Recently sink mobility has been exploited in numerous schemes to prolong the lifetime of wireless sensor networks (WSNs). Contrary to traditional WSNs where sensory data from sensor field is ultimately sent to a static sink, mobile sink-based approaches alleviate energy-holes issues thereby facilitating balanced energy consumption among nodes. In mobility scenarios, nodes need to keep track of ...

In recent years, much study has been made by applying the non-extensive statistics (NES) to various non-extensive systems where the entropy and/or energy are not necessarily proportional to the number of their constituent subsystems. The non-extensivity may be realized in many systems such as physical, chemical and biological ones, and also in small-scale systems. After briefly reviewing the re...

In WSN, data aggregation is an important process for reducing the energy consumption. We can reduce energy consumption by using the efficient technique for data aggregation. Also, achieving the reliability and robustness of transferring data is one of the major issues and challenges. in order to produce both reliability and energy efficiency, in this paper we propose to design a Mobile Sink for...

Energy consumption phenomenon has always been noticed in sink-based wireless sensor networks. This paper explored an energy efficient routing protocol with a mobile sink based on the shortest path data transmission mode. According to the position of the sink node and the common nodes' ID in the network, we can calculate the coordinate value of each node in the wireless sensor network. By compar...

In this paper, we study a problem of passive control of friction-induced vibrations due to mode coupling instability in breaking systems. To achieve that, the well-known two degrees of freedom Hultèn’s model, which reproduces the typical dynamic behavior of friction systems, is coupled to two ungrounded Nonlinear Energy Sinks (NES). The NES involves an essential cubic restoring force and a line...

In wireless sensor network (WSN), data gathering causes more energy consumption. Also most of the existing literature work on data gathering process considers only distance and node density and skips reliability criteria. Hence in order to offer both reliability and energy efficiency, in this paper, we propose to design a Mobile Sink Based Reliable and Energy Efficient Data Gathering technique ...

Wireless sensor networks basically consist of low cost sensor nodes which collect data from environment and relay them to a sink, where they will be subsequently processed. Since wireless nodes are severely power-constrained, the major concern is how to conserve the nodes' energy so that network lifetime can be extended significantly. Employing one static sink can rapidly exhaust the energy of ...

Due to constrained energy source in wireless sensor nodes energy awareness is an essential design issue in wireless sensor networks.Attention must be paid torouting protocols in these networks since they might differ depending uponthe application and network architecture underneath.In this paper,we proposeda Sink Location-oriented Data Dissemination using Grid in Wireless Sensor Networks (SLDD)...
