The Nash Bargaining Solution (NBS) has been broadly suggested as an effective solution for the problem of fair allocation of multiple resources, namely bandwidth allocation in datacenters. In spite of being thoroughly studied, and provably strategy-proof for most scenarios, NBS-based allocation methods lack research on the strategic behavior of tenants in the case of proportionality of resource demands, which is common in datacenter workloads. We found that misbehavior is beneficial: by lying about bandwidth demands tenants can improve their allocations. We show that a sequence of selfish improvements leads to trivial demand vectors for all tenants. It essentially removes sharing incentives which are very important for datacenter networks. In this paper, we analytically prove that tenants can misbehave in 2- and 3- tenants cases. We show that misbehavior is possible in one recently proposed NBS-based allocation system if proportionality of demands is taken into account. Monte Carlo simulations were done for 2–15 tenants to show a misbehavior possibility and its impact on aggregated bandwidth. We propose to use another game-theoretic approach, namely Dominant Resource Fairness (DRF) to allocate bandwidth in the case of proportional demands. We show that this method performs significantly better than NBS after misbehavior.

Train-to-ground communication system as an important part of the train control system , its performance is essential to guarantee the high safety and efficiency of train operation. However, due to the disturbances caused by movement speed of trains ,terrains, and other environmental interferences ,the existing communication system is often unable to provide a high speed link that is stable enough. Therefore, a reasonable bandwidth allocation strategy is necessary to solve the discrepancy between the demanding data rates and the insufficient bandwidth. This paper propose a bandwidth allocation strategy based on 0-1 knapsack problem and Asymmetric Nash Bargaining Solution, which can effectively reflect different bargaining power of all kinds of services, and improve the reliability and security of the transmission system. Finally, we operate a network simulation by NS2. The simulation show that the proposed scheme can enhance the rate of resource utilization ,get small and stable communication delay and ensure reliable transmission of the high-priority services and the safe operation of the train.
