Wireless sensor networks (WSNs) are widely applied in various industrial applications. In this paper, we present an efficient data gathering scheme that guarantees the Quality of Service and optimizes the following network performance metrics as well as the end-to-end reliability in WSNs: 1) minimum total energy consumption; 2) minimum unit data transmitting energy consumption; and 3) maximum utilization...
Energy consumption and performance are always major considerations in microprocessor optimization. However, mostly, saving energy causes performance decrement. Based on the previous energy saving research on tag reduction for low power Chip Multiprocessor (CMP), we proposed an improved approach to balance energy and performance by introducing an affiliation degree. To our best knowledge, this is the...
WANET (wireless ad-hoc network) is expected to be deployed in a wide range of civil and military applications. The communicating nodes in these networks might be distributed randomly and are assumed to have packet-forwarding capability in order to communicate with each other over a shared and limited radio channel. Building such networks usually poses a significant technical challenge because energy...
With the great progress of technologies, computers are embedded into everywhere to make our daily life convenient, efficient and comfortable. Ubiquitous society became so real for us with this fast development. However, how to integrate distributed resources existed among heterogeneous devices to build pervasive applications that can constantly adapt to the highly dynamic computing environment is...
