Different from most the past routing algorithms only considering the shortest path first

or evaluating the trust level solely on the forwarding behavior

or depending on recommendation-based trust mechanism

we propose a novel subjective trust routing model under consideration to both communication reliability and path length.We introduce the concept of attribute similarity to inherently bind neighbor selection

trust evaluation

packet forwarding

and other routing processes.Based on the similarity degree

we put forward a new forwarding behavior.We give a recommended method to calculate the similarity degree between attributes.Simulations show that the routing scheme behaves better than Dynamic Source Routing (DSR) protocol and previous trust-based routing protocols on standing against the blackhole attack and the on-off attack

and meanwhile is not affected by the slander attack.
