无线传感器网络中结合MAC层和主动节点的优化目标跟踪方法

An Optimize-Aware Target Tracking Method with Combine MAC layer and Active Nodes in Wireless Sensor Networks

Amir Javadpour

摘要:

无线传感器网络是由具有特定目标的不同大小的节点组成的网络。跟踪应用在无线传感器网络中非常重要。本研究提出了一种方法,以减少在无线传感器网络的能量消耗,考虑目标跟踪。提出了一种基于MAC层的预测方法,该方法利用MAC层的媒体访问控制机制,使少数节点处于活动状态跟踪目标,而其余节点则处于休眠状态。通过减少参与目标跟踪的节点数量和仅激活有限数量的必要节点来减少能量消耗。实验结果表明,该算法在不同通信距离下的能量消耗、节点数对能量消耗的影响、通信距离下参与跟踪的节点数以及目标丢失等情况下,都具有比同类算法更好的性能。这意味着所提出的方法更优越,更有效。当目标进入模拟区域时,网络节点通过所提出的方法(这是最优方法)识别目标节点,并在目标节点位于模拟区域内时对其进行跟踪。性能标准,包括能源,其他节点,和吞吐量在模拟中使用。实验结果表明,该方法具有最优性能,降低了网络跟踪过程中的能量消耗。仿真结果表明,与已有方法相比,该方法在提高目标跟踪精度的同时,在可接受的范围内降低了能量消耗。关键词:主动节点,MAC层,能量效率,目标跟踪,无线传感器网络,目标跟踪。

英文摘要:

Wireless Sensor Network WSN is consisted of nodes with different sizes and a specific goal. Tracking applications are very important in WSNs. This study proposes a method for reducing energy consumption in WSNs, considering target tracking. A prediction method is also presented with the help of MAC Medium Access Control layer in which a few number of nodes are in active mode to track the target while the rest of the nodes are switched into sleeping mode. Energy consumption was reduced by decreasing the number of nodes involved in target tracking and activating merely a limited number of necessary nodes. The conducted experiments suggest that the proposed algorithm has a much better performance compared to similar algorithms in different conditions, including energy consumption in different communication ranges, effect of the number of nodes on energy consumption, the number of nodes involved in tracking in terms of communication range, and losing the target. This means the proposed method is superior and more efficient. When the target enters the simulation area, nodes of the network identify the target node through the proposed method (which is the optimum method) and track it as long as it is inside the simulation area. Performance criteria, including energy, other nodes, and throughput were used in simulation. The results showed that the proposed method has the optimum performance and reduces energy consumption of the network during tracking. The results of the simulation showed that the proposed method reduces energy consumption to an acceptable extent, compared to previous methods, in addition to increasing the accuracy of target tracking. Keywords: Active nodes, MAC layer, Energy efficiency, Target tracking, Wireless sensor networks, Target tracking.
