This work presents a deterministic channel that rules according to inverse a power propagation law. The proposed channel model allows us to derive the lower bound and upper bound of packet's capture probability in Rayleigh fading and shadowing cellular mobile system. The problem of hidden terminals can be resolved by the establishment of a carrier sense(More)
Mutual funds become one of the major channels for investors because of professional management, and the advantage of enjoying profit and sharing risks. The goal of this study is applying Grey prediction, radial basis function neural network (RBFNN) and Grey-RBFNN to predict the net asset value (NAV) of single nation equity funds. Grey model is a simple(More)
This work presents a deterministic channel that rules according to inverse α power propagation law. The proposed channel model allows us to derive the lower bound and upper bound of packet's capture probability in Rayleigh fading and shadowing cellular mobile system. According to these capture probabilities, we analyze the system performance in the(More)
For multiple random accesses, a low throughput due to channel contention is the major limitation. The most latency occurs in the contention phase and, therefore, reducing the delay time thus becomes a relevant task. A collision occurs in real network access if two or more packets are simultaneously transmitted. Hence, the contention must be resolved when(More)
