Most of the existing routing protocols for heterogeneous multi-hop wireless networks use the on-demand routing protocols owing to its suitability for dynamic topology environments, but it will easily lead to a waste of network resources because of the large number of data packets being broadcast. What’s more, some nodes of heterogeneous multi-hop wireless networks may be malicious nodes or selfish nodes which can easily lead to a link attack, so the routing security issues are also important for heterogeneous multi-hop wireless networks. Thus, how to build a secure routing protocol with a lower overhead for heterogeneous multi-hop wireless networks is a challenge. This paper propose a novel routing protocol called TSRAL for heterogeneous multi-hop wireless networks, which combines the location information of nodes and trust value to select the next forwarding node. Simulation results show that TSRAL can reduce the number of data packets being broadcast and the number of hops during routing and it can also ensure the safety of the route.
