The task of routing streaming data in a sensor network is made arduous by the resource constraints imposed on each node. The control overhead of a routing protocol has to be minimized in order to preserve limited resources at the node. Furthermore, it is widely expected that the gateway of the sensor network will not be static in many application scenarios, but will be moving around the network...

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 ...

In this paper we propose a new routing protocol called virtual sink rotation (VSR) routing for large-scale sensor networks. VSR can efficiently handle a large number of sources as well as a large number of sinks with potential mobility. Each sensor node is not required to know the global network topology nor the location awareness. The main ideas underlying the VSR are two folds. First, to alle...

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)...

We address the problem of maximizing the lifetime in a wireless sensor network with energy-constrained sensor nodes and mobile data collection points (sinks). Information generated by the monitoring sensors needs to be routed efficiently to the location where the sink is currently located across multiple hops with different transmission energy requirements. We exploit the capability of the sink...

The major issues in wireless sensor networks are data collection from sensors nodes. 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 challenges. Hence in order to produce both reliabi...

Sink Mobility is a imminent growth sensing environments promotes the increasing number of event based, sensor network applications including rescue missions, intrusion detection and smart buildings. Most of critical challenges supporting quality of service is effective in distributed congestion avoidance in these setting. In this paper the problem of traffic management in the sensor networks wi...

The main objective of this project is big data gathering using clustering. Big data is an all-encompassing term for any collection of data sets so large and complex that it becomes difficult to process them using traditional data processing applications. This project proposes big data gathering in distributed sensor network. Data gathering is very complex. This project proposed the new clusteri...

Data dissemination is the most significant task in a Wireless Sensor Network (WSN). From the bootstrapping stage to the full functioning stage, a WSN must disseminate data in various patterns like from the sink to node, from node to sink, from node to node, or the like. This is what a WSN is deployed for. Hence, this issue comes with various data routing models and often there are different typ...

Mobile sinks are proposed to save sensor energy spent for multihop communication in transferring data to a base station (sink) in Wireless Sensor Networks. Due to relative low speed of mobile sinks, these approaches are mostly suitable for delay-tolerant applications. In this paper, we study the design of a query scheduling algorithm for query-based data gathering applications using mobile sink...
