Start year: 2013

Summary: LEACH (Low-Energy Adaptive Clustering Hierarchical) is a self-organizing, adaptive clustering protocol that uses randomization to distribute the energy load evenly among the sensors in the network. Like any protocol, LEACH is vulnerable to various threats. In Sybil attack, a malicious device illegitimately takes on multiple identities. Malicious device┬┐s additional identities are known as Sybil nodes. In this project, we will explore various forms of Sybil attacks and how to combat them by proposing various solutions based on simulation and also building a prototype with sensor nodes to validate our proposed scheme. In our proposed solution, we will detect malicious nodes (both fixed and mobile) based on various factors and prevent them from injecting malicious code and fabricated data into the clusters.
