A hybrid routing algorithm against routing attacks in Mobile Adhoc Networks (MANETs)

Dynamically changing network conditions pose a challenge for routing in Mobile Adhoc Networks (MANETs). The network conditions like topology, node density, energy constraint makes difficult to decide which protocol suits best for the scenario. The routing in MANETs exploits Proactive and Reactive Routing. Proactive routing provides better packet delivery while Reactive routing has low overheads. Thus, Hybrid routing approach is needed to carry out the routing using both proactive and reactive approaches. The paper proposes a Hybrid Routing algorithm which utilizes the benefits of both reactive and proactive routing in MANETs. The protocol mainly focuses on trust factor of the node which uses frequency of the node and number of retransmissions from the node. The protocol changes its behavior according to different applications in MANETs.
