Installing a mobile sink on the public vehicle, which is a path-constrained vehicle, to collect data in a mobile sensor network can lower maintenance cost. However, immediately sending the data packet to the mobile sink when it arrives does not guarantee the shortest path, leading to high energy consumption. Meanwhile, immediately sending the data packet to the closest future position of the mobile...
Underwater Wireless Sensor Networks (UWSNs) enable a wide range of aquatic applications. But the underlying physical layer technology makes the development of efficient data collection and routing schemes for UWSNs a challenging issue. It is important for the UWSNs to have maximum possible lifetime, because the recharging or replacement of sensor nodes after deployment is almost impossible. We propose...
This paper presents the routing recovery problem of mobile sink wireless sensor networks (mWSNs), which is caused by the sink mobility. We propose an immune orthogonal learning particle swarm optimization algorithm (IOLPSOA) based routing recovery method to build and optimize the alternative path, in order to repair the broken path and maintain the available route from the source nodes to the mobile...
