In wireless ad hoc networks, multiple access interference is the limiting factor for the overall system performance. The lack of any central control unit necessitates a careful joint design of both, the physical and the MAC layer. Two promising technologies that address this problem are power control based cross-layer design and multiuser detection based cross-layer design. While approaches in the...
This paper addresses the fairness of Medium Access Control (MAC) protocols that are capable of handling interference on the physical layer to a varying extent. The variation addressed is thereby not based on different physical layer techniques applied, but on differing attribute levels of the same physical layer technique. This can e.g., be a varying number of antennas at each node in case of Multiple...
We present an extension to network simulator ns-2 for simulation of smart antennas with maximize gain beamforming. Unlike some of the previous work on this topic, we use a realistic beamforming model with detailed radiation patterns. Our antenna framework can be used to evaluate the characteristics of beamforming under various conditions and can be combined with any MAC protocol with smart antenna...
The deployment of wireless ad hoc networks faces severe limitations by mutual interference between wireless devices. In this work, we introduce a method to alleviate interference using a medium access control (MAC) layer exploiting multiuser detection (MUD). Instead of interference avoidance, the primary task of such a MAC layer is interference handling. To this end, we first identify link layer requirements...
