Research on wireless sensor networks (WSNs) has received tremendous attention in the past few years due to their potential applications and advances in the VLSI design. In WSNs with tiny sensors, mobility of a sink may provide an energy efficient way for data dissemination. Having a mobile sink in WSN, however, creates new challenges to routing and sensor distribution modeling in the network. I...

At present, many researchers concentrate on the researches of sink mobility and propose a lot of efficient data harvesting algorithms for wireless sensor networks (WSNs). In general, these algorithms mainly formulate their ideas in two ways, namely path-controllable and path-constrained sink mobility. In most application scenarios of WSNs, mobile sink is path-constrained and a big challenge of ...

Mobile sink node properly used in routing protocols can improve network performance. Thus we investigate the state-of-the-art mobile sink based query-based and location-based routing protocols. The latter strategy can be further classified into backbone-based and rendezvous-based routing protocols. In this paper, we first describe the main principles of the most representative routing strategie...

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...

Measurement losses adversely affect the performance of target tracking. The sensor network's life span depends on how efficiently the sensor nodes consume energy. In this paper, we focus on minimizing the total energy consumed by the sensor nodes whilst avoiding measurement losses. Since transmitting data over a long distance consumes a significant amount of energy, a mobile sink node collects ...

Wireless sensor network is commonly used to monitor certain region and to collect data for several applications. Normally, in wireless sensor network, data are routed in a multi-hop fashion towards a static sink. In this scenario, nodes closer to the sink become heavily involved in packet forwarding and their battery power is exhausted quickly. In this paper, an Infrastructure based Data Gather...

Information gathering is among issues continually obtaining consideration in zone of remote sensor systems (WSNs). There is a reliable increment in examination coordinated on additions of applying versatile components (MEs) to gather information from sensors, particularly those situated to power issues. Two winning systems used to gather information in sensor systems. Main methodology requires ...

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 ...

A crucial issue for data collection in wireless sensor networks is that the energy consumption of the sensor nodes placed near the sink is very high. This is because the sensors placed near the sink have to forward the data to the sink on behalf of others resulting in the depletion of energy quickly, which will lead to network partitioning and limitation in the network lifetime. In order to sol...

This paper introduces algorithms for target tracking in wireless sensor networks (WSNs) that enable reduction of data communication cost. The objective of the considered problem is to control movement of a mobile sink which has to reach a moving target in the shortest possible time. Consumption of the WSN energy resources is reduced by transferring only necessary data readings (target positions...
