The precise spatio-temporal position data of vehicles is useful for most studies, such as wireless link lifetime and node degree in vehicular ad hoc networks. However, due to the system errors and random errors, the existing Global Positioning System (GPS) only provides the positional accuracy about 10m or even worse. In this paper, to address the issue of positional accuracy, a Clustering and Approximating...
Resource management is a crucial task in vehicular ad hoc networks (VANETs) due to the existence of various resources, such as text, audio and video. However, the highly dynamic network feature and the limited memory of the local server pose challenges to resource management, which not only lead to the failure of resource presentations to users, but the transmission of the invalid fragment data would...
Compared with hardware-based methods, software-based methods which need not additional hardware costs are regarded as efficient methods to tolerate soft errors. Software-based methods which are implemented by software protection have performance sacrifice. This paper proposes a new configurable approach whose purpose is to balance system reliability and performance, to tolerate soft errors via partial...
