In wireless sensor networks, adversaries can injectfalse data reports via compromised nodes and launch DoS attacks against legitimate reports. Recently, a number of filtering schemes against false reports have been proposed. However, they either lack strong filtering capacity or cannot support highly dynamic sensor networks very well. Moreover, few of them can deal with DoS attacks simultaneous...

clustering is an effective approach for managing nodes in wireless sensor network (wsn). a new method of clustering mechanism with using binary gravitational search algorithm (bgsa) in wsn, is proposed in this paper to improve the energy consumption of the sensor nodes.reducing the energy consumption of sensors in wsnsis the objective of this paper that is through selecting thesub optimum senso...

WirelessHART is the most widely applied standard in wireless sensor networks nowadays. However, it does not provide any dynamic routing mechanism, which is important for the reliability and robustness of the wireless network applications. In this paper, a collection tree protocol based, dynamic routing mechanism was proposed for WirelessHART network. The dynamic routing mechanism was evaluated ...

Wireless sensor networks are the most challenging networks for communication because of its resource constrained nature and the dynamical nature of network topographic anatomy. A lot of research is being going on in the diverse parts of the world for optimum utilization of communication resources in these special types of ad hoc networks. The utility and application domain of sensor networks ra...

Wireless sensor networks (WSNs), consisting of autonomous sensor nodes, have emerged as ubiquitous networks that span diverse application domains (e.g., health care, logistics, defense) each with varying application requirements (e.g., lifetime, throughput, reliability). Typically, sensor-based platforms possess tunable parameters (e.g., processor voltage, processor frequency, sensing frequency...

Next generation network will consist of different types of wireless networks like WSN, Wi-Fi, WiMAX, UMTS, LTE and etc. Wireless Sensor Network (WSN) finds unique and special application as compared to the said networks because sensors are deployed in a very secret, awkward and hostile environment like battle field etc. Various wireless sensor nodes are interconnected and form a Wireless Sensor...

Wireless sensor networks can effectively collect and transmit sensor data, and provide users with a wealth of information. It has broad application prospects in the military, civil and industrial production and so on. Then, it has become one of the hot spots in the current research field. However, compared with other communication networks, wireless sensor networks have some disadvantages, such...

Due to the rapid development of wireless charging technology, the recharging issue in wireless rechargeable sensor network (WRSN) has been a popular research problem in the past few years. The weakness of previous work is that charging route planning is not reasonable. In this work, a dynamic optimal scheduling scheme aiming to maximize the vacation time ratio of a single mobile changer for WRS...
