In this paper, polling based mobile data gathering and the priority based data storage algorithm for wireless sensor networks (WSN) is proposed. Initially, the centralized algorithm places the polling points (PPs) on the shortest path. These polling points (PP) buffer locally aggregated data and upload the data to the mobile data collector when it arrives. Then, priority based data storage modu...

Introduction The dissertation work is focused on devices, methods, and algorithms for gathering, analysis, and processing of sensor information in mobile robotics. Recently, this field has gained in importance, since mobile robots expose increasing variety of applications. Despite the achieved results in the field, there are still some unsolved problems: 1/ The price of some range-finders, such...

Recent research has shown that using mobile robots as mobile nodes to gather and carry data in WSNs can effectively reduce the data relay hop count and improve the lifetime of the WSNs. But because of the low speed feature of the mobile robot, a greater time delay has been produced in the process of gathering data in WSNs with mobile robot. In order to make a balance between the lifetime of WSN...

In this paper, we propose the mobility of a sink in improved energy efficient PEGASIS-based protocol (IEEPB) to advance the network lifetime of Wireless Sensor Networks (WSNs). The multi-head chain, multi-chain concept and the sink mobility affects largely in enhancing the network lifetime of wireless sensors. Thus, we recommend Mobile sink improved energy-efficient PEGASIS-based routing protoc...

This paper describes the progress of a project to locate, recognize and manipulate objects using information from whisker sensors. Object surface information is gathered by measuring the angle of deflection of a rigid whisker as it slides over the object surface. In order to successfully reconstruct the surface shape of an object, the whisker tip has to be in contact with the object. Ambiguous ...

We research the topological control of the combination of the clustering hierarchical structure and sleep scheduling mechanism. Firstly, present a inner-cluster node scheduling algorithm solution of inner-cluster connectivity coverage problem, which can meet user’s expected coverage,avoiding the influence of mobile node location. Based on coverage analysis theory, deducts smallest mobile nodes ...

Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. Gathering sensed information in an energy efficient manner is critical to operate the sensor network for a long period of time. Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful infor...
