When reinstalling the key, associated parameters such as the incremental transmit packet number (nonce) and receive packet number (replay counter) are reset to their initial value.
Impersonating attack, where the attacker joins to the network and it can impersonate the original victim sensor node to receive packet, and traffic analysis, using wireless and cognitive features to listen in the entire spectrum.
The typical byte sequences which MCU read from RXFIFO to receive packet captured by HINT are similar to those of TXFIFO, except that there are 2 extra bytes at the end of each received packets, that is, Link Quality Indication (LQI) and Receive Signal Strength Indicator (RSSI).
In Fig. 1, the red and green blocks represent DL and UL subframes, respectively, while Arv, Req, Gnt, Trs, Rcv, Rly, Dpt, and Ack denote packet arrival, bandwidth request, bandwidth grant, packet transmit, packet receive, packet relay, packet departure, and packet acknowledge, respectively, where the subscripts represent the device types of event owner.
The example in Fig. 2 illustrates the distribution of transmission opportunities of sender s, in which node u11 will wake up to receive packet from s at time t1 and at least two nodes ui1 and ui2 will be awake to receive data at time t i. Fig. 2 Example of the single-hop transmission opportunity distribution for sender s.
Teams of two to four participants will receive packets of clues with destinations and challenges that need to be met.
We assume the simulation is event-based, and when the network works, cluster controllers receive packet-in messages with M/M/1/m queuing theory.
If intermediate nodes receive packets from the previous node on the path, they transmit the received packets in the allocated slot for each flow.
If any intermediate nodes receive packets from the previous node on the path, they transmit the received packet in the allocated slot.
At which time each node can receive packets on each channel.
Moreover, mesh routers can receive packets from only one sender at a time.
