智能电网中基于黑洞攻击检测的按需距离矢量路由

摘要

按需距离矢量路由 (Ad Hoc on-demand distance vector,AODV)广泛应用于智能电网;然而传统的AODV容易遭受黑洞攻击.为了检测和避免黑洞攻击,提出基于黑洞攻击检测的 AODV路由,记为 E-AODV.与传统的 AODV路由不同,E-AODV路由修改了路由回复(route reply,RREP)系统.E-AODV路由通过比较多个回复的序列号,检测是否存在黑洞攻击.一旦发现黑洞攻击,电表就向目的节点回复一条否定回复消息,进而防止恶意电表不良行为的蔓延.实验数据表明,相比于AODV,E-AODV在数据包传递率、吞吐量方面具有较好的性能.%Ad hoc on-demand distance vector (AODV) is commonly adopted for smart meter network and is considered.However, the default AODV is vulnerable to black hole attacks.To detect and avoid black hole at-tacks, detection of black hole attack-based AODV is proposed, which is marked as E-AODV.It modified the route reply (RREP) system based on AODV.By comparing sequence numbers from multiple replies, it detects the exist-ence of black hole behavior.After detection, the receiving meter sends a deny reply to the destination in order to avoid the effects of malicious meter.Extensive simulations are carried out in NS3 to evaluate the performance of E-AODV.Results show that E-AODV obtains considerately higher performance in terms of packet delivery ratio and throughput compared with the default AODV routing protocol.
