Elongate the lifetime of the network using grid based cluster with backbone spanning tree for wireless sensor networks

Wireless sensor network is collection of tiny sensor nodes; those are homogeneous and heterogeneous types. Power consumption is the critical issue in the sensor network because battery has limited power and nodes deployment process is also consumed much energy; it is crucially impact on the lifetime of the network. A Grid Based Clustering with Spanning Tree Routing (GCSTR) approach is proposed to improve the lifetime of the network for WSN. A minimum energy consumed spanning tree is constructed on the Cluster Head (CH) of clusters. Cluster heads act as node of a spanning tree. All CHs report to the sink, along specific path i.e. edges of spanning tree. Whenever evaluate the number of inter transmission and intra transmission before construct the spanning tree over CHs then calculate the lifetime of the network. Simulation Result vigorously effect on the lifetime of network as compared LEACH and OCR. Simulation has been done with the respect to energy consumption; lifetime of the network over the number of rounds and packets transmits to the sink.
