Mobile ad hoc network is based upon multi-hop communication wherein the nodes themselves act as routers as well as source. The inherent characteristics of a MANET make it vulnerable to a variety of insider as well as outsider attacks. Most of the secure routing protocols do not focus on the insider attacks wherein certain adversarial nodes may launch a number of attacks on the routing protocol as well as on the data transmission by simply dropping the packets without forwarding them. The authors propose a secure hybrid routing protocol which combats the packet dropping attack carried on by an individual/colluding adversaries. It forms routes based upon a metric assigned to each node called weight/cost which indicates it's good/bad behavior.
