A Semantic-Driven Cache Management Approach for Mobile Applications [chapter]

Guiyi Wei, Jun Yu, Hanxiao Shi, Yun Ling
2006 Lecture Notes in Computer Science  
The semantic caching is particularlly attractive in a mobile business environment, due to its content-based reasoning ability and semantic locality.  ...  It establishes an semantic associated rule-base according to the knowledge of application domains, makes use of the semantic locality for data prefetching, and adopts a Two-level LRU algorithm for cache  ...  The cache of the mobile terminal is divided into a basic cache and a prefetched data set. The basic cache accommodates the data produced with the temporal locality principle.  ...

Using semantic caching to manage location dependent data in mobile computing

Qun Ren, Margaret H. Dunham
2000 Proceedings of the 6th annual international conference on Mobile computing and networking - MobiCom '00  
We first develop a mobility model to represent the moving behaviors of mobile users and formally define location dependent queries.  ...  In this paper, a semantic caching scheme is used to access location dependent data in mobile computing.  ...  Hence, the status of a mobile unit is modeled to be always associated with a particular timestamp.  ...

Semantic Prefetching Strategy to Manage Location Dependent Data in Mobile Information Systems

Sang-Won Kang, MoonBae Song, KwangJin Park, Chong-Sun Hwang
2005 Mobile Information Systems  
Our performance results show that this method is superior when compared with traditional semantic cache schemes.  ...  A query result can also be transferred to a local device. Through our proposed semantic prefetching scheme, we make it possible to send data to mobile clients in advance.  ...  In Section 3, we provide a model suitable for mobile information systems. Section 4 represents a proposed semantic prefetching technique and deals with query processing and cache management schemes.  ...

Semantic caching for pervasive grids

Laurent d'Orazio, Mamadou Kaba Traoré
2009 Proceedings of the 2009 International Database Engineering & Applications Symposium on - IDEAS '09  
In this paper, we propose a caching approach enabling to improve querying on pervasive grids. Our proposal, called semantic pervasive dual cache, follows a semantics oriented approach.  ...  We have validated semantic pervasive dual cache using analytic models and simulations. Results obtained show that our approach is quite promising.  ...  Models under evaluation Three different models are considered: • BasicModel: a system where mobile clients are not associated with a cache, whereas they consider a proxy dual cache whose task is to treat  ...

A New Semantic Cache Management Method in Mobile Databases

Shengfei Shi, Jianzhong Li, Chaokun Wang
2005 Journal of Computer Science  
In mobile database systems, caching is a crucial way to improve the performance because a new query can be partially answered locally when the client is continuously moving around.  ...  Moreover, although many improved semantic caching strategies for mobile computing application have been proposed in recent years, few papers discussed semantic cache coherence control, which is very important  ...  Compared with the traditional caching strategies, such as page caching and tuple caching, semantic caching maintains a semantic description of the data in cache.  ...

On the Content Predictability of Cooperative Image Caching in Ad Hoc Networks

Bo Yang, A.R. Hurson, Yu Jiao
2006 7th International Conference on Mobile Data Management (MDM'06)  
Caching is a widely used approach in mobile environments to improve system performance and keep track of replications.  ...  In this paper, we present a semantic-aware caching scheme (SAIC) for image databases in ad hoc networks.  ...  The local cache of a mobile node n i is a set of cache entries -each entry indicates one or multiple remote nodes in the network.  ...

On Semantic Caching and Query Scheduling for Mobile Nearest-Neighbor Search

Baihua Zheng, Wang-Chien Lee, Dik Lun Lee
2004 Wireless networks  
An index based on Voronoi Diagram is used in the server to support such a search, while a semantic cache is proposed to enhance the access e ciency of the service.  ...  Cache replacement policies tailored for the proposed semantic cache are examined.  ...  For a mobile client w i t h a semantic cache, it issues a query to the server just like a client with a traditional cache, if the answer is not available in cache.  ...

Location dependent query proxy

Xing Gao, Ali R. Hurson
2005 Proceedings of the 2005 ACM symposium on Applied computing - SAC '05  
Applying the concept of caching to this class of queries provides a means of efficiently processing queries exhibiting both semantic similarity and spatial locality.  ...  In a mobile environment, in many application domains, the result of queries often depends on the client's location.  ...  clients have no local cache.  ...

Considering a Semantic Prefetching Scheme for Cache Management in Location-Based Services [chapter]

Sang-Won Kang, SeokJin Im, Jongwan Kim, SeongHoon Lee, Chong-Sun Hwang
2006 Lecture Notes in Computer Science  
The mobile client maintains the semantic information in a local repository (i.e., a cache), which means it can obtain the query results from the repository without having to send a request to the server  ...  Range queries can get their results from the cache, with only a few requests to the server, regardless of mobility and query patterns.  ...  With these query patterns, users were assumed to move according to their own mobility characteristic. In our simulation, we used a random walk model with a mobility probability p over the 2500 SPAs.  ...

Content-Based Retrieval in Peer-to-Peer Networks Using Cooperative Caching

Bo Yang, Manohar Mareboyana
2011 Proceedings of the 7th International Conference on Collaborative Computing: Networking, Applications and Worksharing  
In this paper, we present a logic-based model for representing the semantics of complex multimedia data objects.  ...  Devising a uniform paradigm for the representation of multimedia data contents in distributed systems in the presence of heterogeneity, distribution, and semantic gap is a difficult task.  ...  The better performance of SAIC in contrast with CachePath stems from its capability of exploiting the semantic locality with vicinity constraints.  ...

Semantic Caching for Multiresolution Spatial Query Processing in Mobile Environments [chapter]

Sai Sun, Xiaofang Zhou, Heng Tao Shen
2005 Lecture Notes in Computer Science  
Based on the study of the characteristics of multiresolution spatial data (MSD) and multiresolution spatial query, we propose a new semantic caching model called Multiresolution Semantic Caching (MSC)  ...  Our extensive experiments on a very large and complex real spatial database show that MSC outperforms the traditional semantic caching models significantly.  ...  In [6] , a proactive caching model, which caches the result objects as well as their Rtree index nodes, was proposed to improve the utility of local caches.  ...
