摘要:
针对提高WSN网络寿命的优化设计问题,在网络构建上设计一个新的结构,称为无线式总线结构,此结构旨在缩短传输路径和屏蔽不必要的信息交换,从而节约能量.基于建立的总线圆和传输总线,把信息保存在总线圆上,当需要时再传递到汇聚点.需要传递的信息从传输总线上传递到汇聚点.这样减轻靠近汇聚点的传输点的压力,减少瓶颈点,延长网络寿命.同时在网络重构时,根据混杂信息量方程,提出按信息量的变化率进行重构的策略和方法,保证网络的整体能量平衡消耗.仿真实验给出方法在不同覆盖率的要求下系统的能量消耗和寿命的关系,较之于一些传统网络结构更有效.结果表明无线式总线的构建策略有利于网络调度和延长网络寿命.
Abstract:
The performance of WSN is optimized in different layers for prolonging its lifetime.A new network architecture named wireless bus is given to shorten the transition length,and screen unnecessary information interchange for saving energy.Circle bus and transition bus are proposed for reducing the burden of bottleneck which is close to the sink node,and average energy saving is obtained.The information is saved on the bus circle and is transferred when used.The nearest node reconstruction method is used for reconstructing and balancing the whole cost of energy,which is based on the mixed function of information.The reconstruction occurs when the change rate is up to the limit.In simulation test,the relation of energy cost and lifetime are given in different rate of coverage,and good performance is obtained from wireless bus architecture for network scheduling and lifetime extending.
