An Optimal Polling Point Selection and Channel Allotment Scheme for Clustered WSN
Abstract
Wireless Sensor Networks are constructed to manage the environment surveillance operations. The sensor devices are deployed with its resource details. The sensing coverage, transmission coverage, battery power and bandwidth levels are considered as resource information. The clusters are formed with bandwidth and coverage details. The cluster head is selected with its capacity levels. The cluster head manage all the nodes comes under the coverage levels. All the data forwarding operations are carried out through the cluster head nodes. The data collection for the sensor networks is carried out with three elements. They are Mobile Collector, cluster heads and the sensor nodes. The elements are considered as individual layers. The data forwarding operations are performed with the distributed Load Balanced Clustering and Dual Data Uploading (LBC-DDU) method. Cluster construction and data transmission are the main tasks of the scheme. The cluster heads are paired with communication ranges. The mobile collector performs the data collection operations at the polling points. The polling point selection is carried out with the cluster head pair details. Optimal polling point selection scheme is constructed in the Enhanced Distributed Load Balanced Clustering with Dual Data Upload (ELBC-DDU) method. The bandwidth assignment tasks are managed with the channel allotment scheme. Network area verification and rescheduling process is called to manage the spatial coverage optimization for the data collection process. The data gathering scheme increases the network lifetime with minimum query response delay. Network traffic levels are minimized in the data collection framework.
