Abstract:
A Wireless Sensor Networks (WSN) comprises of numerous sensor nodes which can be
used as an effective tool for data collection in different applications like remote health care,
war field surveillance, environmental monitoring, smart farming etc. WSN has rapidly gain
massive global attractions which gives a new perspective to deal with things contrary to
the traditional approach of performing tasks. WSN nodes are multifunctional, low-cost
processing and sensing unit with a limited pre-installed battery capacity that are directly or
indirectly connect and collaborate with each other. These nodes organize themselves in
their environment to gather information, process it, share and transmit collected data at
end-point that provide unattended operations or less human intervention which reduce
financial cost and minimize the risks. As GDP is the key factor of the country in terms of
economic health and services capability in an international market from various industries
like textile, manufacturing, agriculture etc. So, the minimization of financial losses to
increase the overall GDP is utmost important. One of the major challenges of WSN is to
collect aggregated data with minimum energy consumption from sensor nodes to base
station. In this thesis, the focus is to enhance the network performance with minimum
energy consumption based on the Hybrid Multi-Tier Mobile Data Collector (MDC) based
Cluster / GRID routing protocol. This protocol makes use of a GRID / Cluster based Multi
Tier architecture and uses multi-hop communication mechanism between clusters and base
station. The Hybrid Multi-Tier MDC based protocol shows substantial improvements in
minimizing sensor nodes’ energy consumption and improve the network life. Hence, the
better instantaneous monitoring, increase administrative power on going tasks, in depth
historical insight, and smart decision making become possible with minimal investment
that strength farmers and assure higher revenue.
