基于B样条函数无线传感器网络能量有效性研究

为了有效地利用有限的存储能量，延长网络使用寿命，提出了一种基于B样条函数解决网络节能的新方法，即在已知坐标的网络中计算出合理有效的控制点，在误差范围内，用控制节点传输的数据表征整个网络的数据，使控制结点的数量较大幅度少于网络数据总结点量，从而使得网络中采集、处理、传输所消耗的能量大大减少，明显地提高了能量利用的有效性，且此方法也可较好地与其他节能路由协议相结合。通过仿真实验验证了该方法具有明显的节能效果，节能率超过传统方法的50倍以上。

Study on wireless sensor network energy-efficiency based on B-spline

In order to make use of the limited storage energy efficiently and prolong the life-span of the net,a new arithmetic of network energy-saving based on B-spline is put forward in this paper.In a coordinated net,it can rationally work out valid control nodes and the data transferred by control nodes can denote the characteristics of the data of the whole net within its error limit.Therefore,the number of the control nodes is less than that of the total data nodes,moreover,the energy loss during the process of data acquisition,data processing and data transfer can be reduced greatly.The energy efficiency can thus be enhanced apparently,and this arithmetic can also be well combined with other energy-saving route protocols.Finally,the validity of this arithmetic is proved by the results of simulation experiment,and the energy efficiency is about 50 times that of the traditional method.
