Energy efficient clustering based 3-rank heterogeneous network model for wireless sensor network
Deepali Agarwal, Avdhesh Gupta · 2015
Now-a-days many advanced technologies have been innovated in the field of Wireless Sensor Networks (WSN). The main problem regarding wireless sensor network is the improvement of its energy efficiency in the clustering protocol. Most of the direction-finding or path finding challenges are faced by WSN in terms of node deployment, energy consumption, communication range, fault tolerance, quality of service, etc. In this paper, the impact of heterogeneity of nodes are related to their nodes energy are considered. In wireless sensor networks nodes are divided into three types (type-1, 2, 3) based on their energy. We assume that nodes of type-1 energy are equipped with the additional energy resources than type-2 nodes and type-2 is having more energy than type-3 nodes. It is also assumed that the sensor nodes are arbitrarily disseminated. The dimension and sensor field and the coordinates of sink are known in advance. In homogeneous clustering protocol, all sensor nodes have same amount of energy. In this work we worked on energy efficient heterogeneous clustered scheme for WSN. Also we have simulated the results and find that the proposed approach in heterogeneous clustering is more effective in lifetime as compared to other protocols.
