Device-to-Device (D2D) communication has currently been emerging as a promising technology to increase capacity and to extend coverage area in cellular communication network. D2D communication allows direct communication between two or more devices such as mobile user equipments without any base station help as a relay. However, enabling D2D features in cellular communication network will reveal more...
Femtocell is a small cell of 10–30 meters radius deployed in the existing larger cell (macrocell) forming two-tier femtocell-macrocell cellular network. However, the deployment of femtocell into the existing macrocell cellular network is facing more complex interference problems. This paper focuses on interference management using power control methods for the uplink transmission of such two-tier...
Deployment of femtocell in macrocell cellular network which forms two-tier femtocell-macrocell cellular network faces more complicated interference problems, since it uses the same licensed frequency spectrum as its macrocell. This paper addresses the interference problems for downlink transmission in such two-tier cellular communication network. In this paper, interference management using power...
To achieve a reliable and robust system for environmental monitoring, there is an available technology that can be used to resolve this problem and moreover provide for better living. Wireless sensor networks (WSN) have been successfully applied in many environmental monitoring. An ad-hoc wireless sensor network consists of a number of small and self-power sensing devices (nodes) connected using effective...
Error control techniques are designed to ensure reliable data transfer over unreliable communication channels that are frequently subjected to channel errors. In this paper, the effect of applying a convolution code to the Scattered Random Network Coding (SRNC) scheme over a multi-hop wireless channel was studied. An interleaver was implemented for bit scattering in the SRNC with the purpose of dividing...
