Wireless Sensor Networks (WSNs) are increasingly used and will certainly be part of our everyday lives. Many routing protocols were designed with respect to WSNs capacities to allow the achievement of numerous applications. One of the not well investigated areas in WSNs is the queue management issue. The purpose of this paper is to present an analysis of(More)
This paper presents an energy efficient adaptive video compression scheme dedicated to wireless video sensor networks. This scheme based on the recent H.264/AVC standard operates using two modes, namely the standby mode and the rush mode. In the standby mode, frame rate is limited while image quality is maintained to a high level. In the rush mode, the(More)
This paper proposes a model to predict the energy consumption of a H.264/AVC intra-only based encoder designed for the wireless video sensor networks (WVSNs). Such model is of great interest in an energy-constrained context like the WVSN, where the video streams are processed prior to transmission. In fact, accounting for both processing's and(More)
In this paper, we propose a novel cross-layer approach for video delivery over Wireless Video Sensor Networks (WVSN)s. We adopt an energy efficient and adaptive video compression scheme dedicated to the WVSNs, based on the H.264/AVC video compression standard. The encoder operates using two modes. In the first mode, the nodes capture the scene following a(More)
