It also shows an overall reduction of energy consumption by the entire network. Therefore energy awareness is an essential consideration for wireless sensor network. In this paper, two algorithms have been investigated for application of wireless sensor network in Railway Disaster Prevention and Safety Monitoring System, which are Advanced Direction-aware Algorithm and Cluster Head Selection Algorithm based on the Dynamic Energy Threshold respectively. Sensor networks are one of the fastest growing areas in broad wireless ad hoc networking field. Series: Volume 6 Number 2. When the environmental conditions are stable, a typical Wireless Sensor Network (WSN) application may sense and process very similar or constant data values for long durations. To reduce energy consumption of sensor nodes sleep-wake scheduling algorithm is an effective mechanism .This algorithm also prolong the lifetime of these energy constrained wireless sensor networks. WSN nodes are in general battery-powered, thereby and efficient usage of their energy budget is of paramount importance to avoid performance degradation in IoT applications. Year of Publication: 2016. However, sleep-wake scheduling could result in substantial delays because a transmitting node needs to wait for its next-hop relay node to wake up. A sensor node, typically, contains signal-processing circuits, micro-controllers and a wireless transmitter/receiver antenna. Wireless Sensor Networks (WSNs) are an emerging technology with a wide range of potential applications. Reducing Radio Energy Consumption of Key Management Protocols for Wireless Sensor Networks Bo ... Due to emerging low power, embedded and wireless technologies, distributed sensor networks can be realized by establishing networks among a large amount of tiny and resource constrained sensor devices. A sensor network has many sensor nodes with limited energy. A lot of work has been done in the field of Wireless Sensor Networks (WSN) in recent years. Energy consumption is a main research issue in wireless sensor networks; and particularly in those where nodes collaborate to reach a goal. However, due to … Cached. This is a common behavior of WSN nodes that can be exploited for reducing their power consumption. When we increase the number of nodes in the network, sensor nodes become closer to each other as the area in which sensor nodes are placed is maintained constant. Therefore, power efficiency is a critical requirement for wireless sensor networks. A Fuzzy Approach for Reducing Power Consumption in Wireless Sensor Networks: A Testbed With IEEE 802.15.4 and WirelessHART Abstract: The rapid growth in the adoption of wireless sensor networks (WSNs) is motivated by the advantages offered with respect to wired systems, such as cost-effectiveness, easiness of installation, scalability, flexibility, and self-organization. In the IEEE 802.15.4 standard the SNR can be inferred through the radio reported link quality or received signal strength, and an extension to the standard leads to highly dynamic and accurate rate selection.

In wireless sensor networks, sensor nodes close to sink have more traffic loads, they will quickly deplete their energy and it will finally lead to network partition and isolate the sink. The use of variable data rate can reduce network latency and average power consumption, and automatic rate selection is critical for improving scalability and minimizing network overhead. Energy saving is one of the critical issue for sensor networks since most sensors are equipped with non-rechargeable batteries that have limited lifetime. Wireless Sensor Networks have gained lot of attention in the last decade due to their low power consumption nodes and mobility. To solve this problem it is possible to use mobile sink in the network.
