Abstract: Wireless Mesh Networks (WMNs) have become
one of the important domains in wireless communications. They comprise of a
number of static wireless routers which form an access network for end users to
IP-based services. Unlike conventional Wireless Local Area Network (WLAN)
deployments, wireless mesh networks offer multihop routing, facilitating an
easy and cost-effective deployment. In this paper, an efficient and secure
multicast routing on such wireless mesh networks is concentrated. This paper
identifies the novel attacks against high throughput multicast protocols in
wireless mesh networks through Secure On-Demand Multicast Routing Protocol (S-ODMRP).
Recently, Sybil attack is observed to be the most harmful attack in WMNs, where
a node illegitimately claims multiple identities. This paper systematically
analyzes the threat posed by the Sybil attack to WMN. The Sybil attack is
encountered by the defense mechanism called Random Key Predistribution technique
(RKP). The performance of the proposed approach which integrates the S-ODMRP
and RKP is evaluated using the throughput performance metric. It is observed
from the experimental result that the proposed approach provides good security
against Sybil attack with very high throughput.
Keywords: Secure multicast routing, sybil attack, random
