An Explanation for Unexpected 802.11 Outdoor Link-level Measurement Results

Giustiniano, D. Bianchi, G. Scalia, L. Tinnirello, I.
This is a hands-on paper. Very well written and interesting. It shows that the combination of atheros chipset and madwifi drivers present a weird effect because of the particular use of the diversity concept.

Performance Evaluation of R-ALOHA in Distributed Packet Radion Networks with Hard Real-Time Communications

Te-Kail Liu, John A. Silvester and Andreas Polydoros

They analyze R-Aloha, which is very similar to CSMA/ECA. And they also use markov chains, so the parallelisms arise. Nevertheless, since there is no reservation in CSMA/ECA, there are also some differences. Anyway, there is still many things I can learn and reuse in this paper. By the way, which is the difference between p[] and Pr{}?

Capture Effects of Wireless CSMA/CA Protocols in Rayleigh and Shadow Fading Channels

Jae Hyun Kim, Member, IEEE, and Jong Kyu Lee, Member, IEEE

The performance of CSMA/CA is computed, taking into account the capture effect. I was surprised that they also considered the case in which acks are ommitted.

Application Layer FEC in IPTV Services

M.Luby. T.Stockhammer, M.Watson

Forward Error Correction has many applications in IPTV distribution. I was thinking that it maybe also particularly useful for P2P live streaming.

Game Theory for Wireless Engineers

Allen MacKenzie, Luiz DaSilva

A superb book to get a flavor about what game theory is about.
