Design of cluster-chain based WSN for energy efficiency
Soumita Sen, Chandreyee Chowdhury, Sarmistha Neogy · 2016
Energy consumption becomes a severe issue in wireless sensor network (wsn), since the tasks of sensing, processing and transmission of data to distant base station or sink are done by battery dependent sensor nodes. A lot of energy-efficient techniques are emerging daily to cope with this energy constraint issue of wsn. In this paper we introduce a combination of cluster and chain based data delivery approach to reduce data redundancy and energy consumption of a static wsn. We also consider nodes with dual radio that are capable of transmitting at two energy levels. Finally, we have shown the prolongation of network lifetime by varying the data path and transmission power of radio as per application requirement.
