Abstract

Wireless sensor networks (WSNs) consist of several nodes with limited and non-rechargeable power resources. Therefore, energy efficiency and network lifetime depend on the utilize way of sensor nodes. Recently, some methods and strategies have been employed in this regard. Most of them could improve network lifespan to an acceptable level. Energy hole is one of inherent problems which can decrease the network lifetime to 89%. In multi-hop WSNs, the sensors located closer to sink must relay more data packets in comparison with other ones, thus their power supplies will be exhausted earlier than other nodes. Whereas, the sensor nodes belonging to other layers still have required energy for transmitting their data packets. This asynchronous energy depletion is considered as a problem. In this paper, we present a mathematical model for non-uniform node deployment for corona-based WSNs. According to results, Optimal Number of Nodes Deployment Method (ONNDM) enhance the network lifetime via balancing energy consumption and workload among coronas. In ONNDM, the optimum number of nodes in each corona is obtained by a mathematical formula, which can outperform other proposed strategies.
