【摘要】：无线传感器网络的生存性已成为部署传感器网络的一个重要考量因素。可生存的无线传感器网络要求在多种攻击并发的情况下能够继续提供关键服务,基于此提出一种多种攻击方式下的、基于簇的无线传感器网络生存性评估模型。因传感器网络的簇中存在多个遭受攻击的节点,为了更准确地判定簇的状态,设计了一种阈值机制来触发因多种攻击而产生的状态之间的转移,准确刻画了网络在遭遇攻击后采取的反制措施。利用连续时间马尔可夫链建立生存性评估模型并求解出可用性与生存性指标,分析了影响传感器网络生存性与可用性的若干因素。仿真结果表明,提高网络修复率和攻击响应率能有效提高生存性与可用性,并且提出的模型能正确地区分网络遭受的攻击形式。
[Abstract]:The survivability of wireless sensor networks (WSN) has become an important factor in the deployment of WSN. Survivable wireless sensor networks (WSNs) are required to continue to provide critical services under concurrent attacks. Based on this, a clust-based survivability evaluation model for wireless sensor networks with multiple attack modes is proposed. In order to determine the status of the cluster more accurately, a threshold mechanism is designed to trigger the transition between the states caused by multiple attacks, because there are many nodes under attack in the cluster of sensor networks. The countermeasures taken by the network after the attack are accurately described. The survivability evaluation model is established by continuous time Markov chain and the usability and survivability indexes are solved. Some factors affecting the survivability and usability of sensor networks are analyzed. The simulation results show that the proposed model can effectively improve the survivability and availability of the network by improving the network repair rate and the attack response rate, and the proposed model can correctly distinguish the attack forms suffered by the network.
