In visible light communication (VLC) network, which can provide high data rate information transmission, the multiple users will get access to network according to the carrier sense multiple access with collision avoidance (CSMA/CA) mechanism specified by IEEE 802.15.7 standard. In this paper, we propose to improve the channel access mechanism by increasing the channel utilization efficiency and achieving...
This paper addresses network-based consensus problem of nonlinear multi-agent systems under Markovian switching topologies. Considering the effect of network-induced delay and Markovian switching topologies, a new network-based switching consensus control protocol is proposed, with which each agent can be remotely operated through a communication network. Under this protocol, the consensus problem...
Wearable sensors are designed to monitor the individual user's activities or the social behaviors within a group. Due to the nature of their applications, the wireless transmission of the sensory data are subject to extremely stringent energy constraints. Also, due to user mobility, the network topology is frequently changing. Therefore, the design of efficient communication protocols for wearable...
