Recent advances in wireless communication and micro-electro-mechanical
systems (MEMS) have led to the development of implementation of low-cost, low
power, multifunctional sensor nodes. These sensor node are small in size and
communicate untethered in short distances. The nodes in sensor networks have
limited battery power and it is not feasible or possible to recharge or replace the
batteries, therefore power consumption should be minimized so that overall
network lifetime will be increased. In order to minimize power consumed during
idle listening, some nodes, which can be considered redundant, can be put to
sleep. In this thesis study, basic routing algorithms and duty cycle control
algorithms for WSNs in the literature are studied. One of the duty cycle control
algorithms, Role Alternating, Coverage Preserving, and Coordinated Sleep
algorithm (RACP) is examined and simulated using the ns2 simulation
environment. A novel duty cycle control algorithm, Sink Initiated Path Formation
(SIPF) is proposed and compared to RACP in terms of sleep sensor ratio and time
averaged coverage.
