Rateless Coding-based Cooperative Transmission/Routing for Wireless Networks
Prof. Lingjia Liu, Associate Professor, Wireless@VT, Department of ECE, Virginia Tech delivers talk on rateless coding based cooperative transmission.
Abstract: Cooperation among the nodes of wireless networks can increase communication reliability, reduce energy consumption, and decrease latency. The possible improvements are even more significant when nodes perform mutual-information accumulation, e.g., by using rateless codes. In this talk, we investigate communication problems in such networks. That is, we investigate how advanced physical (PHY) layer coding techniques (e.g. rateless coding) would impact various network layers of a wireless network (e.g., resource allocation and routing strategies). Rateless coding-based cooperative communication for 1D line network, 2D grid network, 2D random network, and dynamic spectrum access network will be presented and hardware demo using USRP N210s will be discussed. All these findings suggest that rateless coding-based cooperative routing can significantly improve network performance in an efficient and robust way.
