标题： Streaming multimedia over WMSNs: an online multipath routing protocol

摘要： 路由是无线多媒体传感器网络（WMSNs）面临的挑战，因为节点的能源限制和计算能力，以及传感器节点获取转发信息的方式，使得支持多媒体应用变得困难。在本文中，我们提出了一种在线多路径路由协议，该协议利用节点的位置在每跳进行转发决策。实时决策无需了解整个网络拓扑。该协议通过利用：(a) 智能贪婪转发方案选择下一跳，以及 (b) 回退转发方案绕过网络漏洞，实现负载均衡并最小化节点的能量消耗。将所提出的协议（方案）与TPGF和GPSR进行了性能比较。结果表明，我们的方案：(a) 通过不从某些特定节点耗尽能量来最大化整体网络寿命，(b) 通过使用路径上的最佳节点为视频流提供QoS传输，以及 (c) 在高密度WMSN中具有更好的可扩展性。 显示英文摘要

摘要： Routing is a challenge to Wireless Multimedia Sensor Networks (WMSNs) for supporting multimedia applications due to nodes' energy constraints and computational capabilities, and the ways sensor nodes obtain forwarding information. In this paper, we propose an online multipath routing protocol that uses nodes' positions to make forwarding decisions at each hop. Real-time decisions are made without any need to have the entire network topology knowledge. The protocol achieves load-balancing and minimises nodes' energy consumption by utilizing: (a) smart greedy forwarding scheme for selecting next hop, and (b) walking back forwarding scheme to bypass network holes. Performance comparisons of the proposed protocol (schemes) are made with TPGF and GPSR. The results show that our schemes: (a) maximise the overall network lifespan by not draining energy from some specific nodes, (b) provide QoS delivery for video streams by using best nodes along the route, and (c) scale better in high density WMSN.
