A Trustworthiness-Based Ad-Hoc Routing Protocol in Wireless Networks

Wireless ad-hoc networks which do not use network infrastructure are getting more important in various types of applications like vehicle-to-vehicle (V2V) networks. Here, neighbor nodes with which each node can directly communicate may be changed, e.g. due to movement of nodes and faults of networks and nodes. Messages are forwarded to destination nodes by wireless node-to-node communication in ad-hoc routing protocols. In this paper, we newly propose a reliable one-to-one communication protocol named TBAH (Trustworthiness-Based Ad-Hoc communication) protocol where a route to the destination node is dynamically found by selecting trustworthiness nodes. In this paper, the trustworthiness of a node is defined in terms of electric energy consumption of the node. We show the total electric energy consumption can be reduced in the TBAH protocol compared with the AODV protocol in the evaluation.
