摘要
以规模相等单跳分簇无线传感器网络为背景,针对传感器节点在数据传输过程中的推和拉两种模式,分别提出了簇内普通节点和簇首节点在数据传输过程中的能耗计算公式,并计算出两种数据传输模式下簇内节点的能耗。利用实验验证了所提出的能耗计算公式的有效性,方便用户根据不同需求选择传感器节点传输机制,最大限度地延长无线传感器网络的生命周期。
In the background of equal-sized single-hop clustlered wireless sensor network （WSN）, according to the data transmitting modes-pull mode and push mode, the energy consumption formulas of ordinary nodes and the cluster head （CH） within a cluster are put forward during the process of data transmission. The energy consumption of sensor nodes within a cluster is calculated in the two modes. Experimental results verify the validity of the proposed energy consumption calculation formulas. It is convenient for users to choose data transmission mechanism of sensor nodes according to different demands, and it extends the life cycle of WSN as long as possible.
