A Sensor Data Collection Method for Multi-granularity Contour Lines Map Creations on an Overlay Network

Building a Multi-Granularity Sensor Network Using 2-dominating Sets

Granularity in Multi-Method

Multi-method planning is an approach to using a set of different planning methods to simultaneously achieve planner completeness, planning time efficiency, and plan length reduction. Although it has been shown that coordinating a set of methods in a coarse-grained, problem-by-problem manner has the potential for approaching this ideal, such an approach can waste a significant amount of time in ...

Multi-Source Cooperative Data Collection with a Mobile Sink for the Wireless Sensor Network

The multi-source cooperation integrating distributed low-density parity-check codes is investigated to jointly collect data from multiple sensor nodes to the mobile sink in the wireless sensor network. The one-round and two-round cooperative data collection schemes are proposed according to the moving trajectories of the sink node. Specifically, two sparse cooperation models are firstly formed ...

A Multi-Objective Method for Network Reconfiguration (TECHNICAL NOTE)

This paper presents an algorithm based on multi-objective approach for network reconfiguration. Multiple objectives are considered for reduction in the system power loss, deviations of the nodes voltage and transformers loading imbalance, while subject to a radial network structure in which all the loads must be energized and no branch current constraint is violated. These three objectives are ...

Sensor network data analysis at different levels of granularity

The analysis of sensor network data may reveal insights at different levels of granularity. Based on the example of analysing fish movement data in Murray River in Australia, it is shown how the use of different levels of granularity allow the aggregation of otherwise sparse data and find insights into fish movement behaviour. The approach is then conceptually extended to more complex network s...
