Abstract
The characteristics of mobile Ad Hoc network make it face much more security threats than wired network, while the security of routing is the premise of secure application of Ad Hoc networks. In allusion to the safety weakness of resisting the active attacks from malicious nodes, trust metric is introduced to defend those attacks by loading a trust model on proposed Distance-Based LAR (DBALR). The improved Secure Trust-based Location- Aided Routing (ST-LAR) algorithm utilizes direct trust and recommendation trust to prevent malicious nodes with low trust value from joining the forwarding. Simulation results reveal that ST-LAR can resist attacks from malicious nodes effectively; furthermore, it also performs better than DBLAR in terms of average end-to-end delay, packet successful delivery ratio and throughput.
