Proposal and Evaluation of a Selection Method of Relay Nodes for Wireless Flooding by Exchanging Neighbor Node Information

摘要

Resulting from the wide spread of ad hoc networks, it becomes important to establish the routing mechanism in a dense ad hoc network where there are a number of nodes in the radio propagation area of a specific node. Here, a number of nodes will respond to a control message such as route request from the specific node, and therefore, the number of re-broadcasted messages will increase. In this paper, we propose a method for decreasing this number of re-broadcasted messages in wireless flooding. This method relies on the Hello message exchange with the information of neighbor nodes. Based on this information, it selects relay nodes which resides at the boundary of radio propagation area. This paper also shows the results of evaluation.
