  1. Routing in Ad Hoc Networks Abhinav Gupta Supervisor Dr. Carey Williamson

  2. Outline of the Presentation • Introduction to Ad Hoc Networks • Routing in Ad Hoc Networks • Position-aided Routing • My Research Area

  3. 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

  4. 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.

  5. Ad Hoc Network

  6. Routing Problems in Ad Hoc Networks • Mobility of the nodes • Limitations on bandwidth • Limitations on power (battery) • Security

  19. 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.

  20. 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

  21. 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.
