Write a program to simulate the behavior of the CSMA/CD protocol over Ethernet when ther are N stations ready to transmit while a frame is being transmitted. Your program should report the times when each station successfully starts sending its frame. Assume that a clock tick occurs every slot time (51.2 microsec) and a collison detection and sending of a jamming sequence takes one slot time. All frames are the maximum length allowed.
The token bucket algorithm is a popular method for traffic shaping (recapthe algorithm in textbook Ch. 5.3.2). A computer uses a token bucket with a capacity of 400megabytes (MB), and a rate of 10 MB per second. The machine starts generating 20 MB persecond continuously when the bucket contains 200 MB. How long will it take to send 1000 MB?
using c++ write a program program:- Suppose that you are receiving a packet number of a data travelling over a network in array. First of all input number of packets a data will be in. Received packets must be in an order and there will be difference of 4 among packet numbers. If there is any missing packet than display message packet missing. If no packets are missing but are not in order arrange the packets in an order.
A messaging system reads message as 4-digit positive integer d1d2d3d4 and stores encoding of the message e1e2e3e4 for security reason. The encoding process is as follows: ei = (di+i) mod 3 For example, if message is 4590, the encoded message is 2101. Read any arbitrary message and display the encoded message in the following format: Original message = Encoded message = language : C
We have intercepted a message that we need to decode. Luckily, we know that they use the letters A to Z, space, 0 to 9. We also know that when they encode messages they start by shifting the first letter once to the left, then shift the next twvo letters right twice, then the next three letters left 3 times, then the next four letters right 4 times, the next five letters left 5 times, and so on. a. If the message intercepted was HMMG2WEIAO what was the original message? b. What would we get if we encoded the phrase 2750H FRSC (the Os are zeros) using the given algorithm?
The token bucket algorithm is a popular method for traffic shaping. A computer uses a token bucket with acapacity of 400 megabytes (MB) and a rate of 10 MB/sec. The computer continuously generates20 MB/sec for transmission from time 0. Assume the bucket’s water level is 200 MB at time 0.1a. How long will it take to send 1000 MB? Show the steps.1b. Draw a figure showing how the bucket’s water level evolves

What is the propagation delay from A to B, that is the amount of time from when the first bit of the packet is transmitted at A, until it is received at B? b. What is the transmission time of the packet at A (the time from when the first bit of the packet is sent into the wire and the time at which the last bit is sent into the wire). c.

In computing, time scales usually store the current time as the number of seconds that have elapsed since the beginning of some “epoch”, which is an arbitrary date that determines the starting time. For example, the Network Time Protocol (NTP) uses an epoch of midnight on January 1st (GMT) 1900. The elapsed seconds since the epoch are stored in a 32-bit unsigned integer. In many embedded systems, it is more practical to just consider the current year. In this case, the format is often modified such that 0 corresponds to midnight on January 1stof the current year. If a clock that was initialized to 0 at midnight of 1 January 2020 currently has a count of 3665044 seconds, what day and time does it represent? (For example, your answer should be in the form June 6, 8:47:12 am) Show your work
Used C PLUS PLUS LANGUAGE. all instructions are given in question. Kindly follow it. When a message is transmitted in secret code over a transmission channel, it is usually sent as a sequence of bits, that is, 0s and 1s. Due to noise in the transmission channel, the transmitted message may become corrupted. That is, the message received at the destination is not the same as the message transmitted; some of the bits may have been changed. There are several techniques to check the validity of the transmitted message at the destination. One technique is to transmit the same message twice. At the destination, both copies of the message are compared bit by bit. If the corresponding bits are the same, the message received is error-free. Response Required: Write a program to check whether the message received at the destination is error-free. For simplicity, assume that the secret code representing the message is a sequence of digits (0 to 9) and the maximum length of the message is 250…
A temperature sensor that supports CoAP has an operating range of 0–1000 °F reports a reading every 5 s. The sensor has a precision of 1/100 °F. The sensor reports along with every temperature reading a time stamp using the ISO 8601 format (CCYY-MM-DDThh:mm:ss). (a) If the current temperature measured by the sensor is 342.5 °F, construct the payload of a CoAP message with the reading encoded in XML and then in JSON. (b) Assuming that the sensor consumes 3 nano-Joules per byte (character) transmitted over a wireless network, calculate the total energy required to transmit each message. Which of the two encoding schemes (XML or JSON) is more energy efficient? By what percentage? Compare the bandwidth utilization for the XML vs. JSON messages in bits per second assuming UTF-8 text encoding is being used.
Suppose that a 20-Mbps 802.11 LAN is transmitting 64-byte frames back-to-back over a radio channel with a bit error rate of 10−7 (i.e., the probability of a bit to flip duringthe transmission). How many frames per second will be damaged on average?(*hint: you would need to calculate the probability that a frame does not suffer any bit errors, thisis equivalent to the fraction of frames that do not suffer any bit errors on average.)
I am analysing a pcap file using Python and wireshark. Currently, I have it counting the number of packets I would like to count the number of SYN and ACK packets with this function? My main piece of code thus far is n is an int please show me how to write the code for this.
