Dependable and Energy-Efficient Communication Infrastructure

In recently years, as the great progress of
wireless communication and sensor
technology, to diffuse wireless sensors in
certain areas to accomplish specify task
has became very popular research issues.
Therefore, it will suffer from some
problems and challenges in wireless sensor
network, especially the limited energy
resource. This is because the nodes in
sensor network often have no fixed power
supply, and they maintain their power by
batteries. If several sensors exhaust their
energy, it leads to degradation of network
life time.
Thus, to develop energy-efficient
communication infrastructure is a very
important key technology of wireless
sensor network. This research plan
develops network topology-control
technology to archive this objective. Our
simulation results also show that it can
efficiently lower the rate of energy
consumption and increase the network life
time by network topology control.
