In this paper, a novel method is proposed to reduce the number of route misdirection to increase network throughput. This method increases the network throughput by accurately sending the packets from source node to destination node without any packet loss, which ensures Quality of Services (QoS) routing services. These metrics are used for making better routing decisions to avoid the packets being misrouted in the network. The proposed method operates under two phases: flow control and QoS routing phase. Wireless sensor network dynamically changes its topological structure since the path between source and destination nodes varies at the rapid instance of time. Hence, the flow control phase is used to adjust the packet flow through a proper link to reach its destination node. The flow control phase effectively designs an improved Random Waypoint Mobility model that utilizes three metrics for avoiding the packets being misdirected. In the second phase, the packets are routed through proper routes after avoiding the misdirected routes using an adaptive QoS routing protocol. This helps to increase the throughput of the network and this utilizes the three metrics for accurate identification of routes. The performance of the proposed method is evaluated the various metrics like network throughput (98.595 kbps), network lifetime (346 s) and delay (0.922 s). The proposed method is compared with existing QoS routing algorithms. The results show that the proposed method has improved its throughput level by reducing the total number of packets being misrouted in the network.

无线传感器网络中使用随机航路点移动模型的误导路线规避

在本文中,提出了一种新的方法来减少路由误导的数量以增加网络吞吐量。这种方法通过准确地将数据包从源节点发送到目标节点而没有任何数据包丢失来增加网络吞吐量,从而确保服务质量 (QoS) 路由服务。这些指标用于做出更好的路由决策,以避免数据包在网络中被错误路由。所提出的方法在两个阶段运行:流量控制和QoS路由阶段。无线传感器网络动态地改变其拓扑结构,因为源节点和目标节点之间的路径在快速实例中变化。因此,流控制阶段用于调整通过适当链路到达其目的地节点的数据包流。流量控制阶段有效地设计了改进的随机路点移动模型,该模型利用三个指标来避免数据包被误导。在第二阶段,在使用自适应 QoS 路由协议避免错误路由后,数据包通过正确的路由进行路由。这有助于增加网络的吞吐量,并利用三个指标来准确识别路由。所提出方法的性能通过网络吞吐量(98.595 kbps)、网络寿命(346 秒)和延迟(0.922 秒)等各种指标进行评估。所提出的方法与现有的QoS路由算法进行了比较。结果表明,所提出的方法通过减少网络中误路由的数据包总数提高了其吞吐量水平。
