Advancing Wireless Sensor Networks Through Intelligent Multi-Hop Routing and Fuzzy Decision-Making for Cluster Head Selection

Problem Definition

The literature review highlights various drawbacks and limitations of conventional routing protocols, particularly the popular LEACH model, in wireless sensor networks. One of the key issues observed is the high energy consumption resulting from cluster heads needing to travel greater distances, leading to a shorter network lifespan. Additionally, the selection of cluster heads using fuzzy inference systems only considers limited parameters, neglecting other factors that can impact network performance. Moreover, the direct communication of non-cluster nodes with the base station further exacerbates energy usage. These shortcomings underscore the urgent need to enhance existing protocols to improve network efficiency, stability, and longevity.

By addressing these flaws, it is possible to optimize energy utilization and prolong the overall lifespan of wireless sensor networks.

Objective

The objective of the project is to design an energy-efficient protocol for Wireless Sensor Networks (WSNs) that addresses the shortcomings of conventional routing protocols, such as the popular LEACH model. The project aims to improve network efficiency, stability, and longevity by implementing a multi-hop routing approach within each cluster to reduce energy consumption. Additionally, the project will focus on enhancing the cluster head selection process using an extended fuzzy logic input parameter and a fuzzy decision model considering key parameters of sensor nodes. By implementing a relay mechanism for data transmission from sensor nodes to the base station via neighboring nodes and cluster heads, the project seeks to minimize energy usage and optimize the overall lifespan of WSNs.

Proposed Work

In this project, we have identified a gap in the existing literature regarding the inefficiencies of conventional routing protocols in Wireless Sensor Networks (WSNs). The current protocols, such as the LEACH model, suffer from high energy consumption due to the selection of cluster heads and direct communication with the base station. To address this issue, the objective of our project is to design an energy-efficient protocol based on an extended fuzzy logic input parameter for cluster head selection in WSNs. Our proposed work involves implementing a multi-hop routing approach within each cluster to reduce the distance that cluster heads need to travel, thus conserving energy and extending the network lifespan. Additionally, a fuzzy decision model considering key parameters of sensor nodes will be used for effective cluster head selection.

By implementing a relay mechanism for data transmission from sensor nodes to the base station via neighboring nodes and cluster heads, energy consumption will be minimized, leading to a more stable and efficient network. Our rationale for choosing these techniques lies in their ability to address the drawbacks of existing protocols and improve the overall performance of WSNs in terms of energy efficiency and network lifespan.

Algorithms Used

Fuzzy Logic is used in the proposed work to enhance the communication efficiency in cluster-based wireless sensor networks. The algorithm helps in selecting the cluster head (CH) based on four important parameters of sensor nodes: average distance of neighbor node, residual energy, moving speed, and pause time. By using fuzzy decision model, the CH selection process is optimized, leading to improved network performance and energy conservation. Additionally, the proposed approach implements multi-hop routing within each cluster, where sensor nodes communicate with each other over shorter distances before sending data to the base station. This minimizes the energy consumption of CH nodes and extends the network lifespan by reducing the distance traveled for data transmission.

Moreover, a mechanism is introduced to relay data from sensor nodes outside the cluster to the CH, further minimizing energy consumption and enhancing network efficiency.
