Cluster based trust proliferation and energy efficient data collection in unattended wireless sensor networks with mobile sinks
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.
