【摘要】：無(wú)線(xiàn)傳感器網(wǎng)絡(luò)的生存性已成為部署傳感器網(wǎng)絡(luò)的一個(gè)重要考量因素�？缮娴臒o(wú)線(xiàn)傳感器網(wǎng)絡(luò)要求在多種攻擊并發(fā)的情況下能夠繼續(xù)提供關(guān)鍵服務(wù),基于此提出一種多種攻擊方式下的、基于簇的無(wú)線(xiàn)傳感器網(wǎng)絡(luò)生存性評(píng)估模型。因傳感器網(wǎng)絡(luò)的簇中存在多個(gè)遭受攻擊的節(jié)點(diǎn),為了更準(zhǔn)確地判定簇的狀態(tài),設(shè)計(jì)了一種閾值機(jī)制來(lái)觸發(fā)因多種攻擊而產(chǎn)生的狀態(tài)之間的轉(zhuǎn)移,準(zhǔn)確刻畫(huà)了網(wǎng)絡(luò)在遭遇攻擊后采取的反制措施。利用連續(xù)時(shí)間馬爾可夫鏈建立生存性評(píng)估模型并求解出可用性與生存性指標(biāo),分析了影響傳感器網(wǎng)絡(luò)生存性與可用性的若干因素。仿真結(jié)果表明,提高網(wǎng)絡(luò)修復(fù)率和攻擊響應(yīng)率能有效提高生存性與可用性,并且提出的模型能正確地區(qū)分網(wǎng)絡(luò)遭受的攻擊形式。
[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.
