Match the column Mobility with the column Descriptions.

MobilityDescriptions
a) Macro-mobilityi) This is mobility within a MANET, caused by device mobility constantly changing the network topology.
b) Micro-mobilityii) This is mobility through a global network.
c) Ad hoc mobilityiii) This is mobility of a device in one single administrative domain of the global network.

  • A.a-ii, b-iii, c-i
  • B.a-iii, b-ii, c-i
  • C.a-i, b-ii, c-iii
  • D.a-i, b-iii, c-ii

Answer: A

The correct match is a-ii, b-iii, c-i. Macro-mobility is mobility through a global network (ii). Micro-mobility is the mobility of a device within one single administrative domain of the global network (iii). Ad hoc mobility is mobility within a MANET, caused by device mobility constantly changing the network topology (i). The other options swap at least one of these pairs. Mobile IP is the usual example of macro-mobility, in which a device keeps its address while moving between networks.
