A New Conception of Information Requisition in Web of Things


  • Computer Science and Engineering, Thapar Univeristy, Patiala – 147004, Punjab, India


Objectives: The dynamic spanning tree approach from Requester Node to Responder Node has been proposed for WoT for information requisition. The objective is to eliminate data redundancy in multipath communication. Methods: A spanning tree algorithm has been proposed to create a dynamic single path from Requester Node (RN) to Responding Node (ReN) in WoT Graph. Before actual communication a virtual path is established between RN and ReN which helps in the reduction of multipaths, cycles and data duplicacy. Findings: The approach is implemented and tested on different scenarios of WoT graphs in NS-2 simulator and shows good results in terms of information requisition. In a WoT graph communication multiple path exists between sender and receiver nodes causing duplicate data packets and high traffic intensity in the network, while in WoT spanning tree there is a single path. Therefore, the network throughput and the efficiency increases manifold. Application: The rapid growth of WoT enabled internet applications, decision making, marketing, healthcare, monitoring and interlinked controlled devices generates high demand for reliable and timely information.
