Disadvantages of Piggybacking

Networking Communication

Sliding window algorithms are methods of flow control for network data transfer. The data link layer uses a sender to have more than one acknowledgment packet at a time, which improves network throughput. Both the sender and receiver maintain a finite-size buffer to hold outgoing and incoming packets from the other side. Every packet sent by the sender must be acknowledged by the receiver. The sender maintains a timer for every packet sent, and any packet unacknowledged at a certain time is resent. The sender may send a whole window of packets before receiving an acknowledgment for the first packet in the window. This results in higher transfer rates, as the sender may send multiple packets without waiting for each packet’s acknowledgment. The receiver advertises a window size that tells the sender not to fill up the receiver buffers....

How To Increase Network Efficiency?

Efficiency can also be improved by making use of the Full-duplex transmission mode. Full Duplex transmission is a two-way directional communication simultaneously which means that it can communicate in both directions, just like we are using two half-duplex transmission nodes. It provides better performance than simple transmission modes and half-duplex transmission modes....

Why Piggybacking?

Efficiency can also be improved by making use of full-duplex transmission. Full Duplex transmission is a transmission that happens with the help of two half-duplex transmissions which helps in communication in both directions. Full Duplex Transmission is better than both simplex and half-duplex transmission modes....

Advantages of Piggybacking

The major advantage of piggybacking is the better use of available channel bandwidth. This happens because an acknowledgment frame needs does not to be sent separately. Usage cost reduction. Improves latency of data transfer. To avoid the delay and rebroadcast of frame transmission, piggybacking uses a very short-duration timer....

Disadvantages of Piggybacking

The disadvantage of piggybacking is the additional complexity. If the data link layer waits long before transmitting the acknowledgment (blocks the ACK for some time), the frame will rebroadcast....

Conclusion

There is a dispute as to whether this is a legal or illegal activity, but piggybacking is still a dark side of Wi-Fi. Cyber-terrorist attacks in India are a clear reminder that we cannot control incidents occurring anywhere in the world or control unsecured Wi-Fi networks. So it is the responsibility of the owner and administrator to secure their wireless connection....
