Abstract |
: |
The technology revolution in wireless communications and micro-electro-mechanical systems (MEMS) has a direct impact on wireless sensor network (WSN) development. WSNs collect and process data from an area of interest. WSNs can be used for several application areas, such as the military, home, or environment. These devices typically have limited computing power and are designed to operate on batteries. Consequently, routing protocols that are applied to other networks cannot be used for WSNs. Many routing protocols for WSNs have been proposed, but none has made security a goal. This makes them easy targets for attacks. It is important to apply some level of security, so that WSNs are difficult to attack, especially when they are used in critical applications. One of the best categories of routing networks in WSNs is hierarchical protocols (cluster-based), where sensor nodes divided into small groups are an effective technique to achieve power savings, scalability, and routing. One of the well-known protocols in this category is the Low Energy Adaptive Clustering Hierarchy (LEACH). However, LEACH is vulnerable to many attacks. A LEACH protocol that achieves the desired security goals while keeping an acceptable level of energy consumption is a challenging task in WSN. The Enhancing Secure LEACH Protocol (MS-LEACH) is a modified version of LEACH with cryptographic protection against outsider attacks. MS-LEACH enhances security in LEACH but increases power consumption. To counter the power consumption in secure LEACH protocols, while keeping an acceptable level of security, we propose Secure Lightweight LEACH (SLW-LEACH). The simulation results of the proposed SLW-LEACH outperform MS-LEACH protocols, in terms of energy consumption, network lifetime, network throughput, and normalized routing load. |
