The Mad-hoc team
ad-hoc
• formed for specific or immediate problems or needs
• fashioned from whatever is immediately available
ad-hoc
• no infrastructure
• increased reach
• increased connectivity

Ad-hoc routing protocolsPro-active (ex. STAR,TORA)
Re-active (ex. AODV, DSR)
Keeps track of all destinationsPeriodic updates
Request routes when needed
Only deals with used routes
AODV (Ad-hoc On demand Distance Vector)
High mobility
Loop free routes
Low byte overhead
Developed by Charles E. Perkins
A BD
AODV: A new node
C
Our addition (bi-directional requests)
A BD CE
AODV implementation
• Route table modifying process• Written in C under Linux using gcc• User space process
– no kernel modification– easy to install– portable
Open source
• GNU Public License - GPL– Free to copy, use and modify– May not be licensed by others
• First free implementation of AODV!• Other implementations soon
no use selling source code
Free implementation
Open source - benefits
•Development of source code•Spread usage of AODV
•Mad-hoc becomes well known•AODV becomes standard
Mad-hoc increases distance to competitors
Tested scenarios
• Multihop TCP & UDP support
• Quake gaming sessions• Cooperating team at Uppsala University
