Enhancement of lifetime in static sensor network is an exigent task owing to limited power supply and restricted accessibility of sensor nodes. At every round of data transfer not all source nodes necessitate sending data to sink and hence tune itself to sleep mode. This paper utilizes the sleep-mode nodes as relays in transferring data from a transmitter to receiver for boosting energy efficiency in the network. Simple geometrical properties in modeling are used in the mathematics involved for choosing the most practicable sleep-mode node to relay the data. Moreover, such an approach requires the knowledge of geographical location of only the nodes in-between the transmitter and receiver. The simulation model use Poisson distribution to determine the sleep-mode nodes. This model is imposed on a range of data routing and clustering algorithm present in literature and results indicated a significant improvement in lifetime using it.
