Abstract--Wireless Mesh Networks (WMNs) have emerged
recently as a promising technology for next-generation wireless
networking to provide wide variety of applications that cannot be
supported directly by other wireless networks. In WMNs, security
is turning out to be a major concern and little attention has
been paid to this topic by the research community. In this paper,
we investigate a serious security threat known as the selective
forwarding attack (gray hole attack). In a selective forwarding
attack, a malicious node refuses to forward all or a subset of
the packets it receives. Such selective dropping is challenging
to defend against. In this paper, we present an algorithm to
defend against selective forwarding attacks based on AODV
routing protocol. The first phase of the algorithm is Counter-
