Abstract

The user experience on watching live video sequences transmitted over a Flying Ad-Hoc Networks (FANETs) must be considered to drop packets in overloaded queues, in scenarios with high buffer overflow and packet loss rate. In this paper, we introduce a context-aware adaptation mechanism to manage overloaded buffers. More specifically, we propose a utility function to compute the dropping probability of each packet in overloaded queues based on video context information, such as frame importance, packet deadline, and sensing relevance. In this way, the proposed mechanism drops the packet that adds the minimum video distortion. Simulation evaluation shows that the proposed adaptation mechanism provides real-time multimedia dissemination with QoE support in a multi-hop, multi-flow, and mobile network environments.
飞行Ad-Hoc网络视频传播的上下文感知自适应机制
在高缓冲区溢出和丢包率的情况下,观看通过飞行自组织网络(fanet)传输的实时视频序列的用户体验必须考虑在过载队列中丢弃数据包。在本文中,我们引入了一种上下文感知的自适应机制来管理过载的缓冲区。更具体地说,我们提出了一个实用函数来计算重载队列中每个数据包的丢弃概率,该函数基于视频上下文信息,如帧重要性、数据包截止日期和感知相关性。以这种方式,提出的机制丢弃添加最小视频失真的数据包。仿真评估表明,该自适应机制能够在多跳、多流和移动网络环境下提供具有QoE支持的实时多媒体传播。
