| Abstract & Background | The ad hoc network is a temporary wireless system without a fixed infrastructure. Many routing algorithms have been proposed. This network routing should be scalable and effective because network topology changes dynamically and bandwidth is limited. Cluster-based algorithms are among the most effective and scalable methods. However, it can not handle dense situations efficiently. To reduce redundant rebroadcasts to alleviate this problem, this paper proposes a probability theorem that there is a hidden gateway in a dense network scenario. Then it presents a distributed gateway selection algorithm and proves its correctness. Simulations results show that the method can efficiently save rebroadcast rate of packet to transmit and broadcast latency time in the case of guaranteeing broadcast success rate.
