Abstract

The various reasons of failures that affect reliability of sensor nodes in addition to processing and transfer of large multimedia content (image, audio and video) have posed new challenges that are nowadays a real threat for routing protocols in Wireless Multimedia Sensor Networks (WMSNs), which aim to ensure flow delivery while guaranteeing QoS requirements. Moreover, extending network lifetime and maintaining network stability to cope with breaking links and topology changes (failures or sensor mobility), remain unsolved issues, particularly, during data transmission phase. Therefore, in this paper, we jointly consider multipath transmission, load balancing and fault tolerance, to enhance the reliability of transmitted data. We propose a Geographic Multipath routing protocol reinforced by Fault-Tolerant mechanism (GMFT). Theoricals results and those obtained from both simulation study and experiments on a real testbed demonstrate the validity and efficiency of our proposed protocol, and indicate that it is highly advised for multimedia transmission and network stability.

无线传感器网络中多媒体传输的容错机制

除了处理和传输大型多媒体内容(图像、音频和视频)外，影响传感器节点可靠性的各种故障原因对无线多媒体传感器网络(wmsn)中的路由协议提出了新的挑战，这些挑战是当今路由协议的真正威胁，其目的是确保流传输同时保证QoS要求。此外，延长网络生命周期和保持网络稳定性以应对链路断裂和拓扑变化(故障或传感器移动)，仍然是未解决的问题，特别是在数据传输阶段。因此，本文综合考虑了多径传输、负载均衡和容错等问题，以提高传输数据的可靠性。提出一种基于容错机制(GMFT)的地理多径路由协议。理论分析、仿真研究和实际测试结果均表明了该协议的有效性和高效性，对提高多媒体传输和网络稳定性具有重要意义。
