Mobile Networking in ns</H1><P>This chapter describes the wireless model that was originally ported as CMU's Monarch group's mobility extension to . This chapter consists of two sections and several subsections. Thefirst section covers the original mobility model ported fromCMU/Monarch group. In this section, we cover the internals of amobilenode, routing mechanisms and network components that are used toconstruct the network stack for a mobilenode. The components that arecovered briefly are Channel, Network-interface, Radio propagationmodel, MAC protocols, Interface Queue, Link layer and Addressresolution protocol model (ARP). CMU trace support and Generation ofnode movement and traffic scenario files are also covered in thissection. The original CMU model allows simulation of pure wireless LANs ormultihop ad-hoc networks. Further extensions were made to this modelto allow combined simulation of wired and wireless networks. MobileIPwas also extended to the wireless model. These arediscussed in the second section of this chapter. <P><BR><HR><!--Table of Child-Links--><A NAME="CHILD_LINKS"><STRONG>Subsections</STRONG></A><UL><LI><A NAME="tex2html3892" HREF="node172.html"
