Over the past decade, distributed hash table- (DHT-) based routing protocols have been adopted in wireless ad hoc networks (WANETs) to achieve scalability in the route discovery phase by avoiding the flooding mechanism. The security aspects of the routing protocols based on the DHT mechanism are crucial to address and have not been discussed in the existing literature. Therefore, addressing the security issues in DHT-based routing protocols would prevent the service disruption, decrease the traffic overhead, and reduce the packet loss in the network. In this paper, several security issues are identified and elaborated through an example scenario. Moreover, a novel DHT-based routing protocol is proposed that uses a digital signature and the user’s trust in order to swap securely the logical identifiers (LIDs). Trust between nodes is established by the user’s acquaintance and the first visual contact. The proposed protocol vindicates its effectiveness via simulation results in terms of computation time, normalized overhead, percent improvement, and packet delivery ratio.

无线自组织网络中基于DHT的路由范例中的安全数据分发

在过去的十年中，无线自组织网络（WANET）已采用基于分布式哈希表（DHT）的路由协议，以通过避免泛洪机制在路由发现阶段实现可伸缩性。基于DHT机制的路由协议的安全性对于解决这一问题至关重要，现有文献中并未对此进行讨论。因此，解决基于DHT的路由协议中的安全性问题将防止服务中断，减少流量开销并减少网络中的数据包丢失。在本文中，通过示例场景识别并阐述了几个安全问题。此外，提出了一种新颖的基于DHT的路由协议，该协议使用数字签名和用户信任来安全地交换逻辑标识符（LID）。节点之间的信任由用户的相识和第一次视觉接触建立。所提出的协议通过仿真结果证明了其有效性，包括计算时间，归一化开销，改进百分比和数据包传递率。
