On the Performance of Access Strategies for MIMO Ad Hoc Networks
— In this paper, we address the impact of different access strategies in ad hoc networks with multiple antennas and MIMO communications. We employ a cross–layer designed MAC pr...

Circularity-Based Medium Access Control in Mobile Ad Hoc Networks
Abstract. The RTS/CTS access scheme, designed to reduce the number of collisions in a IEEE 802.11 network, is known to exhibit problems due to masked nodes, the imbalance between t...

Overhead analysis of query localization optimization and routing
Query localization is an improved extension of on-demand routing protocols for ad hoc networks. It makes use of prior routing histories to localize the query flood to a limited re...

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...
