摘要
针对无线传感器网络节点面临着随机攻击(失效)和选择性攻击,从而直接或间接地导致部分或整个网络的瓦解情况,对常见的3种无线传感器网络拓扑结构进行了分析,综合考虑泛洪算法和LEACH算法的路由思想,提出了一种新的路由算法。在节点选择下一跳时使用含有负载数的阈值函数进行有效调节,控制极少数节点负载数增长过快,从而提高网络的鲁棒性和抗毁性。网络性能分析及仿真结果表明,在校园无线传感器网络组网过程中应用该算法,网络的鲁棒性更好,抗毁能力大幅度提高。
The sensor nodes are facing the random failure and the selective attack all the time. Thus it will cause partial or entire network disintegrating. We have analyzed the three common kinds of wireless sensor network topology and overall considered routing thought of flooding algorithm and LEACH algorithm, then proposed a new routing algorithm. In the algorithm, threshold function is used to control that few nodes＇ load number grows excessively quickly. This is helpful in enhancing the network invulnerability. Finally the network performance analysis and the simulation result indicated that it can improve networks＇ robustness and invulnerability after applying this algorithm in the wireless sensor network in campus.
