Conclusions and Future Work
n Mesh networks: Gateways/APs are performance
bottlenecks
n MANET routing protocols, routing to closest AP, tend to
(temporarily) overload some APs
n TB can improve network performance by distributing
traffic more equally to all APs
n Future Work:
Ø Location of APs has major impact on performance
Ø IEEE 802.11 is poor protocol for APs, as they need to access
media more frequently than nodes
Ø MESH are more static, should we re-issue route discovery
periodically?
Ø Explore TB in our wireless mesh testbed, based on IEEE 802.11
