Adaptive Error Control Mechanism Based on Link Layer Frame Importance Valuation for Wireless Multimedia Sensor Networks

摘要

Wireless multimedia sensor networks (WMSNs) are a new and emerging type of wireless sensor networks (WSNs),which enable applications of multimedia captured through special sensors equipped with cameras or microphones etc.However,WMSNs face the challenges of transport reliability and energy consumption.In this paper,we propose an adaptive error control mechanism based on the importance of link-layer frame (AEC-LLFIV).The mathematical analysis shows that our AEC-LLFIV achieves better performance compared with Forward Error Correction (FEQ,Automatic Repeat Request (ARQ) and Chase combing Hybrid ARQ (HARQ),in terms of communication reliability and energy efficiency in WMSNs.
