Sensor nodes transmit the sensed information to the sink through wireless sensor networks (WSNs). They have limited power, computational capacities and memory. Portable wireless devices are increasing in popularity. Mechanisms that allow information to be efficiently obtained through mobile WSNs are of significant interest. However, a mobile sink introduces many challenges to data dissemination...

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)...

Wireless Sensor Networks (WSNs) are often deployed in hostile environments to detect and collect interested events such as the appearance of a rare animal, which is called event collection system. However, due to the open characteristic of wireless communications, an adversary can detect the location of a source or sink and eventually capture them by eavesdropping on the sensor nodes’ transmiss...

Geographic routing in wireless sensor networks requires sources nodes to be aware of the location information of sinks to send their data. To provide the sink location service, quorum-based schemes have been proposed, which exploit crossing points between a quorum of a sink location announcement (SLA) message from a sink and a quorum of a sink location query (SLQ) message from a source node. Fo...

Mobile sink based data gathering for improving network lifetime in Wireless Sensor Networks (WSNs) has been extensively studied in literature. Mobile sinks are useful in mitigating energy-hole problem that can occur due uneven energy consumption among sensor nodes. However, the approach introduces new challenges during data delivery due to continuous change in the sink location. For efficient d...

This work investigates into the design of sink location propagation in wireless sensor network with mobile sink. In our proposed work, few sensor nodes are assigning a role to propagate the sink location information to the remaining nodes. We refer such nodes as beacon nodes (BNs). We design a distributed algorithm to select BNs. The selection of BNs depends on their sensor node degree. To ensu...

With the advances of more and more mobile sink deployments (e.g., robots and unmanned aerial vehicles), mobile sinks have been demonstrated to play an important role in the prolongation of network lifetime. In this paper, we consider the network lifetime maximization problem for time-sensitive data gathering, which requires sensing data to be sent to the sink as soon as possible, subject to sev...
