The design of routing protocols for mobile ad hoc networks (MANETs) is a complex task given the dynamic nature of such networks. Particular types of routing protocols are known as bioinspired. Related to theses, the algorithms based on Ant Colony Optimization (ACO), are particularly relevant. This work presents a new variant of AntOR, a multihop adaptive routing protocol based on AntHocNet which already has two versions: disjoint link routes (AntOR-DLR) and disjoint node (AntOR-DNR). The new protocol, called AntOR-RDLR, differs from AntOR-DLR in the pheromones updating process and the route discovery mechanism. The simulation results indicate that AntOR-RDLR improves their predecessors in all analyzed metrics.
