The mobile ad hoc network is a type of wireless network characterized by mobile nodes without a centralized administration. Frequent variations of the topology and the nature of the radio links have a negative impact on the stability of the links. Indeed, the link quality deteriorates rapidly and link breaks become frequent. To overcome these problems, new forms of routing protocols are used as the MultiPath routing. In addition, routing protocols require the knowledge of the nodes neighborhood to build and manage routes. The neighbor discovery process is performed by a Hello protocol. The Hello protocol typically involves several parameters such as the packet’s period; node’s transmit power, node’s position and node’s battery level. The purpose of this paper is to change the behavior of ad hoc On demand Multi-path Distance Vector (AOMDV) routing protocol by considering the density of the nodes as well as the interference of the neighboring nodes. This selection of paths goes through two stages. In the first step, we study the impact of the neighbor discovery process to select a set of paths having a minimum number of neighboring nodes to diminish contention problems and interference rate. In the second step, the Interference Ratio (IR) metric is used to select the paths in which the nodes are surrounded by a minimum of interference. We choose for our study two proposed approaches based on AOMDV routing protocol. The first is called AOMDV_neighbor and considers the density parameter as a path metric. The second is called AOMDV_neighbor_IR which considers the interference rate (IR) between each node and its neighborhood as a path metric. We evaluate the proposed routing protocols performance under various NS2 simulation scenarios in a shadowing environment.

移动自组织网络是一种无线网络，其特征在于没有集中管理的移动节点。拓扑结构的频繁变化和无线电链路的性质会对链路的稳定性产生负面影响。确实，链路质量迅速恶化，并且链路中断变得频繁。为了克服这些问题，将新形式的路由协议用作MultiPath路由。另外，路由协议要求了解节点邻居以构建和管理路由。邻居发现过程由Hello协议执行。Hello协议通常涉及多个参数，例如数据包的周期。节点的发射功率，节点的位置和节点的电池电量。本文的目的是通过考虑节点的密度以及相邻节点的干扰来更改临时按需多径距离矢量（AOMDV）路由协议的行为。路径的选择经历两个阶段。在第一步中，我们研究邻居发现过程的影响，以选择一组具有最少数量的邻居节点的路径，以减少竞争问题和干扰率。在第二步中，干扰比（IR）度量用于选择节点被最小干扰围绕的路径。为了进行研究，我们选择了两种基于AOMDV路由协议的建议方法。第一个称为AOMDV_neighbor，并将密度参数视为路径量度。第二个称为AOMDV_neighbor_IR，它将每个节点与其邻居之间的干扰率（IR）视为路径度量。我们在阴影环境中评估了各种NS2仿真方案下拟议的路由协议性能。
