Geocasting in MANET Flooding-based protocol [Ko99Wmcsa] Graph-based protocol [Ko2000icnp,Ko2000tech] 240
Simple Flooding-Based Geocasting Use the basic flooding algorithm, where a packet sent by a geocast sender is flooded to all reachable nodes in the network The geocast region is tagged onto the geocast message When a node receives a geocast packet by the basic flooding protocol, the packet is delivered (to upper layers) only if the node’s location is within the geocast region 241

Simple Flooding-Based Geocasting<br />
Use the basic flooding algorithm, where a packet sent<br />
by a geocast sender is flooded to all reachable nodes<br />
in the network<br />
The geocast region is tagged onto the geocast<br />
message<br />
When a node receives a geocast packet by the basic<br />
flooding protocol, the packet is delivered (to upper<br />
layers) only if the node’s location is within the<br />
geocast region<br />
