Dynamic Reconfiguration Method for Effective Cluster Based Data Transmission in WSN

WSNs are typically composed of large number of tiny sensors that are capable of sensing, processing and transmitting data via wireless links. Sensor nodes collaborate in a distributed and autonomous manner to accomplish a certain task, with no infrastructure. Power efficiency and fault tolerance are essential properties to keep the network functioning of energy depletion, communication link errors, or adverse environmental conditions, events that are likely to occur quite frequently in WSNs. The fault-tolerant topology control in a heterogeneous wireless sensor network consisting of several resource-rich super nodes, used for data relaying, and a large number of energy constrained wireless sensor nodes. So proposed clustering based code dissemination protocol for providing high link quality information. It will address the transmission efficiency due to poor communication link and identify the fault occurrence during transmission by dynamic reconfiguration. Clustering is the topology control method to reduce energy consumption and improve scalability of WSNs. In a cluster based WSN, cluster heads (CHs) consume required energy when extra work load owing to data collection, data aggregation and their communication to the base station. By choosing, sender selection algorithm estimate the impacts of senders by considering both uncovered neighbors (i.e., neighbor that do not receive an entire page) and the link qualities to those neighbor.
