EBM is to handle the problems found in other marking schemes regarding fairness among heterogeneous TCP flows through a tight feedback-loop operation and adaptation of the packet marking probability to network conditions.
First, as no new packets are necessarily generated during the encoding, the encoding complexity is dominated by generating the indices for the packets in each chunk, which does not incur any finite field operation or depend on the packet length L. In contrast, coded chunked codes incur a computational cost that is linear of L to generate a coded packet.
During real-world VANET operations, the payoff for the packet routing changes.
For normal HSN without key management, only the first two operations are possible, and the packet length of 46 bytes is also assumed.
For the network coding operation, node n i keeps the packet for later decoding of an encoded packet.
For example, when this unknown extracted silhouette is compared with a man's standing side view, then the unknown object is segmented into six parts, and when this is compared by armed view, then it is segmented into five parts and with same width and height ratios.After completing the silhouette comparison operation, the IP module creates the packet as shown in Figure 10.
In situations however wherein the destination is also another mote powered by energy harvesting (duty cycling using LPL) the packet send operation would consume significantly more energy since the sender has to wait for the receiver to wake up, all the time keeping the radio on and drawing a high amount of current.
The destination node performs the XOR operation on the coded packet with its own transmitted packet.
At the intermediate node, interflow coding using the XOR operation forms the coded packet ρ=ρ0⊕ρ1⊕ρ2⊕⋯ρ k−1).
If some processing operation is running when a new packet gets into the transceiver buffer, the process will be stopped and continued once the packet has been extracted from the transceiver and saved into the RAM memory.
