The unique characteristic of the underwater acoustic communication channel force development of new protocols for underwater acoustic sensor networks. Especially, the pretty slower propagation speed of acoustic signals in underwater should be taken into consideration. This paper constructs a link scheduling model on medium access control (MAC) layer for multihop underwater acoustic sensor networks...
In this paper, we consider a practical underwater data collection network, where one destination needs to collect data from multiple underwater nodes. With the conventional automatic-repeat-request (ARQ) protocol, the destination requests retransmission from each node individually without any node cooperation. We propose two protocols, selective relay cooperation and dynamic network coded cooperation,...
This paper analyses the principle and problems of the classical contract net in the application, it is proposed that contract business extension contract nets based on the concurrent trading mechanism. This mechanism makes the task allocation realize quickly. It reduces network communication cost between the agents, improves the efficiency of multi-agent system collaboration and the overall system...
Interest in Underwater Acoustic Networks (UAN) has grown rapidly with the desire to monitor the ocean, depending on the potential capability of UAN to support a large variety of applications, such as monitoring of equipment and natural events. Moreover, these applications may have requirement for saving energy at each node adaptively in the underwater power limited system. In this paper, we establish...
