Position-aided Routing in Mobile Ad Hoc Networks
Outline of the Presentation
• Introduction to Ad Hoc Networks
• Routing in Ad Hoc Networks• Position-aided Routing• My Research Area
Position-aided Routing in Mobile Ad Hoc Networks
Wireless Network
• Access Technologies:– Bluetooth – (1Mbps, 3 meters)– IEEE 802.11b – (11Mbps, 100
meters)– IEEE 802.11a – (55 Mbps, 20
meters)
• Operating Modes:– Infrastructure Mode (Access
Point)– Ad Hoc Mode
Position-aided Routing in Mobile Ad Hoc Networks
Ad Hoc Network
• Ad Hoc Network is a dynamically created network that doesn’t rely on any fixed infrastructure for its operation but works in a shared wireless media.

Position-aided Routing in Mobile Ad Hoc Networks
Problems due to limited bandwidth
• Limited bandwidth requires the signaling traffic to be minimized in an Ad Hoc network.
• There is usually a trade off between the latency and the signaling traffic.
Position-aided Routing in Mobile Ad Hoc Networks
Approaches to Routing in Ad Hoc Networks
• Table driven routing protocols – Proactive in nature– Generate lot of signaling traffic– Less latency
• On demand routing protocols – Reactive in nature– Generate less signaling traffic– More latency
Position-aided Routing in Mobile Ad Hoc Networks
Position-aided Routing Protocols
• Use the location information about the other nodes from some positioning system like Global Positioning System (GPS).
• Results in reduction in signaling traffic.
• Reduction in latency.
