Abstract
The marine Internet technology has been proposed to exploit abundant communication and network resources available in the ocean in order to provide more cost‐effective and handy network services therein. Basically, the marine Internet architecture is based on heterogeneous large‐scale dynamic wireless, which consists of different types of networks such as satellite networks, coastline networks, and ship ad‐hoc networks etc. These networks are different in terms of networking cost, capacity, and performance as well as availability and reliability. This imposes challenges for network selection, especially when there is no guarantee on the availability and reliability of network resources in oceans, which is different from network selection in terrestrial environments. Thus, this paper studies a network selection scheme by jointly considering the above uncertainty of network resources based on the analytic hierarchy process (AHP) for marine Internet. The proposed scheme is evaluated through a simulation study on the EXata platform, in comparison with the Simple Additive Weighting and the Multiplicative Exponent Weighting schemes. The simulation results show that the proposed scheme yield better performance.

How to select the target network in the marine Internet where multiple access networks coexist? The general idea of solving such problems is to propose a mathematical algorithm to assign weights to each index and to calculate the comprehensive utility value of each index corresponding to the candidate network through the utility function
analytic hierarchy process (AHP)’s throughput per unit time is always the highest. This is because AHP chooses the ad hoc network and coastline networks, which have a higher throughput than the satellite one, which is selected by Simple Additive Weighting (SAW) and Multiplicative Exponent Weighting (MEW)
Summary
There are abundant resources in the ocean. Many countries, especially major powers, have made a huge investment on the ocean, and it is necessary to develop marine Internet technology. The common algorithms for setting weights are Simple Additive Weighting (SAW) [2], Multiplicative Exponent Weighting (MEW) [3, 4], and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) [5,6,7]. In the marine Internet scene, users are sparsely distributed mainly on ships, users are unevenly distributed, and different users have different preferences This imposes challenges for network selection, especially when there is no guarantee on the availability and reliability of network resources in oceans, which is different from network selection in terrestrial environments. This paper proposed an algorithm based on the analytic hierarchy process (AHP) [4, 5] to select the target network
