The mobile sink can increase the efficiency of wireless sensor networks. It moves in a monitored environment and collects the network nodes information. Thus, by the sink we can balance the power consumption and increases the network lifetime. Determining path of the sink's movement is usually modeled as an optimization problem where finding optimal solutions require collecting value of all the...

Air quality and personal pollutant exposure measurement are important for the health and productivity of individuals. Accurate measurement of personal exposure is challenging because of the spatially and temporally heterogeneous distribution of pollutant concentrations. We propose to use low-cost and miniature mobile sensor networks to provide real-time measurement of the environment directly s...

A swarming mobile sensor network is comprised of a swarm of wirelessly connected mobile robots equipped with various sensors. Such a network can be applied in an uncertain environment for services such as cooperative navigation and exploration, object identification and information gathering. One of the most advantageous properties of the swarming wireless sensor network is that mobile nodes ca...
