摘要
Abstract
When the battery is over-charged , the solar-powered sensor nodes tend to generate extra energy .The energy is wasted when it is not utilized.The paper proposes a reliable data delivery method based on solar constraint (RDDMSC), which, by using the surplus energy, adaptively adjusts the redundancy of erasure codes during communication .It enhances the reliability of delivery as the network lifetime is kept untouched.First of all, the problem is described as ensuring at utmost the transmission rate of end-to-end data packages when there is energy constraints.It is proven that when link quality is not bad , the objective function is certainly concave .Hence convex optimization is used to solve the reliable delivery problem.Experimental results demonstrate that RDDMSC can effectively take advantage of surplus energy to improve data delivery rate .关键词
