Greedy geographic routing protocol for 3D wireless sensor networks
Hongyan Wu · Transducer and Microsystem Technologies · 2011
There are some drawbacks like transformation between different dimensions in existing routing protocols for 3D wireless sensor networks(3D WSNs).A greedy geographic routing(GGR)protocol for 3D WSNs is proposed.The protocol commonly uses greedy forwording(GF)algorithm to transfer the packet.At the same time,3D rolling ball traversal(3D-RBT)algorithm is employed to avoid routing void problem conduced by GGR algorithm.The experimental result shows a high routing success ratio and a satisfied routing hop number,especially when the node density is low.
