Routing protocols plays a key role in coherent use of resources in Internet of Things (IoT). The more efficient routing scheme is, the more efficiently will nodes communicate with each other. In this paper, we present presents an efficient cluster based routing protocol for IoT. The protocol aims at increasing lifetime and stability of networks. The paper introduces a new routing scheme Modified-Percentage LEACH Protocol based on existing protocol namely Percentage LEACH. Extra amount of energy wastage is alleviated by reducing communication between Cluster Heads (CHs) and sink. Thus, it increases the lifetime of sensor nodes in IoT communication networks. It is achieved by introducing threshold calculation on each CH, which is used as basic criteria for CH election and selection. The protocol also takes into account distance parameter of nodes from sink. This protocol helps plummeting energy wastage which results in more lifetime and high throughput. The depicted protocol is compared with its parent protocol and simulation results shows high throughput and outperforms its parent protocols.

物联网中使用距离感知的 PR-LEACH 路由方案的能量优化

路由协议在物联网 (IoT) 资源的连贯使用方面发挥着关键作用。路由方案越有效，节点之间的通信就越有效。在本文中，我们提出了一种高效的基于集群的物联网路由协议。该协议旨在增加网络的寿命和稳定性。本文在现有协议Percentage LEACH的基础上，介绍了一种新的路由方案Modified-Percentage LEACH协议。通过减少簇头 (CH) 和接收器之间的通信，减少了额外的能源浪费。因此，它增加了物联网通信网络中传感器节点的寿命。它是通过在每个 CH 上引入阈值计算来实现的，用作 CH 选举和选择的基本标准。该协议还考虑了节点到接收器的距离参数。该协议有助于减少能源浪费，从而延长使用寿命和提高吞吐量。所描述的协议与其父协议进行比较，仿真结果显示高吞吐量并优于其父协议。
