Performance comparison of hop count and radio aware path selection protocols in IEEE 802.11s WLAN mesh networks

IEEE 802.11s wireless LAN mesh network technology is the next step in the evolution of wireless architecture. A WLAN mesh network consists of WLAN devices with relay functions that communicate directly. In this type of networks, path selection is based on two protocols: RM-AODV and RAOLSR. These protocols use MAC addresses (layer 2 routing) and use a radio-aware routing metric for the calculation of paths. This paper presents a study of the performance of the proposed path selection algorithms under different scenarios and a comparison with hop count routing protocols AODV and OLSR.
