In this paper, we reveal performance of congestion-aware routing protocols that avoid traffic congestion and provides better throughput in IEEE 802.11 mesh networks. The mesh network of IEEE 802.11 consists several APs and each AP communicates each other using only radio channels. All wireless links between APs are established by using ad-hoc routing protocols. On the proposal, traffic load monitor function is implemented on each APs and it measures amount of in-coming traffic to the AP and inform other APs of measurement results in order to in order to avoid APs having a high traffic load in routes. Moreover, traffics are categorized as high priority class for real time application and low priority class for non-real time application as considering QoS, and the priority of sending traffics is controlled by using EDCA. Computer simulations were carried for evaluating the network performance with the proposed routing considering the traffic load balancing and QoS. The simulation results reveal that the proposed scheme can guarantee QoS in terms of throughput even if there is lot of best effort traffic and improve transmission delay performance. |
