One of the main challenges in wireless networks is addressing the unreliability of the wireless links, and providing reliable transmissions. Two important sources of errors in wireless transmissions are noise and interference. In order to address the errors due to noise, forward error correction methods can be used, in which redundancy is added to the packets to detect and correct the bit errors....
As the popularity of wireless devices (e.g. smartphones and tablets) increases, watching videos over the Internet is becoming a main device application. Two important challenges in wireless communications are the unreliability of the wireless links and the interference among the wireless links. In order to exploit reliable video multicast, forward error correction and network coding can be used. In...
Reliable packet transmission over error-prone wireless networks has received a lot of attention from the research community. In this paper, instead of using simple packet retransmissions to provide reliability, we consider a novel retransmission approach, which is based on the importance of bits (symbols). We study the problem of maximizing the total gain in the case of partial data delivery in error-prone...
Network Coding (NC) techniques have received a lot of attention from the research community for providing reliable broadcasting in error-prone wireless networks. The most common NC approach is segment coding, in which the packets are partitioned into segments, and linear NC is performed inside each segment. In order to increase the throughput of NC and decrease the decoding delay, dynamic coding schemes...
