Virtual Infrastructure Based Dynamic Routing using Mobile Sink

A Virtual Infrastructure Based Dynamic Routing using Mobile Sink technique for Duty Cycled Wireless Sensor Networks is proposed which uses both virtual infrastructure and duty cycled mechanism. Here virtual infrastructure implies that only subset of nodes participates in route reconstruction process. The duty cycling mechanism enables the nodes to switch between active/sleep modes to minimize the energy consumption. The results demonstrate that the proposed VIDRDC scheme decreases the energy consumption and improves the network lifetime in comparison to the existing VGDRA scheme.
