Reactive Approach
Proactive Approach
nVarious simulation
studies have shown that reactive protocols perform better in mobile ad
hoc networks than proactive ones.
–However, no single protocol works well in all environments.
–Which approach achieves a better trade-off depends on the traffic and mobility patterns.
