The wireless communication technologies, such as wireless sensor network, can bring great economic benefits to industrial plants. But the open channel and multi-hop network topology will influence its real-time and reliable performance. Funneling effect is a kind of congestion caused by the wireless hop-by-hop and many-to-one networks. IEEE802.15.4 is a wireless personal area network standard that...
This paper presents a novel hierarchical and grid based reconfigurable optical-wireless network (GROW-Net) architecture. GROW-Net supports scalable and flexible integration of a large scale wireless mesh network in a municipal environment. Under the GROW-Net architecture, a joint evolution strategy is proposed to allow graceful upgrades in both optical backbone and wireless mesh network. To alleviate...
Wireless body area networks (WBANs) enable placement of tiny biomedical sensors on or inside the human body to monitor vital body signs. The IEEE 802.15.6 task group is developing a standard to optimize WBAN performance by defining the physical layer (PHY) and media access control (MAC) layer specifications. In this paper an energy efficient MAC protocol (BodyMAC) is proposed. It uses flexible bandwidth...
Due to lack of inexpensive infrastructure rural communities suffer from inadequate Internet access, which is gradually widening the digital division between town and countryside, resulting in degrading both social communication and business advancements. In order to examine the feasibility of constructing a community mesh network using partial off-the-shelf hardware and software components, our research...
