Paper Title
Gray Hole Attack In Manets

Mobile Ad hoc Network (MANETs) have become immensely popular due its simplicity, low cost, ease of deployment and wide application area. Routing in ad hoc network has always been challenging due to absence of any fixed infrastructure and most of the routing protocols assuming a trust based environment. Due to the simplicity of ad hoc wireless networks and usage of trust based routing policies, attackers find it more convenient to join the network and disturb the routing operations in the network. Gray hole attack is one of the popular attacks against mobile ad hoc networks (MANETs) where a malicious node agrees to participate in route formation but later on denies data forwarding. In this paper, an attempt has been made to understand the sensitivity of two prominent Ad hoc routing protocols viz Ad hoc On-demand Distance Vector Routing (AODV) and Dynamic Source Routing (DSR) when exposed to Gray Hole Attack.
