RELIABLE AND EFFICIENT DATA ACQUISITION IN WIRELESS SENSOR NETWORK

ABSTRACT It has been observed that the sensor nodes are deactivated or damaged when exposed to specific radiations, change in temperature leading to the energy draining issues of the sensor nodes. This failure leads to the temporary isolation of the nodes from the wireless network which results in the formation of the holes. These holes are dynamic in form and can increase and decrease depending upon the factors affecting the failure to the sensor nodes. So a solution has been presented where the WSN functions in dual mode i.e. Radio frequency and the Acoustic mode so that the information can be transferred securely. With the help of the Dynamic Source Routing, Bridge protection algorithm and clustering techniques, more efficiently and reliably the data is transferred from the source to the destination node. Depending on this a survey has been taken where number of factors are studied so that the performance of the system can be increased. We use java based simulator as simulation platform to demonstrate proposed model implementation.
