Mobile Ad hoc NETwork (MANET) comprises of nodes,

which are free to move randomly, yet cooperate to forward

packets between source and destination over a multi-hop

wireless network. Due to absence of any fi xed node, each

node acts as a router, providing routing capability for the

MANET. Various protocols for discovery of routes be-

tween any two MANET nodes have been designed. These

protocols are broadly categorized as on-demand proto-

cols and table driven protocols. Dynamic Source Routing

(DSR) and Ad-hoc On-Demand Distance Vector (AODV)

are the two most matured on-demand routing protocols,

while Optimized Link State Routing Protocol (OLSR)

and Topology Dissemination Based on Reverse-Path For-

warding (TBRPF) are the two most matured table driven

routing protocols. This paper proposes enhancements in

DSR to provide secured route discovery and improved
