Mobile Sink: A novel and Profitable approach for data collection

Abstract

WSNs will be an instrumental system for data aggregation in future. The data aggregation task required to collect the data from sensor and routed to base station or sink node. To forward the data from one node to another node, we need some systematic way which is known as routing algorithm. They define a specific rule about where to forward the packet. Tradition way all the node in WSNs consider as steady node. Where, node uses one of the routing algorithms to forward the packet to best node toward the destination and ultimately it reached to the base station or sink node. The new approach rather than node send the data to the sink node, a mobile node or rendezvous node visit the particular path at regular interval and collect information form
the node. This approach avoids the direct long distance transmission of packet, which leads to save energy of network. This paper covers some important algorithm of mobile sink data collection approach.
