Description

In wired and wireless contexts where users must transport their mobile devices across various LAN subnets, mobile IP is most frequently observed. Use cases include roaming across competing wireless networks such IP over DVB, WLAN, WiMAX, and BWA. Since cellular systems like 3G offer their own data link layer handover and roaming procedures, mobile IP is not necessary to guarantee transparency when Internet users move between cellular towers. To enable seamless IP mobility between several packet data serving node (PDSN) domains, it is frequently utilised in 3G systems. Mobile IP is a standard communications protocol developed by the Internet Engineering Task Force (IETF) that enables users of mobile devices to switch between networks while preserving permanent IP address. The main goals of this book are to introduce fundamental ideas and approaches for mobile communication and to lay a platform for further study and investigation in the area of communication engineering.
