SURVEY ON DELAY TOLERANT NETWORK USING PROVEST SCHEME

Abstract

Delay tolerant networks (DTNs) are typically encountered in military network environments wherever end-to-end property isn't secure because of frequent disconnection or delay[2]. This work prefer a provenance-based trust model, specifically PROVEST (PROVENANCE primarily based Trust model) that aims to attain correct end to end trust assessment and maximize the delivery of correct messages received by destination nodes whereas minimizing message delay and communication value underneath resource-constrained network environments. Provenance refers to the history of possession of a valued object or data. PROVEST use a data-driven approach to scale back resource utilization within the presence of egocentric or malicious nodes where as estimating a node’s trust dynamically in response to changes within the environmental and node conditions.
