Sink mobility has been widely used to reduce the energy consumption of sensor nodes, which can prolong the lifetime of nodes in wireless sensor networks (WSNs). Researchers found that sink mobility can improve the stability, throughput and lifetime of the very large-scale WSNs. However, sink mobility also causes issues such as data latency and communication overhead. With these properties sink ...

Maximizing the lifetime of energy constrained wireless sensor networks is a very challenging issue. It has been demonstrated that the use of a mobile sink can significantly increase the network lifetime by balancing the load among nodes. However, in existing solutions, nodes either send their data through multihop towards the sink or store the data until the sink comes at the node’s vicinity, w...

With the rapid development of Internet of Things (IoT), more and more static and mobile sensors are being deployed for sensing and tracking environmental phenomena, such as fire, oil spills and air pollution. As these sensors are usually battery-powered, energy-efficient algorithms are required to extend the sensors’ lifetime. Moreover, forwarding sensed data towards a static sink causes quick ...

Wireless sensor network can be used in military application for monitoring militant activities like tracking enemies, force protection and monitoring the vital signs of the soldiers who are in a battlefield. Wireless sensor network has set of distributed sensor nodes which are connected to each other. These sensor nodes are low powered, low cost, small in size with limited amount of battery sup...

In recent years there has been an increased focus on the use of sensor networks to sense and measure the environment. This leads to a wide variety of theoretical and practical issues on appropriate protocols for data sensing and transfer. Recent work shows sink mobility can improve the energy efficiency in wireless sensor networks (WSNs). However, data delivery latency often increases due to th...

More and more researchers concentrate their attention on energy efficient usage and lifetime of Wireless Sensor Networks (WSNs). One of the complications impacting network lifetime is hotspot issue which can be solved by emerging Mobile Sink Wireless Sensor Networks (MSWSNs). In this paper, we propose circle-based data dissemination (CBDD) algorithm which supposes that sensor nodes are symmetri...

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 ...

Traffic patterns in wireless sensor networks (WSNs) usually follow a many-to-one model. Sensor nodes close to static sinks will deplete their limited energy more rapidly than other sensors, since they will have more data to forward during multihop transmission. This will cause network partition, isolated nodes and much shortened network lifetime. Thus, how to balance energy consumption for sens...
