Routing in Three Dimensional Wireless Sensor Networks

Sensor networks is a promising technology that can be used to avoid disasters such as fire, storm, etc. This technology needs to be improved in terms of several issues. In this paper, we focus on two issues: coverage and routing. For coverage problem, we introduce a new approach for obtaining a static covered network in the 3-D environment. This technique is referred to as the Chipset model. This would be accomplished by using a small number of sensor nodes in order to save up some energy. For routing issue, we propose a new position-based routing protocol referred to as the 3-D Sensing Spheres close to the line routing algorithm (3-D SSL). We show that this protocol achieves 100% delivery rate on top of our 3-D model. We also show that even this protocol has similar performance with the 3-D GF in terms of hop dilation and total running time, the 3-D SSL outperforms the 3-D GF in terms of Euclidean dilation. Thus, this might reduce the energy consumption of the nodes. Therefore, prolonging the lifetime of the network.
