Secure low energy adaptive clustering hierarchal based on internet of things for wireless sensor network (WSN): Survey

Internet of Things (IoT) allows different objects connect with each other through the Internet without any human's interaction. Wireless sensor network (WSN) is small sensor nodes that are densely deployed in places that are impossible to contain wired cables, it is considered as one of the IoT examples that focus on how sensors can monitor in several domains. The most WSN problems are focused on its battery power limitation that motivates the Hierarchical routing protocol to be used. Hierarchical routing protocol aims to reduce the usage of the network energy and to increase its lifetime. One of the most common Hierarchical routing protocols is the Low energy Adaptive Clustering Hierarchical routing protocol (LEACH) that deals with the security challenge. The security is one of the critical issues in WSN especially in the LEACH in term how to secure the content of the transmitted data and how to transmit these data in a secure manner to solve the attacks that it deals with, this survey focuses on how to secure LEACH using many methods that will also improve the LEACH itself.
