Enhancing S-LEACH security for wireless sensor networks

Abstract

Abstract² Developing effective security solutions for wireless sensor networks (WSN) are not easy due to limited resources of WSNs and the hazardous nature of wireless medium. The implementation of encryption/decryption algorithms which are the most essential part of the secure communication can be very intricate in WSNs since they incorporate routines that having very complex and intense computing procedures. A secure clustering protocol that achieves the desired security goals while keeping an acceptable level of energy consumption is a challenging problem in wireless sensor network. LEACH (Low-Energy Adaptive Clustering Hierarchy) protocol is a basic clustering-based routing protocol for WSNs. S-LEACH is the first modified version of LEACH with cryptographic protection against outsider attacks. This paper proposes MS-LEACH to enhance the security of S-LEACH by providing data confidentiality and node to cluster head (CH) authentication using pairwise keys shared between CHs and their cluster members. The security analysis of proposed MS-LEACH shows that it has efficient security properties and achieves all WSN security goals compared to the existing secured solutions of LEACH protocol. A simulation based performance evaluation of MS-LEACH demonstrates the effectiveness of proposed MS-LEACH protocol and shows that the protocol achieves the desired security goals and outperforms other protocols in terms of energy consumption, network lifetime, network throughput and normalized routing load.

An Efficient Distance-Energy-based Minimum Spanning Tree (DE-MST) for Wireless Sensor Networks

“…It incorporates data fusion into the routing protocols to reduce the amount of information to be transferred to the (BS). Modified LEACH has been proposed in previous studies [9][10][11][12][13][14]. Farooq-et al, [10] proposed a Multi-hop Routing LEACH (MR-LEACH) protocol that divides the network into various cluster layers, wherein every cluster collaborates with BS to conserve energy.…”

“…Simulation result shows that M-LEACH performs effectively in prolonging the network life_time and improves the data transmission efficiency. ElSaadawy and Shaaban [14] proposed Modified S-LEACH (MS-LEACH) to enhance the security of the existing LEACH. This technique includes data confidentiality between node and cluster head using pair wise keys shared between CHs and their cluster members.…”

LS-LEACH: A New Secure and Energy Efficient Routing Protocol for Wireless Sensor Networks

“…On the other hand, the other proposed protocols based on LEACH tried to only add overhead cost on the network without trying to save the network energy which reduced the network life time [4,7,20]. Furthermore, we used CBC MAC with 4 bytes (2 32 ) which is a reasonable authentication protocol as the sensor wouldn't stand a bruteforce attack with 2 32 attempts.…”

“…However, assuring data confidentiality, authenticity, availability, and integrity must be maintained. Security is one of the challenging aspects in wireless networks because it has effect on the sensors resource due to the very limited resources in the wireless sensors [3,4]. Mobile and ad-hoc networks employ conventional security.…”

ICHALEC Improved Cluster Head And Low Energy Consumption Protocol In Wireless Sensor Network

“…When the last node completes its transmission then the schedule is repeated. Leach is a cluster based protocol in which cluster head rotates randomly to evenly distribute the energy among the nodes in the network [14]. Leach protocol works in various rounds.…”
