  An economic zone requires continuous monitoring and controlling by an
autonomous surveillance system for heightening its production competency and
security. Wireless sensor network (WSN) has swiftly grown popularity over the
world for uninterruptedly monitoring and controlling a system. Sensor devices,
the main elements of WSN, are given limited amount of energy, which leads the
network to limited lifespan. Therefore, the most significant challenge is to
increase the lifespan of a WSN system. Topology control mechanism (TCM) is a
renowned method to enhance the lifespan of WSN. This paper proposes an approach
to extend the lifetime of WSN for an economic area, targeting an economic zone
in Bangladesh. Observations are made on the performance of the network lifetime
considering the individual combinations of the TCM protocols and comparative
investigation between the time and energy triggering strategy of TCM protocols.
Results reveal the network makes a better performance in the case of A3
protocol while using the topology maintenance protocols with both time and
energy triggering methods. Moreover, the performance of the A3 and DGETRec is
superior to the other combinations of TCM protocols. Hence, the WSN system can
be able to serve better connectivity coverage in the target economic zone.
