Revisiting Key Predistribution Using Transversal Designs for a Grid-Based Deployment Scheme

International Journal of Distributed Sensor Networks, 2009, vol. 5, issue 6, 660-674

Abstract: We consider a grid-based deployment scheme in which keys are predistributed in sensor nodes following a transversal design. This scheme was first proposed by Ruj, Maitra, and Roy in [ 19 ]. In their scheme the RF region was considered to be the a square of appropriate dimension. In this article, we consider the RF region to be the Lee sphere of appropriate radius. This is a better approximation than the square RF region and all calculations of connectivity and resiliency is done with respect to this parameter.
