Abstract: The present invention relates to a method for clustering of a vessel USN with designation of a cluster head in a vessel USN system, wherein the method comprises the steps of receiving information on residual energy from multiple nodes and a cluster head after one cycle expires; and designating a cluster head among the nodes based on the information on residual energy. According to the present invention, energy consumption on communications among the nodes can be reduced since the designation of a cluster head based on residual energy is used. And, the cluster head is not replaced frequently, thereby providing economic feasibility and stable communications among the nodes. In addition, when a fault occurs in the cluster head of the vessel USN, the entire re-clustering can be avoided and rearrangement of overlapping cluster heads is not required. Moreover, it is possible to reduce inconvenience resulting from communications required for exchange of state information among cluster heads.

Abstract: An algorithm of the present invention enables practical protocol and transmission technique design for maximizing transmission rate of an extended S&S network by researching an S&S network model which is extended from an ad-hoc network and coupled to a backbone network, and comparing the researched S&S network model with asymptotic performance results of point to point communications in a conventional hybrid wireless network. Moreover, the algorithm further enables efficient management of wireless resources and design of an MAC protocol and routing with lower complexity as compared with a case that only an ad-hoc network was used. Specifically, the algorithm compares how an S&S transmission capacity result changes according to a demanded service quality by considering a machine to machine communications which requires a service quality such as different delay time or a minimum message transmission success rate, and satisfies a maximum S&S transmission rate based on parameter optimization and a cross-layer cooperative method when the service quality exists.
