The above lemmas together suggest the following: To minimize the average packet decoding delay in error-free retransmissions, network-coded packets (each of which can be used to decode two source packets) should be retransmitted first, followed by pairs of network-coded packets (each of which can be used to decode three source packets), followed by source packets.
A chunk is a set of packets each of which is a linear combination of the input packets, and a chunked code is a collection of chunks.
The base station sends the code update in a sequence of packets, each of which includes the hash of the next packet to be sent.
In existing techniques, the selected gateways and the base station will be overloaded with packets, some of which will be left over, finally impacting the packet loss and retransmission, which will increase the response time.
In order to achieve the wave packet tracking, a new performance index is introduced with multiple moving target wave packets, each of which evolves under the field-free condition and satisfies intermediate/final conditions associated to the tracking point.
A packet-switched network, on the other hand, routes digital data in small pieces called packets, each of which proceeds independently through the network.
Because data are sent around the Internet in small packets, each of which can take a different route, the flow of information is hard to stop, even if much of the network is destroyed.
Recall that a video frame may consist of multiple packets each of which may require several retransmissions.
In a period of over 10 h, we collected a total of approximately 400,000 packets, 6000 of which were corrupted.
Below Fig. 8 indicates the network configuration diagram and anticipated paths of the packets, all of which are to be put into practice.
After the warm-up time, the source node tries to send 100 kbytes of data to the destination as a batch of 100 packets, each of which contain 1 kbyte of data.
