为减少无线传感器反应网络(WSANs)中传感节点和反应节点间数据包的传输距离及传输能耗,在分析了传感节点与多个反应节点共存模型的基础上,提出了一种分布式的跳数有限且能耗自适应的多反应节点选择算法,并给出了相应的最优解决方案的整数线性规划(ILP)描述.该算法在修改了贪婪转发路由算法的基础上,通过限定传感节点到反应节点的跳数以及重新计算从每个用于数据转发的传感节点到每个反应节点的能耗,来达到保证实时收集数据条件下降低网络总能耗及数据传输总距离的目的.仿真实验表明,该算法能够有效地实现数据收集的实时性与网络总能耗之间的平衡.图3,参8.
In order to reduce the transmission distance and energy consumption of data packets between sensor nodes and reaction nodes in wireless sensor networks (WSANs), a coexistence model of sensor nodes and multiple reaction nodes is analyzed. A distributed The algorithm of multi-reactive node selection with limited hop count and energy consumption adaptive is proposed and an integer linear programming (ILP) description of the corresponding optimal solution is given.On the basis of modifying the greedy forwarding routing algorithm, The number of hops from sensing node to reactive node, and the recalculation of energy consumption from each sensor node used for data forwarding to each reactive node to ensure that the total network energy consumption and total data transmission distance are reduced under the condition of real-time data collection The simulation results show that this algorithm can effectively achieve the balance between real-time data collection and total network energy consumption.
