ROBUST PATH RECONSTRUCTION IN LARGE SCALE WIRELESS SENSOR NETWORKS

Abstract: The demand for the compact and small-sized electronics device is increasing in present days, and many of the organizations and researchers have adopted these demand and have succeeded too. Wireless sensor devices are made with more compact and small sized and also the large scale Wireless Sensor Networks (LSWSNs), which are also developed with more number of sensor nodes. These LSWSNs means the WSNs were having high density or of the large area of the network. Mainly a WSNs are composed of Sensor Nodes (SNs) which are placed in a pattern, by which more data can be gathered and transferred to the base station (BS) or also known as Sink. The path determining process from source to destination for data transmission is generally known as routing. In most WSNs routing of incoming data can be determined by the network layer. The SNs at the source cannot reach the sink node directly in multi-hop networks, hence intermediate SNs need to relay their respective packets. Mainly the routing path of every packet is helpful in understanding the network performance. The analysis of routing path is necessary to route path reconstruction. There have been many efforts made to address the per-packet path reconstruction problem in WSNs. In this project we propose a novel Pathfinder scheme. The evaluation will be done using Matlab tool.
