After that, when the sender receives the ACK of (14, 20), it invokes the congestion control again because the duplicate ACK counter of packet 16 also reaches three.
MiniSec uses an incrementing counter (the packet number concatenated with the epoch number) as nonce; this is simple, allows multihop transmission (provided there is loose time-synchronisation in the system), and is resilient to loss.
In this manner, the duplicate ACK counter of packet 14 reaches three, and a fast retransmit and fast recovery events are invoked, in which the congestion window size is reduced to half.
Following ACKs for packets 17 and 19 increase the duplicate ACK counter of packets 14, 16, and 18.
A naked fat ham in orange bread crumbs jostled for space on the counter with packets of parsley sauce and marked-down broken biscuits.
Its front counter displays packets of Americana: Pringles potato chips, Slim Jim meat snacks, Rip Rolls and Reese's candy, Red Vine licorice, Ritz Crackers, Oreo cookies and Chips Ahoy chocolate chip cookies.
The counter-event packet is produced every 250 ms and includes the number of particle detections that are not transferred to the MDR, due to high particle count rates.
Because it is personal, rather than communal (like the home telephone or PC), the mobile telephone appeals to new customers: think of all those chattering teenagers, some of whom buy their telephone time over the counter, like a packet of crisps.
A broadcast message payload is appended with a nonce (which is a combination of the packet counter and the epoch number), and then encrypted using offset code-book (OCB) mode [15] of block cipher encryption.
In another example, collectors are used for storing RSSI and a packet counter, and an aggregator is used to determine the average RSSI in order to build an RSSI threshold filter.
