What Are MANETs ?
Interconnected collection of wireless nodes
Nodes enter and leave over time
Nodes also act as routers; forward packets
No pre-established network infrastructure
No centralized administration
Communication using BlueTooth and WAP
Where Could We Use MANETs
Industrial and commercial networks
‘Anywhere’ communication
Military applications
Robust alternatives to cellular networks
Wearable and Ubiquitous computing
Remote satellite - based communication
Routing Protocols
Proactive protocols
Distributed shortest-path protocols
Maintain routes between every host pair at all times
Based on periodic updates
Reactive protocols
Determine route if and when needed
Source initiates route discovery
Hybrid protocols
Adaptive; Combination of proactive and reactive
