Performance evaluation of multi-antenna and multi-mode relays using a network simulator

In this paper, we propose the use of an existing opensource network simulator, WSNet, to evaluate the interest of using multi-mode relays in terms of energy consumption. We show that the combination of MIMO and multi-mode provides a solution to reduce global energy consumption, but that conclusions are really scenario-dependent. Moreover, we explain how a multi-mode MIMO terminal can improve these results using adaptive strategies.
