This work shows that, ROI partition plays great role in hole free coverage and makes the MSNs have optimized movement cost with fault tolerant support.Abstract:
Mobile sensor nodes (MSNs) are equipped with locomotive can move around after having been deployed. They are equipped with limited energy. A large portion of energy is drained during the traversal. In order to extend the life time of a MSN, the traveling distance must be minimized. Region of interest (ROI) is covered with multiple MSNs using coverage based pattern movement. When a group of MSNs are deployed to cover a given ROI, all the deployed MSNs should travel an approximately equal distance. Otherwise, the MSN which travels longer distance depletes more energy compared to the MSN which travels a shorter distance. In this work we show that, ROI partition plays great role in hole free coverage and makes the MSNs have optimized movement cost with fault tolerant support.read more

Mobile sensor nodes scheduling for bounded region coverage
TL;DR: This work formulates the problem of scheduling the MSNs in distributed manner so that the entire region is covered without coverage holes with minimum energy depletion and some computationally practical algorithms for multiple MSNs with fault and non-fault tolerant support are presented and their performances compared.

TL;DR: A Mobile Traversal Algorithm (MTA) is proposed, for mobile sensor nodes to cover a rectangular region of interest (ROI) and makes MSNs to travel shorter distances to extend effective operational duration of the network and also to provide fault tolerance mechanism.

Dynamic Coverage by Homogeneous Mobile Sensor Nodes Using Tri-Hexagonal Scheme

TL;DR: Mobile sensor nodes (MSNs) are energy constrained, recharge, and replacement of battery is not possible after deployment, so MSNs with variable sensing range are best suitable in search-related operations.
