Abstract:
Wireless
sensor network has proven to be a reliable tool for monitoring
applications. Most of these applications expect sensor nodes to operate
with the desired level of fidelity for years especially those deployed
for long distance. However, sensors with limited energy and sensing
range may not be able to meet that expectation. Consequently, node
placement is considered one of the most important factors that can cause
non-uniform energy consumption, limit the sensing range and shorten the
network lifetime. Therefore, sensor nodes should be strategically
placed to tackle these challenges. There are many node placement schemes
that have been proposed so far but most of these schemes are not
applicable for the linear topology (i.e. Pipelines Monitoring). In this
thesis, we study the node placement approaches of WSNs used for pipeline
monitoring. Since most of the existing placement approaches are not
efficient especially for reliable communication, required fidelity and
desired lifetime, two novel placement approaches based on clustering
techniques are proposed. These approaches prominently, gather the sensor
nodes based on their power levels to balance the energy consumption
practically among the same cluster. The required fidelity is considered
by limiting the distances between nodes. Extensive simulation
experiments based on our proposed schemes have been conducted. The
simulation results demonstrate outstanding performance compared to the
greedy approaches in terms of minimizing the power consumption, reducing
the number of exchanged messages and increasing the lifetime. Moreover,
proof-of-concept experiments using TelosB motes have been carried out
for validating the proposed approaches.
All faculty members, researchers and students are cordially invited to attend.
