Dynamic Source Routing: Advantages Routes maintained only between nodes who need to communicate reduces overhead of route maintenance Route caching can further reduce route discovery overhead A single route discovery may yield many routes to the destination, due to intermediate nodes replying from local caches 58
Dynamic Source Routing: Disadvantages Packet header size grows with route length due to source routing Flood of route requests may potentially reach all nodes in the network Care must be taken to avoid collisions between route requests propagated by neighboring nodes insertion of random delays before forwarding RREQ Increased contention if too many route replies come back due to nodes replying using their local cache Route Reply Storm problem Reply storm may be eased by preventing a node from sending RREP if it hears another RREP with a shorter route 59

Dynamic Source Routing: Disadvantages<br />
Packet header size grows with route length due to<br />
source routing<br />
Flood of route requests may potentially reach all<br />
nodes in the network<br />
Care must be taken to avoid collisions between route<br />
requests propagated by neighboring nodes<br />
insertion of random delays before forwarding RREQ<br />
Increased contention if too many route replies come<br />
back due to nodes replying using their local cache<br />
Route Reply Storm problem<br />
Reply storm may be eased by preventing a node from<br />
sending RREP if it hears another RREP with a shorter route<br />
