Abstract: Reliable link between the nodes playsvital role during the transmission of data in the routing protocols of Mobile Ad hoc Networks (MANETs). In this research paper, a routing protocol Link named Expiration Time based Routing Protocol (LETSRP)is proposed which uses Winternitz One-time Signature Scheme to checkthe authentication of transmitted data in the network. The packet sending node calculates maximum LET (Max LET), minimum LET (Min LET) and average LET (Avg LET) using greedy algorithm in our proposed solution. The number of sent packets dependson the available bandwidth. Various steps in implementation are repeated until all the packets reach the destination node. Simulations are done with variable number of nodes between10-20 nodes with mobility setting from 10 m/s to 20 m/s.
Keywords: Link expiration time (LET), Max LET, Min LET, Avg LET, LETSRP, AODV.
