Efficient clustering for Mobile Wireless Sensor Networks

Wireless Sensor Network (WSN) applications require reliable data communication and maximized network lifetime. Both requirements are more demanding in Mobile Wireless Sensor Networks (MWSN) as compared to static WSN. In cluster-based MWSN it is a challenge is to receive data reliably at the cluster-head. This can be achieved by conserving network energy and maintaining reliable connectivity between the cluster-head(s) and the sensor nodes. Most of the cluster-based MWSN protocols can acquire data with some reliability but at the cost of heavy power consumption, thus they limit the network lifetime. In this paper we have presented a virtual grid-based distributed clustering (VGDC) solution for MWSN that gives data reliability up to 30% more than existing solutions at the cluster-heads. Our proposed VGDC scheme also reduces energy consumption resulting in increased lifetime of the network.
