摘要： Broadcasting is an important operation in the wireless network to disseminate information throughout the entire network. Flooding is a simple mechanism to realise broadcasting, but it has high redundancy of retransmissions, leading to low transmission efficiency. In this paper, we propose a 3D broadcast protocol, called 3DOBP (3–Dimensional Optimised Broadcast Protocol), to achieve optimised transmission efficiency by partitioning the 3D space into multi–layer hexagonal prisms of a hexagon ring pattern in each layer. The transmission efficiency of the proposed protocol is 1/π, which is higher than those of polyhedron–filling broadcasting approaches using cubes, hexagon prisms, rhombic dodecahedrons, and truncated octahedrons. 其他題名： ijahuc 出版者： Genève: Inderscience Publishers 出版日期： 2013-01-01 出處： International journal of ad hoc and ubiquitous computing, 2013-01, Vol.12 (4), p.205-215 版權： 2014 INIST-CNRS 識別號： ISSN: 1743-8225 識別號： EISSN: 1743-8233 識別號： DOI: 10.1504/IJAHUC.2013.052863
