The study of a wireless multimedia sensor network self-organization protocol for coal mine

Mine disaster occurred, underground power and communications systems were severely damaged, and cause great difficulties for the relief effort. Therefore it has some practical value to design a suitable self-organization network of underground. This article proposes a wireless multimedia sensor network Self-organization protocol for mine rescue .To quickly form an adaptive hierarchical structure which using sink as a top layer node, this protocol can be divided into three stages: backbone network quickly establishing, self-organization as some cluster, self-adaptive and adjusting stage. Simulation result shows that this protocol can quickly establish a self-organization network and has a good performance in prolonging the lifetime of network and balancing nodes energy.
