| 中文摘要 | 文章结合无线传感器网络(WSN)中流量分布的向心性特点,借鉴物理学中势能场的概念与机理,提出一种开放的路由协议实现框架。利用不同的网络参数构造不同的"虚拟势能场",叠加后形成的复合势能场将驱动数据分组沿着势场梯度变化最快的方向移动,一方面可以最终将网络中的数据分组汇聚于目的节点,实现路由协议的基本功能;同时,在动态时变"虚拟势能场"的调节下,还可以为路由协议附加各种有利于实现其他优化目标的策略与属性,如能耗均衡、拥塞避免、支持服务质量保障和利于数据聚合等,在无线传感器网络中实现多策略路由。作为例子,文章提出了一个基于势能场的提供实时传输的路由协议,它能在严格保障实时分组获得最小化端到端延迟的前提下,有效缓解网络拥塞,提高全网吞吐量。; In this paper, motivated by the centralized traffic pattern in the Wireless Sensor Network(WSN), we propose a unified implementation framework for routing protocols based on the concept of potential field in the physics.Utilizing various parameters and factors, the multi-strategy routing protocol constructs different virtual potential fields, which move the data packets along the direction of the steepest gradient in the field.In consequence, the traffic is aggregated in the Sink node which satisfies the basic requirements of routing, while the dynamic time-variant field provides kinds of additional strategies and attributes for optimization purposes of the protocols.These optimization targets include energy balance, congestion control, QoS support and data aggregation, all of which achieve the multi-strategy routing in the WSN.As a case, we present the Potential Based Real-Time Routing(PRTR) protocol, which minimizes the end-to-end delay of real-time packets and effectively alleviates the congestion for throughput improvement simultaneously.; 国家自然科学基金课题(60971102、60773138) |
