A mobile ad hoc network (MANET) poses significant challenges such as route failure and end-to-end delay due to the decentralized nature of mobile ad hoc wireless networks, mobility of devices, and resource constraints. Motivated by this, in this work, a new routing protocol by implementing intelligent reflecting surfaces (IRSs) in MANET, called MRIRS, is proposed. The developed MRIRS investigates the role of IRS as an intermediate node which helps not only for multi-flow multi-path routing even in non-line-of-sight (NLoS) scenarios but also supports delay minimization in the route discovery phase and helps with interference-avoiding channel assignment to the primary users (PUs). Comparison in terms of packet delivery ratio (PDR) and end-to-end delay (PD) averaged on 40 topologies based on the same source and destination pair with 3 flows shows that MRIRS has an 8% improvement in PDR and 800 msec improvement in PD. In environments with 8 m/s average node speed, MRIRS shows 114.88 kbps improvement in terms of throughput where 15.97% link failure is recorded on average. In environments with 16 m/s, link failure is around 24% where it is almost 98% for other routing protocols.

MRIRS：智能反射表面辅助的移动自组织路由


由于移动自组织无线网络的分散性、设备的移动性和资源限制，移动自组织网络 (MANET) 带来了重大挑战，例如路由故障和端到端延迟。受此启发，在这项工作中，提出了一种通过在 MANET 中实现智能反射表面（IRS）的新路由协议，称为 MRIRS。开发的 MRIRS 研究了 IRS 作为中间节点的作用，它不仅有助于多流多路径路由，甚至在非视距 (NLoS) 场景中，而且还支持路由发现阶段的延迟最小化，并有助于为主用户（PU）分配避免干扰的信道。基于具有 3 个流的相同源和目标对的 40 个拓扑的平均数据包传输率 (PDR) 和端到端延迟 (PD) 的比较表明，MRIRS 在 PDR 方面提高了 8%，在传输速度方面提高了 800 毫秒。 PD。在平均节点速度为 8 m/s 的环境中，MRIRS 在吞吐量方面显示出 114.88 kbps 的改进，其中平均记录了 15.97% 的链路故障。在 16 m/s 的环境中，链路故障率约为 24%，而其他路由协议的链路故障率几乎为 98%。
