In underwater sensor networks, localization is one of the most important issues because sensor nodes are considerably difficult to be deployed at determined locations. Since range-based schemes require additional device and precise time synchronization for measuring distances in underwater environments, range-free schemes are promising in the view point of energy consumption and implementation. Coarseness...
Using controlled mobile elements is a promising approach to collect data from sensor nodes. It is very important to calculate a number of near-optimal routes for the fusion nodes that incrementally collect the data. Based on the multi-tier mobile network model, a new moving control strategy is proposed. This method first divides the monitoring field into several sub-regions so that fusion nodes can...
The expected lifetime of any wireless sensor network is a critical issue as sensor nodes are powered by small batteries. One effective approach for energy conservation, especially in high density networks, consists on switching alternatively nodes in sleep/active modes, while ensuring at the same time continuous monitoring (i.e., coverage and connectivity). In this paper we propose a novel approach...
