          Ad hoc Networks
• Dynamically instantiated, impromptu multi-
  hop networks
• Possible erratic network topologies
• “an autonomous system of mobile routers
  connected by wireless links”-MANET WG
• Typical scenarios
  – Civil/Military emergencies
  – Lectures, conferences, Smart Dust
      Temporal-Mobility Graph

                                 Emergency
                                 Situation

                     Time
           How to solve this
• Routing Protocols:
  – On demand – Reactive
    • Ad hoc On demand Distance Vector (AODV)
    • Dynamic Source Routing (DSR)
  – Table Driven – Proactive
    • Global State Routing (GSR)
    • Fisheye State Routing (FSR)
    • Wireless Routing Protocol (WRP)
Squad and Base Scenario
              Our Solution
• Active network node designed for:
  – Small Devices
  – Routing Protocol Applications
• Self describing component based routing
  protocols
• Compatible with existing Active Nodes
System Overview
                Benefits
• Dynamic attachment points on fixed
  infrastructures
• Easy migration for nodes between
  networks
• Dynamic bridging support
              Conclusion
• Squad and Base scenario presents key
  problems
• Active technologies are the answer
• Ad hoc networks need these types of
  dynamic systems, to keep them ad hoc!!!!
        Future Work

•Build it!!
