Dynamic Hierarchical Sleep Scheduling for Wireless Ad-Hoc Sensor Networks
This paper presents two scheduling management schemes for wireless sensor networks, which manage the sensors by utilizing the hierarchical network structure and allocate network resources efficiently. A local criterion is used to simultaneously establish the sensing coverage and connectivity such that dynamic cluster-based sleep scheduling can be achieved. The proposed schemes are simulated and...
متن کاملScheduling algorithms for wireless ad-hoc sensor networks
In this paper, we define a simple discrete mathematical model for wireless ad-hoc sensor networks and study the problems of data distribution and data collection which arise in those networks. We show how those tasks can be optimally performed on tree sensor networks that use directional antennas. Furthermore we compare the performance of a network equipped with directional antenna elements wit...
متن کاملDynamic Energy Efficient Topology for Wireless Ad hoc Sensor Networks
Wireless Sensor Ad hoc Networks (WASNs) are self organizing, self-configuring and multi-hop wireless networks, in which each node communicates with other nodes directly or indirectly through intermediate nodes without any infrastructure. Besides these characteristics challenges like limited energy, dynamic topology, low bandwidth and security exists. The arrangement of nodes in WASN is called t...
متن کاملWireless Ad Hoc Sensor Networks
Wireless Ad Hoc Sensor Networks (WAdSNs) have become an important research area in the last ten years. Main contributions have focused on the development of new hardware, software, and protocols supporting distributed applications. In these kinds of networks, cooperation is a key issue, especially when nodes collaborate with their neighbors and with the whole network, considering it as a single...
متن کاملDynamic Sleep Scheduling using Online Experimentation for Wireless Sensor Networks
In sensor networks it is critical to conserve energy as replacing batteries is an expensive manual operation. Energy needs to be saved when events are detected as well as when there is no event. Current sleep-scheduling approaches for sensor networks that address energy consumption either only save energy when idling or have high latencies and low channel utilization. Our contribution is an ene...
