Conventional on-demand route discovery for ad hoc routing protocols
extensively use simple flooding, which could potentially lead to high
channel contention, causing redundant retransmissions and thus
excessive packet collisions in the network. This phenomenon has been
shown to greatly increase the network communication overhead and end to
end delay. This paper proposes a new probabilistic counter-based
method that can significantly reduce the number of RREQ packets
transmitted during route discovery operation. Our simulation results
reveal that equipping AODV routing protocol with the proposed
probabilistic counter-based route discovery method can result in
significant performance improvements in terms of routing overhead, MAC
collisions and end-to-end delay while still achieving a good
throughput.
