多事件节能的无线网络传感器协议

Multi-Event Energy Efficient Wireless Network Sensor Protocol

为了解决距离基站(Base station,BS)较远的传感器节点使用多跳通信向BS传输数据时产生更高能量消耗和使用寿命短的问题,该文提出了一个多事件节能蚁群优化数据传输(Energy Efficient Ant Colony Optimized Data Transmission,EEACODT)无线网络传感器协议.该协议消除了现有协议的一些限制和缺点,根据距离汇聚节点的节点距离将网络划分为多个扇区,根据扇区位置为节点分配特定的活动时间,以此来实现高效节能.该协议采用蚁群优化进行簇间通信,每个簇中簇头选择取决于它到BS的距离和剩余能量,中继节点的选择基于到BS的距离、剩余能量和队列大小这3个条件.实验表明与PSO协议和FAMACROW协议相比,本文EACODT协议在能耗、延时和包传输率方面均优于现有方法和性能.

In order to solve the problem of higher energy utilization and shorter service life when the sensor nodes farther from the base station(BS) use multi-hop communication to transmit data to the BS, a multi-event energy efficient ant colony optimized data transmission wireless network sensor protocol has been proposed in this paper. The protocol eliminates some of the limitations and disadvantages of existing protocols. It divides the network into multiple sectors based on the distance from the node of the sink node, and allocates specific activity time to the node based on the sector location. In this way, energy efficiency is achieved. The protocol uses ant colony optimization for inter-cluster communication. The selection of cluster heads in each cluster depends on its distance from the BS and the remaining energy. The selection of relay nodes is based on three conditions: distance to the BS, residual energy, and queue size. Experiments show that compared with the PSO protocol and the FAMACROW protocol, the EEACODT protocol in this paper is superior to the existing method performance in energy consumption, delay and packet transmission rate.
