Abstract

We propose an enhanced Probabilistic Routing Protocol which using History of Encounter and Transitivity (E-PROPHET) routing protocol. The E-PROPHET introduces the contact frequency and contact duration into the routing protocols, which makes sure the message be forwarding to accurate next hop. Results of simulation indicate that the E-PROPHET saves the buffer space, improves the packet delivery ratio, and decreases the End-to-End delay.
