Cross-Layer Forward Error Control for Reliable Transfer in Wireless Multimedia Sensor Networks

Abstract

A cross-layer forward error control (FEC) scheme for wireless multimedia sensor networks (WMSNs) is proposed in this paper. Employing a novel fountain code so called iterative joint source-channel fountain code (ISCFC), this cross-layer FEC scheme joint exploits the physical layer, transport layer and the application layer FEC approaches, and is capable of offering strong bit error correction capability as well as overcoming the packet loss in the multi-hop wireless communication.
