Abstract

Data-Collection in wireless sensor networks (WSNs) has one of the crucial performance metric called lifetime of a network to be evaluated where the environment is sensed periodically by the sensor nodes that are battery-powered. The samples collected is forwarded to a sink node. We have proposed a model to estimate network initialization from the nodes gets activated in the entire lifetime of the network until these nodes completely are disabled. The energy consumption required in data collection in WSN is then determined. The sensor node’s lifetime, energy consumption and traffic load is estimated in the entire lifetime of the network. Also, the spatial and temporal energy hole evaluation is investigated and the analytical results are applied to WSN routing for balancing the energy consumption and improve the network lifetime. In order to estimate the network lifetime and energy consumption while data collection in WSN, simulation results are provided to demonstrate the validity of the proposed analytic model.
