Abstract
We propose a grid-based routing protocol which divides the network area for large side lengths of square cells and exploits cell rotation. The proposed scheme divides each cell into multiple sub-cells, and because the maximum transmission range is a fixed value, side lengths of square cells can be enlarged. Therefore, the number of relay nodes between the source node and the mobile sink is reduced. Simulation results show that the proposed scheme improves the packets latency and energy consumption efficiency.
