DSSSB TGT CS 2023 Shift 2 – Question 184

Match the column Mobility with the column Descriptions.

• a-ii, b-iii, c-i
• a-iii, b-ii, c-i
• a-i, b-ii, c-iii
• a-i, b-iii, c-ii

In mobile networks and pervasive computing:
– a) Macro-mobility: Refers to movement between different administrative domains across a global or inter-network infrastructure (handled by protocols like Mobile IP). Matches with ii) This is mobility through a global network.
– b) Micro-mobility: Refers to local movement within a single subnet or single administrative domain without triggering global registration updates (handled by schemes like Cellular IP, HAWAII). Matches with iii) This is mobility of a device in one single administrative domain of the global network.
– c) Ad hoc mobility: Refers to movement of nodes in a Mobile Ad-hoc Network (MANET) where devices communicate peer-to-peer and dynamic topology changes occur continuously without fixed infrastructure. Matches with i) This is mobility within a MANET, caused by device mobility constantly changing the network topology.

Hence, the correct matching is: a-ii, b-iii, c-i.
