In this paper, we propose a new routing protocol for mobile ad-hoc networks (MANET), which have attracted considerable attentions in recent years as a tool to realize flexible and robust communication environments in many critical application fields. The proposed protocol, called LQ-routing, is a proactive routing protocol based on the Q-routing protocol which was originally proposed for conventional wired networks. In order to reflect the mobility of hosts to the routing decision, which would cause frequent connection and disconnection of communication links between nearby hosts, we introduce the notion of lifetime to represent the stability of routes connecting to the destination. The performance of the proposed routing scheme is experimentally evaluated by using NS-2. The result of simulation indicates that by introducing the notion of lifetime to a simple combination of previous proactive routing scheme DSDV and the Q-routing, we could improve the performance of DSDV in terms of the packet loss rate and the average packet delay.
