Study Notes
Mobile Network Layer
- Mobile IP aims to provide location-independent routing of IP packets to mobile devices
- Assumptions of Mobile IP: mobile nodes change their point of attachment to the internet, mobile nodes use IP as the network layer protocol
- Requirements of Mobile IP: mobility, transparency to applications, and scalability
- Entities in Mobile IP: mobile nodes, home agents, foreign agents, and correspondent nodes
- Terminology in Mobile IP: home address, care-of address, binding update
- IP packet delivery in Mobile IP: triangular routing, tunnelling, and encapsulation
- Agent Advertisement and Discovery in Mobile IP: allows mobile nodes to discover available agents
- Registration in Mobile IP: mobile nodes register with a home agent and a foreign agent
- Tunneling in Mobile IP: encapsulation of IP packets for routing
- Encapsulation in Mobile IP: adding headers to IP packets for routing
- Optimization in Mobile IP: reducing overhead of Mobile IP
- Reserve Tunneling in Mobile IP: tunneling from correspondent node to mobile node
- Security in Mobile IP: protecting against unauthorized access and use
- IPv6 and Mobile IP: using IPv6 features for Mobile IP
- DHCP in Mobile IP: dynamic allocation of IP addresses
Mobile Adhoc Networks
- Routing in MANETs: finding routes between mobile nodes
- Destination Sequence Distance Vector (DSDV) algorithm: table-driven algorithm for MANETs
- Dynamic Source Routing (DSR) algorithm: on-demand algorithm for MANETs
- Hierarchical algorithms for MANETs: clustering, tree-based, and mesh-based algorithms
- Performance Metrics for MANETs: throughput, delay, packet loss, and jitter
Mobile Transport Layer
- Traditional TCP: does not adapt well to wireless networks
- Indirect TCP: TCP connection between mobile node and fixed host
- Snooping TCP: sniffing and caching TCP segments to improve performance
- Mobile TCP: TCP optimized for mobile networks
- Fast-retransmission TCP: quick retransmission of lost packets
- Transaction-oriented TCP: optimize for short transactions
