摘要： 基于IEEE802.16标准的WiMAX技术已成为宽带无线接入的主要技术，IEEE802.16标准没有规定调度和资源分配策略，网络运营商可以自行选择。根据用户需求并考虑信道条件的影响，提出基于NS2的扩展WiMAX系统级仿真平台，给出一种公平有效的调度与资源分配策略。仿真结果证明该策略可以满足多种服务流的QoS需求并最大化系统吞吐量。

Abstract: WiMAX technology which based on IEEE802.16 standard has become the dominant technique in broadband wireless access. IEEE802.16 standard leaves the choice of schedule and resource allocation schemes to the network operator. According to the users’ requirements and considering the channel conditions, this paper proposes an expanded WiMAX system-level simulation platform based on NS2 and gives a fair efficient schedule and resource allocation scheme. Simulation results prove that the scheme can meet the QoS requirements of different types of service flow and maximize the system through-output.

Key words: WiMAX system, system-level, NS2 simulation platform, schedule, resource allocation
