Cooperative Communications in Machine to Machine (M2M): Solutions, Challenges and Future Work

摘要: The application of cooperative communication (CC) in wireless networks makes it possible for the terminals to hear and aid transfer each other’s information required destinations. CC utilizes advantage broadcast nature communications achieve its objectives. advantages enjoyed by that employ principles include: improvement connectivity, energy utilization, spectrum efficiency, counteracting limited per device complexity, a boost reliability among devices network. When is compared with other techniques perform functions similar like multiple input output, has an upper hand due fact hardware feasible deployment more flexible. implementation machine (M2M) this paper based on use relays clustering protocols. Popular protocols are presented as solutions, detailed emerging research challenges include but not to: escalating complex scheduling design, increased message overheads, intra inter network interferences, end-to-end latency, redundancy discussed. Future works includes critical full duplex relays, utilization non-regenerative mode relay operation, cross layer optimization, scheme reconciling quality-of-service properties, designing hybrid proposed. They aimed at improving hence foster efficiency M2M resources.
