It's necessary to enhance the capacity of wireless access network to provide mobile IPTV service. In this paper MMR(Mobile Multi-hop Relay) system is introduced to increase the performance of mobile system based on IEEE 802.16m which introduced network coding technology to increase the performance of radio link. Radio link quality and mobile terminal throughput are analysed by simulation when RS(Relay...
In this paper, a novel observe-and-forward (OF) cooperative scheme is proposed for relay-enhanced wireless cooperative systems. In this scheme, the codewords transmitted from the source are regenerated by the decoder at the relay and forwarded without re-encoding or interleaving. The decoding processes for different streams of a transmitted codeword can be parallel, which greatly reduces the relaying...
In this paper, a distributed mobile relay power control (DMRPC) scheme for maximizing individual cell throughput is proposed for mobile relay station (MRS) aided system. In the system with DMRPC, the power levels of MRSs are controlled by individual cell without cell cooperation and signaling overhead, and the appropriate power levels of MRSs are selected to maximize the cell throughput of their individual...
Routing between a base station and a mobile station is one of the key issues that should be addressed in multi-hop cellular systems. It should also take into account maximization of the radio resource utilization of the entire system, in which the radio resource of each cell must be shared by the base station and relay stations. In this paper, we propose a joint bandwidth allocation and routing scheme...
To enhance coverage and throughput of IEEE 802.16 networks, 802.16j task group has standardized capabilities and functionalities of multi-hop relay (MR). This paper first mentions simulation assumptions based on the draft of IEEE 802.16j. We present three relay station (RS) deployment scenarios of throughput enhancement, coverage extension and mobile relay. This paper takes WiBro as an example of...
