Abstract:

In order to solve the problem that the node selection algorithm in marine heterogeneous wireless network is not effective in real time and does not match well with mobile nodes, a network access selection algorithm based on dynamic analytic hierarchy process (DAHP) and synergetic principle is proposed. On the basis of satisfying multi factor decision and static node network selection, this algorithm uses the DAHP method to determine the subjective weight of the access decision index, uses the synergetic correlation principle to determine the objective weight, and uses received power to determine the location weight of mobile nodes. By redistributing the subjective, objective, and location weights, it takes into account the real-time network state and task communication needs around mobile nodes. The algorithm improves the real-time performance and the matching with mobile nodes. The simulation results show that compared with the traditional network selection algorithm based on AHP and the synergetics principle and the mobile node algorithm based on distance, this algorithm reduces the traffic blocking rate of nodes and improves the communication smoothness and real-time performance.

Key words: dynamic analytic hierarchy process (DAHP), synergetic principle, mobile node, network access selection
