Randomized fault-tolerant virtual backbone tree to improve the lifetime of wireless sensor networks ?
Need of energy efficient backbone routing for WSNs. FTVBT (virtual backbone tree construction algorithm) proposed to minimize energy consumption. Identifies hotspots, distributes dependents across tree nodes and the distribution is also bounded. Randomized FTVBT elects tree nodes based on a weight function and increases network lifetime.
