摘要/Abstract

摘要：

以业务到达时延最小化为目标，提出一种联合网络选择和业务分配的并行多接入算法．该算法中考虑了不同网络的可利用传输速率和网络时延，利用贝克曼变化思想证明了最优业务分配问题存在门限值，可以根据门限选择最小的接入网络集合获得最小时延．仿真结果表明在重负载情况下，该算法不仅能获得最大吞吐量，并且能够有效地降低业务的到达时延．

Abstract:

To minimize the traffic arrival delay, a joint network selection and traffic allocation algorithm is proposed for parallel multi-radio access transmission. The algorithm takes into account the available bit rates and network delays of different networks. Based on the Beckmann transformation method, we obtain the threshold for the optimal traffic allocation. According to such a threshold, a minimal subset of admitted networks can be chosen and traffic allocation among these networks can be done to achieve the minimum delay. Simulation results show that the proposed algorithm could improve the arrival delay effectively and guarantee the maximum throughput under the heavy load condition.

Key words: heterogeneous networks, parallel multi-radio access, minimizing delay, traffic allocation, threshold
