Optimization coverage of wireless nodes for target probabilistic positioning in underwater sensor network

As a class of narrow band structures such as dock, bridge and dam, chain-type networks are applied to monitor and track underwater targets. This paper proposes a coverage strategy for probabilistic positioning of mobile targets, which can balance the coverage and positioning performance of underwater sensor network. Based on careful analysis characteristic of network architectures, multiple relay nodes integrated with non-uniform deployment are designed in the consideration of the extensibility of underwater sensor network, which consists of common sense nodes, relay nodes and a base station. The probabilistic positioning model for mobile targets is devised with the support of node optimization coverage. Furthermore, the simulation experiments have been implemented in order to evaluate the proposed algorithm performance for targets probabilistic positioning.
