Design of Novel Node Distribution Strategies in Corona-Based Wireless Sensor Networks

Considering coverage, efficiency, and durability, three non-uniform node distribution strategies for a corona-based Wireless Sensor Network (WSN) are proposed in this paper. To derive lower bounds on sensor nodes in coronas, the authors investigate the optimal node placement based on coverage. They then prove the feasibility of balanced energy depletion for a primitive Geometric Node Distribution (GND) and a primitive Energy Proportional Node Distribution (EPND). Applying the optimal node placement and GND enables them to propose the first strategy (Strategy I) to reach completely balanced energy depletion.
