Exploring Application-Level Semantics for Data Compression
1Application-Level.doc (Size: 32 KB / Downloads: 28) Abstract Natural phenomena show that many creatures form large social groups and move in regular patterns. However, previous works focus on finding the movement patterns of each single object or all objects. In this paper, we first propose an efficient distributed mining algorithm to jointly identify a group of moving objects and discover their movement patterns in wireless sensor networks. Afterward, we propose a compression algorithm, called 2P2D, which exploits the obtained group movement patterns to reduce the amount of delivered data. The compression algorithm includes a sequence merge and an entropy reduction phases. In the sequence merge phase, we propose a Merge algorithm to merge and compress the location data of a group of moving objects. In the entropy reduction phase, we formulate a Hit Item Replacement (HIR) problem and propose a Replace algorithm that obtains the optimal solution. Moreover, we devise three replacement rules and derive the maximum compression ratio. The experimental results show that the proposed compression algorithm leverages the group movement patterns to reduce the amount of delivered data effectively and efficiently. Existing System Discovering the group movement patterns is more difficult than finding the patterns of a single object or all objects, because we need to jointly identify a group of objects and discover their aggregated group movement patterns. The constrained resource of WSNs should also be considered in approaching the moving object clustering problem. However, few of existing approaches consider these issues simultaneously. On the one hand, the temporal-and-spatial correlations in the movements of moving objects are modeled as sequential patterns in data mining to discover the frequent movement patterns . Proposed System: We have proposed a clustering algorithm to find the group relationships for query and data aggregation efficiency. The differences of and this work are as follows: First, since the clustering algorithm itself is a centralized algorithm, in this work, we further consider systematically combining multiple local clustering results into a consensus to improve the clustering quality and for use in the update-based tracking network. Second, when a delay is tolerant in the tracking application, a new data management approach is required to offer transmission efficiency, which also motivates this study. We thus define the problem of compressing the location data of a group of moving objects as the group data compression problem. We first introduce our distributed mining algorithm to approach the moving object clustering problem and discover group movement patterns. Then, based on the discovered group movement patterns, we propose a novel compression algorithm to tackle the group data compression problem. Module Description: Input data We have found that many creatures, such as elephants, zebra, whales, and birds, form large social groups when migrating to find food, or for breeding or wintering. These characteristics indicate that the trajectory data of multiple objects may be correlated for biological applications. Moreover, some research domains, such as the study of animal’s social behavior and wildlife migration, are more concerned with the movement patterns of groups of animals. These details are given as an input data. Apply mining technique To approach the moving object clustering problem, we propose an efficient distributed mining algorithm to minimize the number of groups such that members in each of the discovered groups are highly related by their movement patterns. Apply compression technique We propose a novel compression algorithm to compress the location data of a group of moving objects with or without loss of information. We formulate the HIR problem to minimize the entropy of location data and explore the Shannon’s theorem to solve the HIR problem. We also prove that the proposed compression algorithm obtains the optimal solution of the HIR problem efficiently. View result View the data result that the result contains the mined and compressed data. We exploit the characteristics of group movements to discover the information about groups of moving objects in tracking applications. We propose a distributed mining algorithm, which consists of a local GMPMine algorithm and a CE algorithm, to discover group movement patterns. With the discovered information, we devise the 2P2D algorithm, which comprises a sequence merge phase and an entropy reduction phase. In the sequence merge phase, we propose the Merge algorithm to merge the location sequences of a group of moving objects with the goal of reducing the overall sequence length. In the entropy reduction phase, we formulate the HIR problem and propose a Replace algorithm to tackle the HIR problem. In addition, we devise and prove three replacement rules, with which the Replace algorithm obtains the optimal solution of HIR efficiently.

The UML represents a collection of best engineering practices that have proven successful in the modeling of large and complex systems. The UML is a very important part of developing objects oriented software and the software development process. The UML uses mostly graphical notations to express the design of software projects. Using the UML helps project teams communicate, explore potential designs, and validate the architectural design of the software. Goals of UML: Portent is to define some general purpose modeling language which all modelers can use and also it needs to be made simple to understand and use. UML diagrams are not only made for developers but also for business users, common people and anybody interested to understand the system. The system can be a software or non software. So it must be clear that UML is not a development method rather it accompanies with processes to make a successful system. At the conclusion the goal of UML can be defined as a simple modeling mechanism to model all possible practical systems in today’s complex environment. Data Flow Diagrams: A Data flow diagram is graphical tool to describe and analyze movement of data through a system. These are the central tool and the basis from which the other components are developed. The transformation of data from input to output, through processed, may be described logically and independently of physical components associated with the system. These are known as the logical data flow diagrams. The physical data flow diagrams show the actual implements and movements of the data between people, departments and work stations. A DFD is also known as “bubble chart” has the purpose of clarifying system requirements and identifying major transformations that will become programs in system design. So it is the starting point of the design to the lowest level of the details.

UNIFIED MODELING LANGUAGE DIAGRAMS The Unified Modeling Language (UML) is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. Usecase Diagram A use case diagram shows a set of use cases and actors (a special kind of class) and their relationships. Use case diagram address the static use case view of a system. Activity Diagram Activity diagrams may stand alone to visualize, specify, construct and document the dynamics of a society of objects or they may be used to model the flow of control of an operation.
