一种编码感知路由低时延数据传输算法
Low-delay data transmission algorithm for coding-aware routing
摘要
Abstract
It is significant to reduce packet delivery delay for real‐time applications in a wireless network . Existing coding aware routing algorithms use the opportunistic coding scheme in the packet coding algorithm . They never delay packets to wait for the arrival of a future coding opportunity which results in the degradation of the contribution of network coding to delay performance . To overcome the above problem , for coding‐aware routing , this paper presents a low‐delay data transmission algorithm based buffer management . In the coding node , this algorithm decides packets according to the queue‐length based threshold policy instead of the regular opportunistic coding policy as used in existing coding‐aware routing algorithms . This algorithm introduces the network delay training phase before the data transmission phase to make the coding node obtain the optimal threshold for the queue‐length based threshold policy . Simulation results show that our algorithm can achieve a lower packet delivery delay , a lower packet loss ratio and a higher throughput than the traditional opportunistic coding policy in network congestion .关键词
