The traditional wireless sensor networks (WSNs) fixed the sink node in a certain place has a serious hotspot problem. The sensors closer to the sink node usually required forwarding a large amount of traffic for sensors farther from the sink node. Hotspot problem causes the nodes near the hotspot sensor node consuming much more energy than the other nodes, which seriously shortens the lifetime ...

We study the problem of fast and energy-efficient data collection of sensory data using a mobile sink, in wireless sensor networks in which both the sensors and the sink move. Motivated by relevant applications, we focus on dynamic sensory mobility and heterogeneous sensor placement. Our approach basically suggests to exploit the sensor motion to adaptively propagate information based on local ...

The lifetime of wireless sensor networks can be improved by imposing low duty cycle, but doing so could not solve unbalanced energy consumption and will increase transmission latency. To avoid this, this paper gives a new method to collect data by mobile sink. The proper data collection route is selected according to the sink speed and buffer size of the sensors. The sensors only wake up when t...

In wireless sensor network, abusing or mishandling the sink mobility or portability has been considered as a better technique to modify the center points or hubs vitality dispersal. Disregarding its different great circumstances, the data disseminating to the compact sink is a trying task for the benefit obliged sensor center points as a result of the component framework topology made by the si...

In this paper, we propose an effective mobile sensor control method, named DATFM (Data Acquisition and Transmission with Fixed and Mobile node) for sparse sensor networks. DATFM uses two types of sensor nodes, fixed node and mobile node. The data acquired by nodes are accumulated on a fixed node before being transferred to the sink node. In addition, DATFM transfers the accumulated data efficie...

This paper summarizes an effort to evaluate the usability of a mobile sink for identifying the boundary of a wireless sensor network. In order to achieve the desired task we transform the problem of boundary identification into one of edge node identification. The algorithm designed is based on a mobile sink equipped with a directional antenna, which identifies the edge nodes and connects them ...

Uneven energy consumption is an inherent problem in wireless sensor networks characterized by multihop routing and many-to-one traffic pattern. Such unbalanced energy dissipation can significantly reduce network lifetime. In this paper, we study the problem of prolonging network lifetime in large-scale wireless sensor networks where a mobile sink gathers data periodically along the predefined p...

Wireless Sensor Networks is a fast leading technology which has showed up many opportunities in the field of data reporting and monitoring. It has a collection of sensor nodes which can report data to the base station. It increases energy consumption and traffic. So to avoid network traffic and to prolong network lifetime clustering scheme is used. Mobile sinks can easily move to the deployed a...
