A Catenulate Hierarchy WSN Topology Control Algorithm Used in Coal Face
Deqiang Cheng, Yu Jin · 2008
According to the characteristics of coal face and laneway landform, a catenulate hierarchy of wireless sensor network (WSN) is proposed including its topology control algorithm. For establishing bottom infrastructures of WSN, the distance between cluster nodes and cluster headers is defined, and the cluster headers selecting algorithm is analyzed. In the top backbone transmission network, a HETCA (hierarchy energy- effective topology control algorithm) is put forward to selecting routing nodes for multi-hop routing within WSN. The theory analysis and simulation results show that HETCA can balance WSN loads to save energy used in transmission, and extends the lifetime of whole network.
