Evaluation of Energy Consumption using Receiver–Centric MAC Protocol in Wireless Sensor Networks

Abstract

At present day's wireless sensor networks, obtain a lot consideration to researchers. Maximum number of sensor nodes are scattered that can communicate with all others. Reliable data communication and energy consumption are the mainly significant parameters that are required in wireless sensor networks. Many of MAC protocols have been planned to improve the efficiency more by enhancing the throughput and energy consumption. The majority of the presented medium access control protocols to only make available, reliable data delivery or energy efficiency does not offer together at the same time. In this research work the author proposes a novel approach based on Receiver Centric-MAC is implemented using NS2 simulator. Here, the author focuses on the following parametric measures like -energy consumption, reliability and bandwidth. RC-MAC provides high bandwidth without decreasing energy efficiency. The results show that 0.12% of less energy consumption, reliability improved by 20.86% and bandwidth increased by 27.32% of RC-MAC compared with MAC IEEE 802.11.

Downlink massive full dimension-multiple input multiple output downlink beamforming analysis at 3.5 GHz using coordinated ON-OFF switching

“…Similarly, the column element is in charge of elevation beamforming, which involves adjusting the angular direction based on the UE's location. The linearly polarized antenna array is appropriate for generating multiple beams with respect to different UEs distributed within the macro cell [29]. In this study, focus on minimum number of active antenna elements selection on different antenna array sizes includes 16×16, 32×32, 64×64 and 128×128 to achieve a reasonable data rate using conjugate beamforming with optimistic power allocation to respective UEs for beamforming from BS [30].…”
