Jiangsu Province Communications Planning and Design Institute Limited Company, Nanjing 210009, China [email protected] Abstract. Traffic informationization is the embodiment of traffic modernization, networked and intelligentization. To speed up the development of ITS, devel‐ oping public Travel Information Service system with Mobile Internet technique is a practical application. As the latest development trend, WMN containing a lot of research hotspots. The routing mechanism is one of the key technology to be considered in IEEE802.16 mesh networks. This paper proposed a game theoret‐ ical based QoS-aware routing mechanism (GTQR). The main idea of GTQR is to periodically record node’s congestion state and forecast mainstream type next period. Then GTQR directional send MSH-DSCH message to make path selec‐ tion. GTQR sets a repeated game model to assess the advantage and disadvantage of path selection to optimize relaying strategy. Our simulation results demonstrate that GTQR performs better than other routing algorithms. Keywords: ITS · IEEE802.16 · Mesh networks · Game theoretical · QoS-aware · Routing mechanism

Introduction
The interline and sharing of traffic information is the precondition to implement ITS. Public Travel Information Service system technique has becoming a hot spot in domain of the research transportation information gradually. The announcement on that Mobile Internet-based traffic state and communication technologies are applied to the Travel Information Service is one of the important means to promote traffic information and will also greatly facilitate public travel. As the emerging technology of Mobile Internet, the WMN based on IEEE802.16 protocol has many researching space. The routing protocol of WMN hasn’t been finalized as a standard. The present ideas of routing algo‐ rithm mainly develop basing on the routing protocols of Ad Hoc network. Like Ad Hoc network, according to path generating sequence, the WMN routing protocols are divided into two types: proactive routing protocols and posterior routing protocols. The WMN routing protocols are also divided into source routing protocols and hop-by-hop routing protocols according to the way of transmission. It is necessary to design an appropriate routing protocol suiting for WMN. The relative representative work is OLSR (Optimized Link State Routing) proposed by Yang etc. in document [5].
