Implementation of energy-efficient cooperative communication for multi-hop WSN

Abstract

Wireless sensor network is a diverse network. One of the important limitation of the wireless sensor network is limited life-time, wireless nodes typically operates with small batteries for which replacement, when possible, is very difficult and expensive. Therefore nodes must operate without battery replacement for long time. Consequently, minimizing the energy consumption is a very important design consideration and energyefficient transmission schemes must be used for the data transfer in wireless sensor networks.This paper, proposes the energy efficient transmission scheme to minimize the per node energy consumption. In the proposed scheme after the cluster formation in the network potential cluster head will select the cooperative node to transfer data from one cluster to other. The results shows that by transmitting and/or receiving information jointly, tremendous energy saving is possible for larger transmission distances,even after considering the local energy cost necessary for joint information transmission and reception.

Multi‐hoped cooperative communication‐based wireless underground sensor network design

“…The WSN is hampered by a high level of human interference and knowledge delays. 11 WUSNs, which coordinate in the soil, are distinct from on the ground WSNs, according to Yu et al 12 WUSN systems are installed underground and do not need any network connection. Sensors, storage, a processor, a transmitter, an aerial, and a source of energy are all included in every package.…”

“…Agriculture is one of them, and WSN can help with the processing and impact on water supplies for irrigated agriculture and other purposes. The WSN is hampered by a high level of human interference and knowledge delays 11 . WUSNs, which coordinate in the soil, are distinct from on the ground WSNs, according to Yu et al 12 WUSN systems are installed underground and do not need any network connection.…”

A Cooperative Phase-Steering Technique with On-Off Power Control for Spectrum Sharing-Based Wireless Sensor Networks

“…Since R is the required data rate of the entire system, it can be regarded as the transmit rate at which the SS node intended to transmit. Therefore, the effective throughput in (18) represents the average transmit rate when the SS node tries to transmit data with transmit rate R.…”

“…Meanwhile, cooperative communications with multiple relay nodes can collaborate to form virtual antenna arrays to achieve spatial diversity [16]. If WSNs exploit a cooperative communication system, they can achieve cooperative diversity among the nodes distributed in the network so as to achieve better energy efficiency by distributing the transmit energy consumption burden to multiple nodes [17,18]. A cooperative communication system can reduce the required transmission power under a certain throughput requirement due to spatial diversity.…”

ANALISA PERBANDINGAN ROUTING PROTOKOL PADA WIRELESS SENSOR NETWORKS (WSNs)

“…Maka routing protokol sangat dibutuhkan sehingga proses pengiriman data memiliki jalur yang optimal [1], [3]. Dalam menentukan routing protokol yang digunakan, beberapa hal harus diperhatikan agar tidak terjadi kesalahan dalam pemilihan protokol [4], [5] Berdasarkan hasil dapat dilihat bahwa routing protokol SPIN memiliki delay yang lebih sedikit dibandingkan protokol lainnya. Untuk pengiriman data, perbedaan waktu ini tidak terlalu berdampak terhadap data yang diterima oleh node sumber.…”
