摘　　要：提出了一种基于Kolmogorov-Smirnoff(K-S)检验的节点自私行为检测算法,并结合对节点发送次数的检测进一步提高了检测速度和精度。该算法无需对无线信道参数进行假设,性能不受捕获效应的影响。仿真实验表明,该算法具有较快的检测速度和较低的误判率,性能明显优于经典的中心极限定理(CLT)检测算法和DOMINO检测算法。A new algorithm based on Kolmogorov-Smirnoff （K-S） test is proposed to detect the selfish behavior of nodes. Combined with the detection of transmitted number, the detection speed and precision are improved. The supposition of radio conditions are not needed and capture effect would not impact the performance of the algorithm. Simulation experiments show that the performance is superior to the CLT and DOMINO algorithm with more detection efficiency and lower misdiagnose probability.
