The headache of wireless mesh networks. It seems that there is no magic formula to solve the problem. To limit interference while maximizing space reuse. The article suggests the use of beacons to separate traffic of the stations and mesh nodes. This beacons would also include SNR measurements, reservation information...

Maybe the solution lies in the use of smart antennae. I would comment it this afternoon with Pere.

SIP-BASED MOBILITY MANAGEMENT IN NEXT GENERATION NETWORKS

I see a parallelism betwen this paper and the previous one. In both cases a problem (mobility/multicast) has been atttempted to solve at the network layer for a long time and, now, efforts are focused at the application layer.

Network Coding for Efficient Multicast Routing in Wireless Ad-hoc Networks

Jingyao Zhang, Pingyi Fan, Member, IEEE, and Khaled Ben Letaief, Fellow, IEEE

Network coding might be efficient for multicast in adhoc and sensor networks. This papers deal with the problem of finding which nodes have to be encoders.

Topological Design of Interconnected LANs Using Hopfield Neural Networks

Shih-Tsung Yang and Anthony Ephremides

Hopfield Networks are applied to LAN interconnection for minimal delay.

Performance anomaly of 802.11b

Martin Heusse, Franck Rousseau, Gilles Berger-Sabbatel, Andrzej Duda

When a slow station shares the channel with fast stations, all the stations experiment low throughput. This problem is alleviated when using TCP, since the lost packets prevent that the TCP windows fully open.

This reference is also important. It is the one to cite when referring to short-term unfairness in DCF.

IEEE 802.16 Mesh Schedulers: Issues and Design Challenges

Najah A. Abu Ali,Abd-Elhamid M. Taha and Hossam S. Hassanein Hussein T. Mouftah

My intention was to get a feeling about mesh in 802.16... As I was reading, I was overwhelmed by the immense number of issues that one has to take into account... I wonder whether such a complex operation mechanisms would even work in a real implementation.
