Abstract
Private-Internet of Things (P-IoT) is IoT network with for private users using dedicated frequencies. Ad hoc mode is the main operation mode of P-IoT. Since Ad hoc mode of P-IoT is a narrowband network, the congestion is the fatal problem on the intermediate nodes. Topology control is an effective way to reduce congestion. A topology control algorithm based on node degree for P-IoT is proposed in this paper. The topology control algorithm minimizes the node degree of the communicating nodes under the premise of guaranteeing network connectivity and constructs a network topology with less sparsity. The simulation results show that our algorithm can markedly reduce the average node degree and the sparsity of topology without decline of the network connectivity.
