According to the proposed SCTP standard [5], an SCTP sender need to detect the primary path error count (denoted as P 2errorcount) and conduct primary path handover once the value of P 2errorcount exceeds the maximum number of consecutive timeouts PathMaxRetrans [28].
where T max is the maximum delay time or the neighbor response timeout, d is distance to the current forwarding node, and R is the transmission range.
For example, such timeout could be set according to the Maximum number of hops we allow for each RREQ to be forwarded Let us denote, timeout as and Maximum number of hops as, assuming the average waiting time at each hop is.
The higher the variance, the larger the timeout.
The length of segment Lseg is 1500 bytes, the timeout T0 is 3 s and the maximum window size is 64 K bytes.
To guarantee that the new subflow is created before MPTCP connection timeouts, the minimum RTO value for MPTCP, i.e., 13 min (or 780 s) [25], is used to estimate the maximum distance between two cloudlet network regions before MPTCP retransmission timeout happens.
From the above discussion, we see that CMQ can be tuned using two parameters: qthresh (the maximum amount of messages in bytes allowed in the queue) and the timeout (the maximum waiting time a message stays in the queue before it is sent).
The Redskins called the timeout before Dallas challenged the reception.
If the call is overturned, the team keeps the timeout.
The boxplot portrayed in Figure 7 shows that the dismissal ratio realized by the EXACT strategy, neglecting dismissals from the penalty timeout, has a maximum which is 0.4119 lower than those of the heuristic strategies with ca. 0.43 as portrayed in Figure 8. Figure 8 shows the dismissal ratio with respect to the planning contingent size of the RAND strategy in a boxplot.
