Energy Efficient Hardware and Improved Cluster-Tree Topology for Lifetime Prolongation in ZigBee Sensor Networks

Abstract

Abstract:In wireless sensor networks, building energy-efficient systems is one of the major challenges. In such networks, nodes are usually supplied by low power and small batteries. Many factors are involved in the energy consumption, and this issue may be considered as a cross-layer problem, from the hardware architecture to the application layer. This paper aims at presenting a hybrid solution for sensor networks based on two main aspects. The first one is the hardware architecture, where we present a prototype of a sensor node we designed. This node proved its efficiency in terms of energy consumption. The second aspect is related to the topology construction and presents a new topology control algorithm based on graph computing. Thus, our system consists of a real indoor application for temperature and humidity monitoring, applicable to home automation or industrial monitoring. We performed the experiments using a set of sensor nodes deployed over a building and proved the efficiency of the system in terms of energy consumption, network lifetime and data delivery.

Application research on piano teaching in colleges and universities based on remote wireless network communication

“…It is essentially a two-way wireless networking technology with a relatively low transmission rate. As a communication protocol, it can wirelessly network different digital devices so that they can communicate with each other and provide standardised instructions for the communication process [27]. To network through the ZigBee communication protocol, you can use the ZigBee protocol stack.…”

Adaptive Concepts and Optimization Approach to Design of Testbenches and Nodes for Wireless Sensor Networks

“…In wireless sensor networks, building energy-efficient systems is one of the major challenges. In such networks, nodes are usually supplied by low power and small batteries [30]. Also possible use copy-at-neighbouring-node retransmission strategy for improved wireless sensor network lifetime and reliability [31].…”

Efficient Resource Consumption by Dynamic Clustering and Optimized Routes in Wireless Sensor Networks

“…In the network environment, sensor nodes sense phenomenon then collect and process data and send to BS/sink in the end. One of the reasons of development and progression of the WSNs is using the inexpensive and affordable sensor nodes [3]. Therefore, WSNs are used in many applications such as civil, medical, military, governmental and probability-based applications as volcano [4].…”
