Reactive Protocols
Reasons:
Less control overhead
Better Scalability
Small or No routing tables
Dynamic Source Routing
Loop free protocol.
On demand routing protocol
Two mechanisms
Route Discovery
Route Maintenance
TORA Features
Link Reversal Algorithms
Adopt the height metrics
Requires time synchronization
Route Creation
A node will create a route if it has no downstream neighbors to the destination.
Broadcast a QRY packet.
Each node along the way to the source increase its height by one and rebroadcasts the QRY Packet with its updated heights
Delay
Route discovery latency
Queuing at interface queue
Retransmission delays
Propagation time
