  6. Time Line Seminar Phase Titles of seminar papers today Assignment at the end of this meeting 45min presentation starting Dec, 2003 Reading Class Phase Starts next week We discuss relevant topics for this project Homework for next week: What do you need to know about Computer Networks to design a mobile ad hoc network? And how do you get this information? • Kick-off Meeting • 1-day event at beginning of Jan, 2004 • Costumer-vendor situation: • We specify our needs • You state your product features • You sell, we buy…(best case scenario) • At the end of this meeting, you have • divided the task in modules • specified the module interfaces • assigned your work • coordinated your team • set up the road map of the project • Product • Available in July, 2004 • Product presentation, end of summer semester `04

  7. Scheduling Weekly meetings Tuesday slot, 09:15-10:45, F2.221 (every week) Reading Class Starts next week on the weekly meeting slot Seminar Phase starts 48th week (Nov 24) on two of the following slots Tue, 09:15-10:45, F2.221 Wed, 18:00-19:30, F0.530 Fri, 16:00-17:30, F1.110 Or starts 49th week (Dec 01) on three of the above slots Kick-off Meeting Suggestion: Fri Jan 9th, 2004. Starting at 9:15

  8. The Project Goals • Design and implement a mobile ad-hoc networks based on W-LAN • Design and implement a distributed data base within the MANET • Use efficient algorithms and data structures for stability and efficiency

  9. Motivation I • It is a nice warm day in the University Cafe… • All the students • are happy, drinking some coffee, discussing which project group to attend. • When suddenly somebody switches on his laptop • … and surfs the Internet while having a cup of coffee • … obviously somewhere there is a W-LAN base station

  10. Motivation II • The next day … • … more students • … connect to W-LAN • But some of them • … have severe connection problems • … Something must be done

  11. Motivation III • So they move closer to the base station • … and closer • The lucky ones establish a connection on the stairway • The others can not connect and waste some time ...

  12. Motivation IV • … and so they live unhappily together until • … some day a project group implements a • Mobile Ad-Hoc Network based on Wireless LAN • … and saves the day. • Now some • … act as client and router and shared their bandwidth to connect others

  13. The Project Methods • Design and implement a mobile ad-hoc networks based on W-LAN • Use IEEE 802.11 standard protocol and IP • If possible reuse other LINUX based MANETs • Design it, Implement it and perform field studies with the laptop computers of the project group • Design and implement a distributed data base within the MANET • Use peer based data-management techniques, mobile transaction protocols, data placement/caching strategies • Interact with the routing algorithm and retrieve node-based routing information • Use peer based data-management techniques, data placement/caching strategies • Use efficient algorithms and data structures for stability and efficiency • Use hierarchical clustering for bounding the impact of dynamics and mobility • Apply consistent caching algorith for the database • Use a hierarchical zone based link state routing service • Provide real world data by simulation • Provide a „proof-of-concept“-implementation of the Paderborn MANET (PaMANet)

  14. The PaMANet (Paderborn Mobile Ad-Hoc Network) Application Layer TCP/UDP IPv6 ESS Distributed Data Baseusing Consistent Hashing SWT Location service & Route Construction Application Layer MUA Transport Layer Routing using Cluster Addresses MUA ESS Routing Layer Hierarchical Clustering MUA Medium Access Control (MAC) Layer Link selection for ad-hoc mode of W-LAN cards ESS IEEE 802.11 Physical Layer Radio communication

  15. Reading Class Topics • Computer Networks - Problems and Hints • Mobile Ad Hoc Networks - Specifics and recent approaches • Theory of Mobile Ad Hoc Networks • MANET-Routing: What happened so far. • P2P-Networking and Web-Caching: What is it and how does it help us? • Distributed XML Databases: Replication, Caching, XML, Logical XPath Evaluation • The PaMANet.
