| Abstract | The size of the carrier sensing range has a great impact on the network performance. Previous studies have focus on computing asymptotic optimum carrier sensing range using unrealistic interference models. In this paper, based on realistic interference model, we propose a framework to determine the optimum carrier sensing range of a network. By regarding the given network and the settings as input and modeling the interferences in wireless networks using transmission relation graph (TRG), our framework can compute a precise optimum carrier sensing range for the given network. Then we use our framework to investigate the changing rules of the optimum carrier sensing range of several types of wireless networks. Simulations are also performed using ns-2, and the results validate the effectiveness of our framework. |
