Abstract
In view of the special geographical environment of mine tunnel, this paper analyzes why improved Low Energy Adaptive Clustering Hierarchy (LEACH) protocols and virtual Multiple Input Multiple Output (MIMO) algorithms cause "hot zone" which shortens the life of Wireless Sensor Network (WSN) and forms the “blind area”. Based on this problem, this paper proposes a multihop non-uniform clustering algorithm named Virtual Multiple Input Multiple Output-Improved (VMIMO-I). The advantages of this algorithm are: (1) the competition radius of the cluster closer to the Sink node should be smaller, in order to the cluster head has enough energy to forward the information of other clusters. (2) There are several cooperative nodes in each cluster for multihop data transmission between clusters to save energy consumption of cluster heads; (3) There should be several clusters near the Sink node can directly transmit data to the Sink node, instead of sending all the data to the cluster head nearest to the Sink node. Then, this paper introduces the transmission process model based on this algorithm and analysis the energy consumption within and between clusters. With the simulation result on Matlab based on Minimum energy formula of VMIMO-I algorithm model, VMIMO-I algorithm is more applicable to be used in mine tunnel with lower energy consumption and more network lifetime than LEACH protocol.
Highlights
With the improvement of coal mine comprehensive automation level and the construction of perception mine IoT, the common image and disaster signal transmission which can be transmitted by LEACH protocol, which is often used in coal mine WNS, has been unable to meet today's coal mine communication goals
When the time runs to the 533rd round, the survival topologies of sensor nodes in Wireless Sensor Network (WSN) based on LEACH protocol and Virtual Multiple Input Multiple Output-Improved (VMIMO-I) algorithm are shown in Figure 4 and figure 5 respectively
These data show that VMIMO-I algorithm model has advantages over LEACH protocol applied in mine tunnel, and the life cycle of WSN is increased by 78%
Summary
With the improvement of coal mine comprehensive automation level and the construction of perception mine IoT, the common image and disaster signal transmission which can be transmitted by LEACH protocol, which is often used in coal mine WNS, has been unable to meet today's coal mine communication goals. Clustering Algorithm for Vitual MIMO energy allocation transmission protocol in literature [7]. This algorithm requires data to be transmitted from each cluster to the Sink nodes in multiple hops, which can save more network energy consumption. Aiming at ‘hot zone’ problem in mine tunnel, this paper proposes a virtual MIMO algorithm VMIMO-I based on multihop uneven clustering. This algorithm can actively balance the energy of sensor nodes especially the head nodes in WSN. It reduces the energy consumption and achieve the goal of improving the life of WSN
