Abstract

Wireless sensor networks are relatively simple, scalable networks with many applications in the research field. They can provide benefits that a typical wireless network does not, such as ad-hoc distribution, lower costs, and higher flexibility. In a scenario where time is of the essence and dedicated base stations cannot be established, such as a storm or a volcanic eruption, mobile sinks must be used to gather data. We aim to introduce a fast cluster-based mechanism by which nodes can securely connect to one another based on trust and network clustering and begin transmitting data to a collection device while it is available. We also examine two possible attacks on a trust-based network, and present a heuristic solution for minimizing the negative effects of such an attack in an energy-efficient way. Through simulation, we show that this scheme performs better than others in terms of energy efficiency and network lifespan.
