

The data transmission problem is investigated in the transmission nodes that can harvest energy from nature. On the one hand, transmission rate is changed adaptively according to the traffic load and available energy,such that the time by which all packets are delivered is minimized. On the other hand,the influencing factors of transmission time minization are studied. To the end, the optimality of the transmission strategy and the factors that affect the transmission delay minimization are verified.
