Self-configuration network model is to overcome the limits of data communications at sea. As a research for enhancing the connectivity and scalability of data networks at sea using the diversity and heterogeneity of the data networks on land, in this paper, a routing scheme (NLTCR) based on not conventional hop counts but distances to destination ships is introduced. The NLTCR seeks an optimal route by normalized distances to a destination, and transmission characteristics of applications and carriers. Performance is evaluated and compared with those of the max-win (MWR) and the normalized transmission characteristics (NTCR) based schemes.

A routing scheme called MCS-NLTC using a self-configuration marine network model and the diversity and heterogeneity of broadband wireless access technologies is newly proposed. The MCS-NLTC algorithm selects optimal nodes and carriers for every hop in optimal routes based on not conventional hop counts but normalized distances to destination ships (location information of destination ships). Normalized transmission characteristics of applications and carriers are considered to get optimal routes as well. The location information enhances convergence speed to get destinations, which makes the route search time faster. Evaluated performances are compared with those of the schemes based on max-win (OMH-MW), and normalized transmission characteristics (MCS-NTC).
