Item Dynamic coverage by homogeneous mobile sensor nodes using tri-hexagonal scheme(Springer Verlag service@springer.de, 2014) D'Souza, R.J.; Santoshi, G.Mobile sensor nodes (MSNs) are energy constrained, recharge, and replacement of battery is not possible after deployment. They spend more energy during their traversal and can be conserved by minimizing the traversal. High degree of coverage is preferred in many applications. Energy conservation is one of the most demanded researches. MSNs with variable sensing range are best suitable in search-related operations. Degree of coverage can be increased whenever the situation demands. © 2014 Springer India.Item Mobile sensor node traversal schemes using coverage based pattern movement with uniform energy depletion(Institute of Electrical and Electronics Engineers Inc., 2014) D'Souza, R.J.; Santoshi, G.In this work a rectangular Region of interest (ROI) is covered with Mobile Sensor Nodes (MSNs) using coverage based pattern of movement. ROI is divided into equilateral triangles and squares in tesselation fashion to provide complete coverage without coverage holes. MSNs are moved along the vertices of polygons to have optimized movement cost. All MSNs should travel an approximately equal distance, otherwise the MSN which travels longer distance depletes more energy compared to the MSN which travels shorter distance. We show that, the ROI partition in tessellation fashion is application specific and plays a great role in uniform energy depletion of the MSNs during the traversal. An improper partition may lead to an unbalanced movement cost and non-uniform residual energy. © 2014 IEEE.
