In this paper we study the communication reliability of wireless sensor networks (WSN) under a phased-mission framework. Two types of communication phases in WSN are identified: infrastructure communication phase (ICP) and application communication phase (ACP). A complete WSN communication task usually involves one or more ICP and ACP. The difficulties in the reliability analysis of traditional phased-mission...
Wireless links are one of the primary performance-limiting factors in wireless sensor networks (WSNs). In particular, link failures negatively influence the network performance, reliability, and availability in most cases. In WSNs, a link failure might result in the loss of the shortest path between a sensor node and the sink node; thus the data will have to be transmitted via a longer path, leading...
Wireless sensor networks (WSNs) bring significant advantages over traditional communications in today’s applications, such as environmental monitoring, homeland security, and health care. However, harsh and complex environments pose great challenges in the reliability of WSN communications. To achieve reliable wireless communications within WSNs, it is essential to have a reliable routing protocol...
To achieve natural and smooth control of prostheses, Electromyographic (EMG) signals have been investigated for decoding user intent. However, EMG signals can be easily contaminated by diverse disturbances, leading to errors in user intent recognition and threatening the safety of prostheses users. To address this problem, we propose a trust sensor interface (TSI) that contains 2 modules: (1) abnormality...
