Mobile ad hoc networks (MANETs) are dynamically configurable wireless networks that have no fixed infrastructures and do not require predefined configurations. In MANETs, the high mobility of mobile nodes is a major cause of link failure. This paper proposes a reward-based routing protocol (RBRP) for MANETs. The proposed protocol uses the Q-learning route strategy to select a stable route to enhance system performance. The reward of a route is decided by four factors: hop count, bandwidth, power of battery, and speed of mobile nodes. Route discovery usually first finds multiple routes from the source node to the destination node. Then, the path with the greatest reward value for routing is selected. This study also compares the performance of the RBRP protocol with the well-known ad hoc on-demand distance vector (AODV) protocol. Simulation results show that the proposed RBRP outperforms the AODV protocol, especially in a high-mobility environment.
