I liked it. It's about something I had been thinking and I think that I can learn something from their work.

ANALYSIS OF RETRY LIMIT FOR SUPPORTING VOIP IN IEEE 802.11E EDCA WLANS
Byung Joon Oh
Not a outstanding paper. But we have to admit that we were not the first that came up with the idea of suppressing/reducing retransmissions.

A new MAC protocol ensuring the multimedia traffic QoS for CDMA networks
Loren Carrasco, Guillem Femenias, Felix Raja
I was curious about this paper from people from my Island. It remebered me to take a look at the on-off model.
I should find some additional information in this paper:
G. Bianchi and F. Borgonovo et al., “C-PRMA: A Centralized Packet Reservation Multiple Acces System for
Local Wireless Communications”, IEEE Transactions on Vehicular Technology, Vol. 46, No. 2, pp. 442–435,
1997.

Uplink RRM for conversational and interactive services in utra-fdd

I read it because it was referenced in the paper i was reviewing.

Do we need Header Compression for VoIP in Wireless LANs?
Rastin Pries, Andreas Maeder and Dirk Staehle
The athors use OpNet simulations to determine the maximum number of calls in IEEE 802.11b,g,e networks. It's a week paper but is so close to our research area that makes it a very interesting reading. I must remember to include references to G711 and G729 codecs in our article.

Multicast Routing in Wireless Mesh Networks: Minimum Cost Trees or Shortest Path Trees
Uyen Trang Nguyen and Jin Xu
The authors present different techniques to build trees for multicast in wireless mesh networks.
SPT: Shortest Path Tree -> The one used on the Internet
MCT: Minimum Cost Tree
MST: Minimum Steiner trees as in wired networks.
MNT: Minimum Number of Transmissions for wireless networks. It accounts for the fact that a wireless transmission can reach various nodes.
The authors conclude that the SPT is better for various reasons. However, it seems to me that MNT should present numerous advantages such as reduced contention and collision. And it definetely present battery saving benefits.

TCP Throughput Enhancement over Wireless Mesh Networks
Li-Ping Tung, Wei-Kuan Shih, Te-Chung Cho and Yeali S. Sun
The article explains the hidden and exposed terminal problems. Using simulations, the authors relate this two effects to tcp performance. Finally, a channel assignment algorithm is proposed that optimizes TCP performance.

On Extending IMS Services to WLANs
Ahmed Hasswa* Abd-Elhamid Taha† Hossam Hassanein*
A proposal to integrate WLAN and IMS using AS. I don't see the point in proposing an alternative to the 3GPP integration.
