移动自组织网络中,由于节点的有限电量、高流动性和拓扑的频繁变化,路由是一个具有挑战性的问题,也使得网络管理、路由发现和不同的网络相关任务更加复杂。随着网络规模增加,通信负载会消耗更大比例的限制带宽,造成资源的浪费。其中,网络聚类是最具研究性的方法,选择能支持额外任务的合适节点,这样路由和组通信协议能在这种虚拟主干网之上高效地实现。提出了一种改进的LCR路由协议,一种为密集和大规模网络设计的分层路由协议。所提方法利用了方向机制,它限制了由路由的建立和保持所关联的区域,降低了路由任务中的控制阶段的数量。仿真结果表明,在不同场景中,所提改进协议大大地降低了能耗,并具有减少路由任务浪费带宽资源的能力。
In MANETs, routing is a challenging issue because of the limited capacity, mobility and topology of nodes. It also complicates network management, route discovery and different network-related tasks. As the size of the network increases, the traffic load will consume a greater percentage of the limited bandwidth, resulting in a waste of resources. Among them, the network clustering is the most research method, select the appropriate node to support additional tasks, so routing and group communication protocol can be efficiently implemented above this virtual backbone. An improved LCR routing protocol is proposed, a layered routing protocol designed for dense and large-scale networks. The proposed approach takes advantage of the direction mechanism, which limits the areas associated with the establishment and maintenance of routes and reduces the number of control phases in routing tasks. Simulation results show that in different scenarios, the proposed protocol greatly reduces energy consumption and reduces the ability of routing tasks to waste bandwidth resources.
