Description:
Property: The source test case is that the routing table of A contains the route $p_{1}$ to B. The follow-up test case is that all route entries in A’s routing table are deleted, and then A requests to identify a new route $p_{2}$ to B. We should have the relation $p_{1} = p_{2}$

The follow-up test case is that the route from A to B is changed to a new one with $h_{2}$ hops, and then A sends the same data packet P to B. The resultant latency is $l_{2}$. We should have the relation that if $h_{1} >h_{2}$, then $l_{1} >l_{2}$

Description:
Property: The source test case is that A requests to transmit a data packet P to B (first transmission). The follow-up test case is that after a while, A requests to transmit the same packet P to B again (second transmission). We should have the relation (1) if the first transmission is successful, the second transmission should also be successful, or (2) if A only broadcasts a Route Request (RREQ) packet for searching a route to B but does not forward the packet at the first transmission, A should buffer the data packet at the second transmission

Description:
Property: The source test case is that A is put into the black list of B, and then A requests to transmit a data packet P to B. B will reply with a certain number ($n_{1}$) of RREP packets to A. The follow-up test case is that A is deleted from the black list of B, and then A requests to transmit the same packet P to B. B will reply with a certain number ($n_{2}$) of RREP packets to A. We should have the relation $n_{1} < n_{2}$
Source input: A is put into the black list of B, and then A requests to transmit a data packet P to B
