The transmission opportunity (TXOP) is a novel mechanism, proposed by Task Group "e", for burst packet transmission within IEEE 802.11 wireless networks. However, its use is not optimized. In this paper an Enhanced TXOP scheme is proposed to exploit more effectively TXOP limits and increase system efficiency. The performance of ETXOP is evaluated from simulation based studies realized by...
