  1. An Ad Hoc NetworkTaxi Dispatch System E Huang Digital Technology Group Computer Laboratory University of Cambridge

  2. Mobile Ad Hoc Networks (MANETs) • Consist of a set of self-organized, decentralized, mobile hosts that roam at will and communicate directly with each other • We propose a novel application scenario in the form of a MANET dispatch system for taxis

  3. Financial Feasibility • Analysing the value proposition for primary players • Competing technologies • Cost comparisons • MANETs likely to be cheaper and easier to roll out

  4. Technical Feasibility • Mobility model based on Manhattan Grid System with realistic movement and traffic systems • Radio propagation model for microcells, based on a recursive path loss model with multipath fading and interference from other nodes

  5. Performance Evaluation • Performance evaluation made based on outage durations, connectivity, maximum outage time etc • Established relationships between performance and number of nodes, connection times, traffic congestion etc

  6. Conclusion • Allows us to establish physical bound for network connectivity independent of upper layer protocols • System is unsuitable for real time communication, however feasible for dispatch type applications • There are a number of business and technical risks to consider, however serves to highlight considerations for this type of application
