We consider the problem of fair rate control for wireless ad-hoc networks with time varying channel capacities. The interaction between links in wireless ad-hoc networks introduces additional constraints on the flow rate. A primal-dual algorithm that guarantees fair rate control is proved to be trajectory stable. Various fairness indexes are obtained by choosing the specified form of the utility functions, and the numerical results validate the effectiveness of the proposed algorithm.

Simple Rate Control Algorithm in TCP Network Using PSO

第二十九届中国控制会议

作者： tang meiqin,LIU Xiaohua,XIN Yalin School of Mathematics and Information,Ludong University,Yantai 264025,P.R.China

Power is inefficient due to the large peak-to-average power ratio（PAR）of the Orthogonal frequency division multi-plexing（OFDM）*** this paper,we propose an efficient power control algorithm for the OFDM systems,to achieve the optimum and fair resource utilization by maximizing a weighted sum *** objective function in this optimization problem is always nonconcave,which makes the problem difficult to *** make progress in solving this type of optimization problem using PSO（particle swarm optimization）.It’s proved that the proposed algorithm converges to the global optimal solutions in this *** examples show that our algorithm can guarantee the fast convergence and fairness within a few iterations.

Simple Rate Control Algorithm in TCP Network Using PSO

第25届中国控制会议

作者： tang meiqin, Wang Haiqiang,Long Chengnian,Guan Xinping Institute of Electrical Engineering, Yanshan University, Qinhuangdao, 066004 Institute of Information Science and Engineering, Yanshan University, Qinhuangdao, 066004

This paper considers the rate control problem with the objective of maximizing the total user utility. It focuses on the inelastic traffic and removes restrictive assumptions on utility function. We propose a simple distributed algorithm using PSO (particle swarm optimization) for achieving the optimal rates. In our algorithm, the network communicates to the user the number of congested links on the user’s path, and the user adjusts its rate accordingly, taking into account its utility function and the network congestion feedback. Numerical example shows that our algorithm converges to the optimum rates.
