Energy Efficient Synchronization Scheme Using Heterogeneity with Mobile Sink in WSN
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
The energy of the sensor nodes in the Wireless Sensor Networks (WSNs) is a limited resource and causes the fluctuation in the lifetime of the network. Also, the throughput and delay of the network depend on how long the network sustains i.e. energy consumption of the network. One way to increase the feasibility of network is the introduction of heterogeneous nodes regarding energy, and the other is to synchronize the local clock of the member node with the global clock of the cluster head and the sink in the network. Earlier, a typical WSN was composed of static sensor nodes and a static sink placed inside the observed region. In such a setup, the major energy consumer is the communication module of each node. In practice, multi-hop communication is required for sending data from sources to sink nodes. Consequently, the energy consumption depends on the communication distance. So in this paper Sink mobility is introduced along with the node heterogeneity based synchronization scheme in order to reduce the energy consumption of the network and hence increasing the lifetime of the network as compared to the existing Node Heterogeneity aware Energy Efficient Synchronization Algorithm (NHES).
