Abstract :
It has been shown that IEEE 802.11 DCF medium access control (MAC) protocol may not be suitable for multihop wireless networks due to its relatively low throughput and severely unfairness problems. A tokenpassing MAC protocol, named Ripple, has been proposed to enhance the throughput of DCF by utilizing spatial reuse. However, two perfect assumptions of dasiafixed-length data packetpsila and dasiaidentical interference range and transmission rangepsila in Ripple make it less practical in the real world. This paper proposes an Enhanced Ripple (E-Ripple) protocol aiming to remove the two restrictions. An analytical model is presented to estimate the performance of E-Ripple and the accuracy of the analysis is then verified via computer simulations. The results indicate that E-Ripple performs well in such a non-perfect environment.
