Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Electronics and Communication Engineering Summary: Wireless sensor networks face several challenges in field deployments due to strict limitations in nodes hardware capabilities. We propose two temporal radio duty-cycle frequencies update mechanisms namely: a distributed mechanism in which a WSN sink node collects network-wide statistics and broadcasts thresholds to the nodes to adjust their duty cycles and an autonomous mechanism in which each node individually updates its duty-cycle based on its measured statistics. Our simulations show significant gains in network life time while maintaining sensory packets delivery ratio at same levels compared with static schemes
