The RFID (Radio Frequency Identification) localization technology has become one of the most developed technologies owing to its low cost, full-fledged application and flexible deployment. However, current RFID localization system cannot achieve the task of precise and highly accurate object localization due to the limitations of localization algorithm.(More)
In ubiquitous wireless environment, mobile devices need a more resilient and convenient network communication software. Mobile Ad Hoc Network (MANET) routing protocols are favored in ubiquitous environments due to its self-organization and self-reconstruction characteristics. Routing protocols however, especially the MANET routing protocols, are suffering(More)
In object tracking wireless sensor networks, communication overheads affect the accuracy of tracking localization seriously. Existing seminar works suffer from lacking of adaptively on various accuracy requirements, which lead to large amount of network traf¿c. In this paper, we propose a coordination mechanism based on joint mobility prediction method(More)
In this paper, we study the performance evaluation method applying Principle Component Analysis (PCA) theory. Due to the self-organizing and distributed character, each metric has its representative character evaluation method. Metrics while considering various network scenarios reflect different aspects of routing protocol efficiency in mobile ad hoc(More)
Identifying heavy hitters is essential for network monitoring, management, charging and etc. Existing methods in the literature have some limitations. How to reduce the memory consumption effectively without compromising identification accuracy is still challenging. In this paper, an adaptive method combining sampling and data streaming counting is(More)
In large-scale object tracking wireless sensor networks, multiple mobile nodes will bring large amount of communication overheads in maintaining the accuracy of localization tracking, which would possibly affect the collection and dissemination of the tracking data, seriously. Existing seminar works purely focus on achieving optimal tracking accuracy and(More)
In dynamic wireless networks, effective modeling on link behavior would lead the network protocol design towards a predictive and reasonable way. Emerging mobile ad hoc network (MANET), however, is of self-organizing and infrastructureless paradigm, where topology dynamics are highly related to many complicated parameters, such as node density, mobility(More)
