Enhance your understanding of Mobile IP, handover management, and seamless connectivity with this quiz designed to cover address assignment, mobility agents, handover types, and protocol mechanisms. Perfect for learners seeking to solidify their knowledge of mobile network protocols and smooth user experience in wireless communications.
In a Mobile IP network, which type of address allows a mobile node to keep communicating while moving between different networks without changing its identity?
Explanation: The home address enables a mobile node to maintain a constant network identity regardless of its current point of attachment. Temporary addresses are not used in Mobile IP as a permanent identifier, and network gateway is a network element, not an address for nodes. Source route refers to manual definition of pathways, not to node identity management.
What is the primary responsibility of a foreign agent in Mobile IP when a mobile node visits a foreign network?
Explanation: The foreign agent provides the care-of address and assists in forwarding incoming packets to the mobile node when it is away from its home network. Authentication is usually handled before agent services, while time stamp synchronization and storing preferences are not key functions of the foreign agent. The distractors reflect common networking terms, but do not address the main role of a foreign agent.
Which handover type is characterized by maintaining an ongoing communication session when a mobile device switches from one base station to another within the same network?
Explanation: Intra-system or horizontal handover keeps the session continuous while the device remains within the same network technology, such as moving between cells in a cellular network. Inter-network handover involves different network types, session-based is a generic term not specific to handovers, and cross-layer refers to operations across different network layers, not specifically handovers.
During mobility in Mobile IP, what is the purpose of the care-of address assigned to the mobile node while away from its home network?
Explanation: The care-of address allows the home agent to deliver data to the mobile node via tunneling when it is on a foreign network. Authentication is related to connection security, bandwidth reservation is handled by other mechanisms, and power management is unrelated to care-of addresses. The correct option covers the packet delivery aspect essential to Mobile IP.
In classic Mobile IP implementations, which issue describes inefficient routing where packets travel from the correspondent node to the home agent and then to the mobile node’s care-of address?
Explanation: Triangle routing refers to the situation where packets take a detour via the home agent instead of following the shortest route, resulting in inefficiency. Circular addressing and split horizon are unrelated network concepts, and direct tunneling is an enhancement to avoid this problem, not the issue itself. Only triangle routing accurately captures the described inefficiency.
