WU Qing, ZHANG Shen, LI Shu-qiao, et al. An improvement of LEACH routing protocol applied in underground mine[J]. 2012, 31(4): 23-25. DOI: 10.13873/j.1000-97872012.04.016.
The construction intention of internet of things(sensor mine)research center is described.The advantages and weaknesses of LEACH protocol used in underground mine are analyzed.Aiming at the special geographical environment in underground mine
the reason why the"hot zone"is formed in the underground mine by LEACH protocol is analyzed
and the importance of the total energy consumption and the network lifetime of sensor networks in underground mine is derived.On the basis of this
the applicable LEACH—I protocol for underground mine is proposed.The simulation result on Matlab
LEACH—I protocol is more applicable to be used in underground mine with low energy consumption and more network lifetime than LEACH.
