A Novel Hybrid Trust Management Framework for MANETs

Mobile ad hoc network (MANET) is a promising network paradigm for the future networking. To secure a MANET, we focus on trust management framework, which is intended to cope with misbehavior problem of nodes and stimulate nodes to cooperate with each other. However, there are still many intrinsic problems with the existing trust management frameworks, which remain unsolved, such as frangibility under possible attacks. To design a robust trust management framework, we investigate these intrinsic problems with the existing frameworks, and propose a hybrid trust management framework (HTMF) to construct trust environment for MANETs in the paper. Performance evaluations also have been performed, which show that the proposed HTMF is more robust and reliable than the existing frameworks.
