Wireless Sensor Network in IoT and Performance Optimization

Abstract

: A serious problem in Wireless Sensor Networks (WSNs) is to attain high-energy efficiency as battery is used to power and have limited stored energy. They can’t be suitably replaced or recharged. Appearance of renewable energy harvesting techniques and their combination with sensor devices gives Energy Harvesting Wireless Sensor Networks (EHWSNs). IoT is now becoming part of our lives, comforting simplifying our routines and work life. IoT is very popular . It connects together, computes, communicates and performs the required task. IoT is actually a network of physical devices or things that can interact with each other to share information. This paper gives an overview of WSN and IoT, related work, different ways of connecting WSN with internet, development of smart home, challenges for WSN etc. Next a Framework for performance optimization in IoT is given and QC-PC-MCSC heuristic is analyzed in terms of Energy Efficiency and Life Time of a sensor on Energy Latency Density Design Space, a topology management application that is power efficient. QC-PC-MCSC and QC-MCSC are compared for Energy Efficiency and Life Time of a sensor over energy latency density design space, a topology management application.

Interleaved Honeypot-Framing Model with Secure MAC Policies for Wireless Sensor Networks

“…Similarly, the recent advances and security requirements for WSNs and IoT were discussed by Gupta et al [ 22 ] and Bharany et al [ 23 ]. The crucial contributions of the existing techniques were found in the analysis of performance improvement, energy optimization solutions, security benefits, cyberspace investigations, machine learning frameworks, and blockchain-based distributed solutions.…”

“…The crucial contributions of the existing techniques were found in the analysis of performance improvement, energy optimization solutions, security benefits, cyberspace investigations, machine learning frameworks, and blockchain-based distributed solutions. As IoT and WSN participants are mostly deployed under a distributed environment, the detailed analysis on the real-time technical issues of Gupta et al [ 22 ] and Bharany et al [ 23 ] provided notable information. Xiao et al [ 24 ] developed MAC security and computation analysis models for IEEE 802.15.4 WSNs.…”

“…A ativação sob demanda [6] é um mecanismo baseado na ideia de um rádio despertador, que é um rádio de baixa potência que escuta um sinal de despertar e envia uma mensagem para a CPU que, por sua vez, ativa o rádio primário.…”

Wireless sensor networks in the internet of things: review, techniques, challenges, and future directions

“…Disadvantages: The flat network structure has problems in the organization of nodes, route establishment, control and maintenance of message overhead, which can take up a lot of bandwidth and affect the transmission rate of network data; in addition, the whole system will lose a lot of energy on a macro level; and poor scalability. -Hierarchical network structure: the network is divided into two parts: the upper layer is a sub-network structure created by connecting the primary backbone nodes, the bottom layer is a sub-network structure created by connecting generic sensor nodes [50]. Advantages: in the hierarchical structure, the sensor network is divided into multiple clusters, each cluster is made up of a cluster head and several cluster members; the cluster heads comprise the network's upper level; It is the responsibility of cluster head nodes to transmit data across clusters, cluster members are only responsible for the collection of data, this significantly decreases the network's amount of control information, with good scalability [50].…”

Disadvantages: problematic is the cluster head's high energy consumption, as the frequency of sending and receiving messages is several times or more than ten times higher than that of a normal node, thus requiring that the cluster head can be replaced by running a cluster head selection procedure within the cluster.…”
