Due to non inheritable restriction of sensors, there is always a vital issue on the way to utilize restricted energy effectively. In the proposed work we have focused on the Energy Consumption in WSN Using Mobile Sink and Hierarchal Clustering. There is concept of bringing mobile sinks to sensing field to save energy of cluster heads while sending data to mobile sinks instead of fixed sink on b...

It encompasses the use of mobile telecommunication and multimedia technologies integrated within mobile and wireless health care delivery systems. BASNmHealth system deploys different sensors and actuators to ...

Underwater wireless sensor networks consist of a certain number of sensors and vehicles that interact to collect data and perform collaborative tasks. The sensor network consists of static and mobile underwater sensor nodes. The nodes communicate point-to-point using a novel high-speed optical communication system integrated into the TinyOS stack or other small operating system, and they broadc...

The advances in mobile robotics allow us today to add the mobility concept into many different classes of Wireless Sensor Networks. The deployment of mobile sensors is possible and useful in many application scenarios, ranging from the environmental monitoring and public safety applications, to the industry, healthcare and military applications. Two topics are elaborated in this thesis: network...

In order to reduce the signal holes in wireless sensor networks, we proposed a sensor deployment density-aware signal hole repair strategy of mobile crowd network. On the one hand, based on the multi-dimensional connected graph, the density continuous jitter problem of the sensor network is solved effectively. Sensor density prediction method improves the efficiency of random deployment of sens...

A Hybrid Wireless Sensor network (HWSN) with static and mobile nodes is considered. Static sensors monitor the environment and report events occurring in the sensing field. Mobile sensors are then dispatched to visit these event locations to conduct more advanced analysis. Mobile sensor will collect the information about the event and in turn will send it to the base station. As WSN is vulnerab...

WSNs-Wireless Sensor Networks comprises of small nodes with computation, sensing and wireless communications capabilities. Energy awareness is an essential design for WSNs and hence data broadcasting protocols, routing and power management isspecially designed to meet this requirement. However, the focus is mainly on the routing protocols which differ depending on the network design and applica...

A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption. Although different methods have been successfully proposed by researchers to tackle...
