“…Despite this augmentation increases transmission payload and is referred to as channel coding. To enhance reliability, a combination of FEC and ARQ, known as Hybrid-ARQ (HARQ), can be utilized [34]. In this context, we consider ARQ policy named stop-and-wait.…”

The transmission of video stream over wireless networks is used by many applications and services, from the use of equipment in home communication networks to those carrying the video surveillance stream. Numerous technical challenges may arise when the unpredictable characteristics of the radio channel align or do not align with the stipulated requirements for transmission bandwidth and the necessary latency for transporting video data. All these challenges prevent users from experiencing smooth video streaming. Depending on the application scenarios, video service emphasis may vary according of Quality of Experience - QoE or parameter used traditionally in the networks, Quality of Service - QoS. The purpose of the research consists in optimization of the flow service, which ensures the adaptability of video communication to changes of conditions over the wireless computer network. As a result of a thorough analysis of the video playback characteristics related to the wireless channel, the most optimal approach in optimizing the quality of the video stream service over a wireless LAN requiring minimal modifications was identified, and namely system centric approach.

“…Automatic Repeat reQuest (ARQ) and Forward Error Correction (FEC) are two commonly used strategies to combat error in underwater transmission (Bin et al, 2008). ARQ which proposes retransmission (Kunal et al, 2010), are widely used in data communications system for error control as they are simple and provide high reliability. However, the throughput is not constant and decreases rapidly in high bit error rate cases (Lin et al, 1984).…”

“…However it has the drawback of using parity bit irrespective of the existence of errors. Reliability can be enhanced by combining FEC and ARQ, forming what is known as Hybrid-ARQ (HARQ) (Kunal et al, 2010).…”
