| Abstract: |
| This paper surveys the state-of-the-art researches of wireless cooperative relaying networks with network coding, investigates representative resource allocation strategies, and analyzes their features, performance and system requirements. It then discusses the effects of network coding, including digital network coding and physical network coding, in the design of resource allocation strategies for wireless cooperative relaying networks. As a result, a pragmatic system-level cross-layer optimization framework and associated core design principles are suggested. Finally, the future work of resource allocation for wireless cooperative relaying networks is presented, and some essential problems to be solved for final practical proposals are also addressed. |
| Key words: wireless cooperative relaying network resource allocation network coding cross-layer practicality |
