Abstract
Techniques are provided for allowing a node () in an ad hoc network to deterministically decide whether to relay broadcast information to another node in the ad hoc network. The node () receives broadcast information and measures received signal strength (RSS) of the broadcast information. The node () may determine if the measured RSS is below a low threshold, and if so, can relay the broadcast information to neighbor nodes. Otherwise, the node () can also determine if the measured RSS is above a high threshold, and if not, wait for a waiting period before relaying the broadcast information to the neighbor nodes. The node () may dynamically adjust the low threshold by decreasing the low threshold as the number of neighbor nodes increases and may dynamically adjust the high threshold by increasing the high threshold as the number of neighbor nodes decreases.
