The paper deals with the packet scheduling of voice traffic of IEEE 802.16e under femto cellular network where the length of wireless link is few meters. Instead of distribution of MCS (Modulation and Coding Scheme) levels of previous literature, only availability of traffic channel is considered in packet scheduling since the short wireless link of femto(More)
Applications in modern data centers have a wide variety of resource requirements along the four main dimensions of computing, memory, storage, and networking. Data centers must manage these resources separately for each dimension, resulting in highly inefficient allocation of precious resources or even disastrous schemes that contribute to low utilization(More)
Both the use of very large arrays of antennas and flexible time division duplexing (TDD) designs have become prominent features of next generation 5G cellular systems. However, both enabling technologies suffer from severe interference effects, respectively known as pilot contamination and base-station-to- base-station (B2B) interference. In this paper, a(More)

LTE-A based system used fixed relays which are not suitable for wireless network. In wireless network terminal relays is most beneficial scheme but it is typically battery operated with limited processing and transmission capabilities. To reduce energy consumption an energy efficient cooperative medium access control protocol has been used which maximize(More)
