[ns] Why routing is performed on layer 2 in IEEE 802.11s wireless mesh networks standard

2008-05-19 Thread Ghada Al-Mashaqbeh
Dear all, I just want to find a reasonable justfications of why the IEEE 802.11s standard have specified that routing must take place at layer 2 of the protocol stack not layer 3? and which is better routing on layer 2 or layer 3 of the protocol stack? Thanks, Ghada
