Energy considerations for topology-unaware TDMA MAC protocols
Since the energy budget of mobile nodes is limited, the performance of a networking protocol for such users should be evaluated in terms of its energy efficiency, in addition to t...

Control Frame Shaping in Power Controlled and Directional MAC Protocols?
This paper discusses the ideal shapes of control frames (i.e., RTS/CTS frames) in the IEEE 802.11 MAC layer for efficient power control and directional beam forming in mobile ad h...

Improving the Performance of TCP in the Presence of Interacting UDP Flows in Ad Hoc Networks
In this paper, we study how fairness affects the performance of TCP over ad hoc networks with IEEE 802.11 at the MAC layer. The problem addressed is that the throughput of TCP flow...
