Secure Lightweight Routing Scheme for Energy Efficient Wireless Sensor Networks

Abstract

The technology revolution in wireless communications and micro-electro-mechanical systems (MEMS) directly affects the development of wireless sensor networks (WSNs), which are used in several application areas, including the military, home, and environment. One of the best categories of routing networks in WSNs are hierarchical protocols (cluster-based). The wellknown protocols in this category include the Low Energy Adaptive Clustering Hierarchy (LEACH). However, the LEACH is vulnerable to many attacks. To provide cryptographic protection against outsider attacks, a modified version of LEACH, called Enhancing Secure LEACH (MS-LEACH) protocol, is used. MS-LEACH enhances security but increases power consumption. To maintain an acceptable level of security and decrease the power consumption of secure LEACH protocols, the present research proposes a Secure Lightweight LEACH (SLWLEACH) scheme. The simulation results show that this proposed SLW-LEACH protocol outperforms the MS-LEACH in terms of ne

A New Approach for Cluster Head Selection in Wireless Sensor Networks

“…Cognitive radio-inspired LEACH (CR-LEACH) enhances spectrum utilization and reduces interference through dynamic frequency and channel adaptation [23]. Furthermore, Secure LEACH (S-LEACH) enhances network security by utilizing cryptographic techniques and secure authentication methods [24,25]. LEACH for mobile sensor networks (LEACH-MSN) incorporates mobility-aware clustering mechanisms to accommodate dynamic node movement, ensuring efficient data collection and network connectivity [26].…”
