Sliding window-based network coding with cooperative communication in wireless networks
Wanyi Feng, Hongwei Luo, Baolin Sun, Chao Gui · 2017
Multiuser cooperative communication is a new communication paradigm that allows multiple source node transceivers data to destination node. Network coding (NC) has been proved to provide significant performance improvement for cooperative communication in wireless networks (WNs). Sliding window-based network coding is a variation of NC that is an addition to data streaming and improves the data delay on WSs. In this paper, we propose a Sliding Window-based Network Coding with Cooperative Communication in wireless networks (SW-NCCC). SW-NCCC preserves the degree distribution of the encoded packets through the recombination at the nodes. SW-NCCC enables to control the decoding complexity of each network coding independently from the packets received and recover the original data. The performance of the SW-NCCC is studied using NS2 and evaluated in terms of the throughput, encoding overhead when a data packet is transmitted. The simulations result shows that the SW-NCCC with our proposition can significantly improve the wireless network throughput and achieves higher diversity order.
