Reliable one-hop broadcasting (ROB) in mobile ad hoc networks
Seungjin Park, Roopesh R. Palasdeokar · 2005
Although many algorithms are built on the existence of reliable one-hop broadcasting, reliability is very hard to achieve in MANETs due to the node mobility and hidden terminal problem. This paper proposes a new reliable one-hop broadcast algorithm, called Reliable One-Hop Broadcasting (ROB). Unlike other algorithms that consider the collisions as useless, ROB utilizes the collisions as an indication and measurement of completion of the broadcast. Our simulation results using ns-2 show that ROB outperforms unreliable broadcasting by up to 400% in terms of number of retransmissions when network density is high.
