Space Angle Based Energy-Aware Routing Algorithm in Three Dimensional Wireless Sensor Networks

Most of the existing routing algorithms are based on two dimension, and the results can´t be directly applied to the three dimensional wireless sensor networks, the Space Angle Based Energy-Aware Routing algorithm in three dimensional wireless sensor networks is designed in this paper. Firstly, the Iterative Split Clustering Algorithm for dividing the network nodes is proposed. Secondly, we design the Space Angel Energy Routing algorithm to transfer data within the clusters and between the clusters respectively, achieving the goal of less energy consumption and extending the network lifetime. We simulate and implement the algorithm and evaluate the performance based on topologies with different scales, and get a conclusion that by comparing with the typical algorithm, the routing algorithms proposed in this paper are able to reduce the network energy consumption effectively and extend the network lifetime.
