A virtual cluster scheme technology for efficient wireless sansor networks

Abstract

Once nodes are deployed in the wireless sensor network, as it is impossible to replace batteries, the amount of transmittable information depends on how to use the limited energy efficiently for longer network life. Virtual Cluster Routing (VCR) builds the efficient virtual cluster considering node compactness, selects the closest node and manages the routing table to reduce overhead significantly by referencing routing table information within the virtual cluster without communicating with other clusters via the head, and has a lower transmission delay and higher survival time than the routing scheme. © 2014 Springer-Verlag Berlin Heidelberg.
