    1. Zone Routing Protocol (ZRP) in NS-2 Shao-Cheng Wang Computer Networks Design and Testing Laboratory

    2. Outlines Basic ideas of ZRP Design diagram of ZRP package Utility scripts in ZRP package

    3. Routing protocols in ad-hoc networks Proactive Periodic routing updates Pros: little delay when route is needed Cons: lots of overhead in routing updates (especially in highly dynamic environment) Ex.: DSDV, WRP Reactive Source initiated/ on-demand approach Pros: no periodic routing update overhead Cons: still considerable control traffic for route searching (near flooding) long route query delay Ex.: DSR, AODV

    4. The ZRP Hybrid architecture Routing zone: Radius r Interior nodes and border nodes Inter-zone routing When the destination can not be found in the zone: Initiate route query bordercasting

    5. Design diagram of ZRP NS-2 package

    6. Hello and Link-State packets

    7. Route query and reply

    8. Installation and Operation NS-2.1b6 Follow the README example.tcl set opt(adhocRouting) ZRP Trace format in cmu-trace.cc (/zrp/support_code) Useful scripts (in /zrp/scripts) to get statistics from trace file Very useful debug switches in zrp.h

    9. Visualize the ZRP To do: Specify the OID in zrp.h Make sure debug16 in zrp.h is on. Output file: connections, hopsaway, NodeCoord Processing engine: drawquery.m

    17. Useful scripts In /zrp/scripts 2count_packets: echo 'received IARPS...' grep '^r [0-9]*\.[0-9]*.*IARP' $1 additionneur.cc process the outputs from 2count_packet and get statistics (overheads, sucessful rate…, etc.)

    19. Route query and reply (coming from outside)
