【摘要】 目前无线纳米传感网为大量应用提供了新的解决方案。纳米传感器资源有限,因此需要新的通信协议。简单的洪泛机制可以应用于基于电磁的无线纳米传感网,但是冗余广播增加了资源使用,影响性能并增加了能量消耗。PBF(Probabilistic Based Flooding)算法被提出并用于无线纳米传感网广播。使用Nano-sim进行了仿真,结果表明PBF算法减少了冗余重传,同时保持了良好的性能。更多还原

【Abstract】 Currently, wireless nanosensor networks offer new solutions for a wide range of applications. Nanosensors have limited resources, and therefore require new communication protocols. The simple flooding mechanism can be applied to electromagnetic-based wireless nanosensor networks. However, redundant broadcasting increases the use of resource, affects performance and increases energy consumption. PBF(Probability based Flooding) algorithm is proposed and used for wireless nanosensor network broadcasting. Simulation with Nano-sim indicates that the PBF algorithm could reduce redundant retransmissions while maintaining good performance.更多还原
