智能电网中基于黑洞攻击检测的AODV路由

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。

Detection of Black Hole Attack-based AODV in Smart Meter Network

Ad hoc On-Demand Distance Vector (AODV) is commonly adopted for smart meter network and is considered in our paper. However, the default AODV is vulnerable to black hole attacks. To detect and avoid black hole attacks, detection of black hole attack-based AODV is proposed in this paper, 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 existence 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.
