Question

A new colony have been established on the moon. The colony must maintain constant communication from the Moon Base to the Earth ground control

1. To reduce communication overhead and cost, only a single highspeed communication link is established from the Moon Base colony to the Earth command center. Provide the best communication strategy to compress the bandwidth from the Moon Base colony to propagate the transmission to the Earth. Describe your solution and provide illustration to support your answer.

2. The communication from the Moon Base must be secured to the best. Describe the best strategy to secure the communication to avoid eavesdropping, signal jamming, and hacking. Describe your answer and provide examples in the form of tables and diagrams.

Answer 1

A,) We can use the bit-rate reduction to the data over the network which will ease our work of compressing the bandwidth while trasnmitting the same amount of the data over the network. Using tnormal or original representation would means that we are sending all the data as usual over the network. using the bit rate reduction would result in encoding the data with fewer bits and transmit it over the network. here we are representing the data that is most frequently occuring to the few bits by replacing it with the encoding method to represent the same bit using fewer bits.

B.)To avoid the hacking , eavesdropping etc of the data we should be using the proper connection protocol like TCP/IP protocol that ensure the connection is safe and we should use the technique like the encryption or hashing to scramble the data being send so that no one can understand other than the one it is meant to be . Using the proper secure channel and authentication method to access the data should be implemented.
