This paper presents a new asynchronous power control with active link protection algorithm for wireless ad hoc networks. Previous works in this area have focused either on the asynchronous power control algorithms with no protection or synchronous power control with active link protection algorithms. Here, we fill the gap between these two approaches and propose a generalized asynchronous power control with active link protection algorithm. This new algorithm also includes the previous synchronous algorithms as special cases. We show that the proposed new algorithm can also provide the users with some information about network structure such as the total number of users in the network. We investigate the power-updating timing issues of this algorithm in theory as well as in real world applications. At the end, the performance of this algorithm is compared to that of a synchronous scheme by presenting some simulation and numerical results.
