On the Simulation of Communication Protocols with Multiple Mobile Nodes

In this paper, a high-performance routing protocol with multiple mobile nodes based on reliable active nodes is put forward since network nodes are not involved in the reliability work when the existing OSPF routing protocol forwards the packet, which results in several problems such as a low rate of packet forwarding, the long average delay of end-to-end, high energy consumption of network nodes and short service lifetime of nodes. The hierarchical model of active networks with multiple-mobile nodes was built, in which, reliable active nodes were divided into forwarding nodes and reliable nodes based on the functional requirements of this model, and consideration was given both to the efficiency and reliability of packet transmission. Besides, the energy consumption of network communication was calculated on the basis of this model and the packet transmission power was controlled. A high-performance routing protocol with multiple mobile nodes was designed to estimate the packet transmission delay time, calculate the forwarding moderate index of nodes, and select neighbor nodes in the active network. The simulation results show that this routing communication protocol effectively improves the packet forwarding rate, lowers the total energy consumption, shortens the average delay of end-to-end, and extends the service life of network nodes.
