Wireless sensor networks are finding application in heterogeneous scenarios with varied deployment constraints and consumer requirements. Effective instrumentation, visualization, archival, analysis, and third-party notification are the cornerstones of any sensor network deployment. Unfortunately, the manifestation of these generalized needs can differ widely between deployments leading to creation...
Graded precision localization is the process by which mobile heterogeneous sensor nodes localize themselves to varying levels of precision, even though they co-exist and operate in a common framework. Some nodes may only need to compute their approximate location at infrequent intervals. Others may need to be continuously and precisely localized. Since GPS is not available indoors, we need to provision...
Wireless Sensor Network (WSNs) are collection of small Sensor Nodes (SNs) which are capable of performing multiple tasks such as data aggregation, processing and communication either to other SNs or to the Base Station (BS). As SNs are battery operated, so efficient utilization of energy during various operations in WSNs is one of the major issues which requires special attention. It has been observed...
