Abstract

Reference [1] showed that wireless networks with capacity scalable with the number of nodes, n, are achievable in theory. The transport capacity scales as θ √ (n), while the capacity scales as θ (n). Reference [2], on the other hand, showed that the capacity of IEEE 802.11 networks does not scale with n due to its carrier sensing mechanism. The previous work, however, has not considered the use of power control. The main contributions of this paper are two-fold: 1) the demonstration that 802.11 networks are scalable with power control; 2) however, with power control, an enhanced MAC protocol called Selective Disregard of NAVs (SDN) can achieve substantially higher capacity. Specifically, capacity within 90% of the theoretical optimal capacity of infrastructure networks is achievable.
