+<h2>Leading Questions</h2>
+<ol>
+<li>In order to accommodate mobile users, what considerations should be taken when designing the network layer?</li>
+<li>From the standpoint of the network layers, what defines mobility of a network device?</li>
+<li>How important is the mobile node’s address?</li>
+<li>What supporting wired infrastructure is available for supporting wireless connections?</li>
+<li>What is ad hoc networking?</li>
+<li>What issues are involved in allowing a mobile user to maintain ongoing connections while moving between networks?</li>
+<li>What do the terms <em>home network</em>, <em>home agent</em>, <em>foreign</em> (or <em>visited</em>) network, <em>foreign agent</em>, and <em>correspondent</em> mean?</li>
+<li>Why should all traffic addressed to a mobile node’s permanent address be routed to the foreign network when the node is resident of a foreign network? How can this be done?</li>
+<li>What roles does a foreign agent play?</li>
+<li>What is a care-of-address?</li>
