Although IEEE 802.11s introduces new interworking, routing and wireless frame forwarding at the link layer, the multi channel architecture receives less attention. In this paper we provide insights into the IEEE 802.11s standard and explain some channel assignment (CA) protocols which can be considered for wireless mesh networks to improve their performance by limiting the negative interference effects.
