A Network Coding-Aware Routing Mechanism for Time-Sensitive Data Delivery in Multi-Hop Wireless Networks

다국어 초록 (Multilingual Abstract)

The network coding mechanism has attracted much attention because of its advantage of enhanced networkthroughput which is a desirable characteristic especially in a multi-hop wireless network with limited linkcapacity such as the device-to-device (D2D) communication network of 5G. COPE proposes to use the XORbasednetwork coding in the two-hop wireless network topology. For multi-hop wireless networks, theDistributed Coding-Aware Routing (DCAR) mechanism was proposed, in which the coding conditions for twoflows intersecting at an intermediate node are defined and the routing metric to improve the codingopportunity by preferring those routes with longer queues is designed. Because the routes with longer queuesmay increase the delay, DCAR is inefficient in delivering real-time multimedia traffic flows. In this paper, wepropose a network coding-aware routing protocol for multi-hop wireless networks that enhances DCAR byconsidering traffic load distribution and link quality. From this, we can achieve higher network throughput andlower end-to-end delay at the same time for the proper delivery of time-sensitive data flow. The Qualnet-basedsimulation results show that our proposed scheme outperforms DCAR in terms of throughput and delay.
