Environment-Aware Trusted Data Delivery in Multipath Wireless Protocols

Current multipath protocols for Multi-Hop Wireless Networks (MWNs) use hop-count as the default route selection criteria. Route selection should also consider network and link conditions. We propose a networkenvironment-aware trust-based route selection framework for MWNs that makes informed and adaptive route-selection decisions. A node quantifies trust values for its neighboring nodes and for the routes that pass through it. The trust metric adjusts to varying network conditions and quick convergence of the protocol implies it works well in mobility scenarios. Glomosim simulations demonstrate throughput improvement over conventional multipath protocols under congestion, link failure and route unreliability scenarios.
