Security always comes with a price in terms of performance degradation, which should be carefully quantified. This is especially the case for wireless ad hoc networks (WANETs), which offer communications over a shared wireless channel without any preexisting infrastructure. Forming end-to-end secure paths in such WANETs is more challenging than in conventional networks due to the lack of central authorities,...
IEEE 802.11n standard was a response to growing demands of high throughput multimedia applications over wireless networks. In spite of improvements by this protocol in physical layer rate by adding MIMO antennas to the pervious standards, some new features are mentioned in MAC layer to achieve high throughput. In this paper, we introduce an analytical model for IEEE 802.11n which analyzes different...
