摘要
随着无线传感器网络的快速发展,其应用领域的广泛化和应用环境的复杂化导致不可避免地会出现各种干扰。采用适当的天线能有效降低干扰对无线传感器网络的影响,以达到低功耗和高可靠的目的。该文通过运用仿真软件OPNET模拟干扰源,分别模拟测试定向天线和全向天线下影响传输效率的误码率、吞吐量和端到端时延,并对比分析测试数据,结果表明在不同的应用场景中需要选择不同的天线以达到最佳传输效果。
Choosing suitable orientation or direction of antenna could reduce the influence of interference and reach the goal of low-power consumption and high-reliability. In this paper, through simulating interference source with Opnet, bit error rate, network throughput and end-to-end delay, the main parameters impacting antenna efficiency of transmission, Such as bit-error rate, network throughput, and end-to end delay, are tested and compared. The result shows that using suitable antenna in specific application could achieve the best efficiency.
