چکیده
Device-to-device communication offers a promising technology for the 5G network that aims to enhance data rate, reduce latency and cost, improve energy efficiency, provide other desired features. The heterogeneous (5GHN) with decoupled association strategy of downlink (DL) uplink (UL) is solution challenges faced in 4G (4GHN). research presented this paper evaluates performance 4GHN as well DL-and-UL-coupled (DU-CP) access scheme comparison 5GHN DL-and-UL-decoupled (DU-DCP) terms efficiency throughput four-tier networks. are optimized both scenarios, i.e., DU-CP DU-DCP, results compared. Detailed analyses DU-DCP schemes were conducted help comparisons achieved by implementing genetic algorithm (GA) particle swarm optimization (PSO). Both these algorithms suited non-linear problem under investigation which search space large. simulation have shown gives better than efficiency. PSO achieves an 12 Mbits/joule 42 whereas GA yields 28 55 DU-DCP. proposed method compared those three schemes. show using outperforms methods.

15 صفحه اولEnergy Efficiency and Throughput Optimization of Cognitive Relay Networks
In this paper, we investigate the energy efficiency and throughput optimization problem of cognitive relay networks. We propose to design sensing time and signal to noise ratio (SNR) to maximize the energy efficiency and throughput, since analytical and empirical studies have shown that sensing time and SNR are key factors for energy efficiency and throughput. We design a method that simultaneo...

In this paper, we investigate the coverage performance and energy efficiency of multi-tier heterogeneous cellular networks (HetNets) which are composed of macrocells and different types of small cells, i.e., picocells and femtocells. By virtue of stochastic geometry tools, we model the multi-tier HetNets based on a Poisson point process (PPP) and analyze the Signal to Interference Ratio (SIR) v...

Improving Energy Efficiency and Throughput in Heterogeneous Mobile Ad Hoc Networks
The nodes are expected to transmit at different power levels in heterogeneous mobile adhoc networks, thus leading to communication links of different length. Conventional MAC protocols that unconditionally presume that links are bi-directional and with unvarying energy distribution may not succeed or execute badly under such circumstances. Interference and signal loss resulting out of distance ...
