Decreasing broadcast in route discovery using vectors in mobile ad hoc networks
Mohammad Al-Shurman, Seong-Moo Yoo, Yoshito Kanamori · 2005
Wireless ad hoc networks routing protocols rely on traditional broadcast (flooding) in route establishment. Many nodes will rebroadcast the packet. Valuable network resources (e.g., battery power) can be consumed in flooding. In this paper, we will propose Vectorized Broadcast Routing (VBR) as an enhancement for LAR scheme 1 to reduce the broadcast. In case of discovery phase failure, VBR will enlarge the broadcast region again around the destination, unlike LAR where the network will be flooded with this request again. Simulation results show that VBR can decrease the number of routing packets by about one-third compared to LAR.
