Abstract:

 To deal with the safety weakness in resisting active attacks from malicious nodes, trust metric is introduced to combat the attacks by loading a trust model on the proposed distance-based location-aided routing (DBLAR). The improved routing algorithm ST-LAR uses direct trust and recommendation trust to prevent malicious nodes with low trust value from joining the forwarding. Simulation results show that STLAR
can effectively resist attacks from malicious nodes. Its performance is also better than DBLAR in terms of average end-to-end delay, packet successful delivery ratio and throughput.
