Abstract—In wireless ad hoc networks, the node communicates with each other directly by message broadcasting. Since there is no pre-defined infrastructure, the messages flooded by broadcasting may cause a serious broadcast storm problem. To improve broadcast efficiency, we propose node-stamping approaches that introduce the stamp list to track up-to-date visited nodes and their neighbors to prune more redundant-messages. In addition, we develop stamp reduction and compression techniques to reduce the cost of node stamping. Compared with previous methods, the simulation results show that the node-stamping approaches improve broadcast efficiency further with reasonable stamp cost.
Index Terms—Ad hoc networks, broadcast storm, identity stamping, and path tracking.
