Channel variability and a high level of noise lead to a significant probability of packet loss in many underwater networks. Techniques based on packet-level Forward Error Correction (FEC), such as Reed Solomon (RS) codes, can be used to offer effective protection against excessive packet losses that would be generated by noise. In this paper, we propose a new error recovery scheme based on RS codes...
This paper proposes a cross-layer approach called routing-aware multiple description coding with multipath transport to support video communications over mobile ad-hoc networks. This approach establishes a packet loss model based on the MAC access mechanism and network parameters, and utilizes it along with the routing messages from multipath routing to estimate the packet loss probability of transmitted...
Scalable video can be used to provide video streaming reliably to an heterogeneous set of receivers with different subscription levels. However, the performance of such schemes can be highly affected by scheduling constraints and unreliable feedback. Network coding, on the other hand, has been shown to reduce scheduling and prioritization problems and to perform well in wireless scenarios with perfect...
It is a challenge that using multipath transmit packets based on network coding in wireless mesh networks (WMNs). This paper proposes a mechanism that naturally adds network coding to multipath routing network systems. In the mechanism, network coding is compatible with improved multipath TCP (MPTCP). The destination feedback the degree of freedom of encoding block, and delays of packet delivery minimize...
