| Summary: |
By using position-based routing in Y ANET, a vehicle makes forwarding decision
based on the geographic position of destination and single-hop neighbours. The
position of a destination is obtained through location service, while the positions of
single-hop neighbours are obtained through neighbour discovery. Location service is
a process where a destination sends its location updates towards location server
vehicles through hop-by-hop t(mvarding, and a source obtains this information tram
such location servers through location query. Neighbour discovery is a process where
a vehicle advertises its position to all neighbours within a broadcast range. In many
cases, adaptive neighbour discovery schemes are more suitable, but they suffer from
high channel load and stale neighbour information. For location service, floodingbased
model suffers from congestion. throughput and scalability problems due to
global flooding; flat hashing-based model uses global hash function and suffers from
network scalability due to delay, drop and overhead of location updates and queries;
hierarchical hashing-based model also uses a global hash function and suffers from
handover signalling, uneven load on higher level servers and query delay; hierarchical
quorum-based model. |
