Wireless mesh networks
Abstract
Wireless telemedicine using GSM and GPRS technologies can only provide low bandwidth connections, which makes it difficult to transmit images and video. Satellite or 3G wireless transmission provides greater bandwidth, but the running costs are high. Wireless networks (WLANs) appear promising, since they can supply high bandwidth at low cost. However, the WLAN technology has limitations, such as coverage. A new wireless networking technology named the wireless mesh network (WMN) overcomes some of the limitations of the WLAN. A WMN combines the characteristics of both a WLAN and ad hoc networks, thus forming an intelligent, large scale and broadband wireless network. These features are attractive for telemedicine and telecare because of the ability to provide data, voice and video communications over a large area. One successful wireless telemedicine project which uses wireless mesh technology is the Emergency Room Link (ER-LINK) in Tucson, Arizona, USA. There are three key characteristics of a WMN: self-o...

This paper proposes a mobile patient monitoring system, which integrates current personal digital assistant (PDA) technology and wireless local area network (WLAN) technology. At the patient's location, a wireless PDA-based monitor is used to acquire continuously the patient's vital signs, including heart rate, three-lead electrocardiography, and SpO/sub 2/. Through the WLAN, the patient's biosignals can be transmitted in real-time to a remote central management unit, and authorized medical staf...

Two different prototype mobile telemedicine systems were constructed for use in the emergency room. They could transmit physiological signals as well as video pictures and sound. One device, the mobile emergency bed (MEB), was powered by battery and had a wireless connection to the local-area network (LAN). For the other, the mobile emergency server (MES), a patient monitor, video-camera and microphone were connected by a radio-frequency link to a server. A functional evaluation and a clinical e...

p at a disaster scene can greatly benefit from technologies that continuously moniatients at a disaster scene can greatly benefit from technologies that continuously monitor their vital status and track their location until they are admitted to a hospital. We have designed and developed a real-time patient monitoring system that integrates vital signs sensors, location sensors, ad hoc networking, electronic patient records, and web portal technology to allow remote monitoring of patient status. ...

With the increasing demand on high quality wireless broadband access service, the traditional access technologies become inadequate. As a new and promising next generation network, wireless mesh network draws researchers’ attention by its advantages of large coverage, low deployment cost, convenient access and so on. In this paper, we research on the performance of channel allocation scheme in IEEE 802.11s WMN. The property of the traditional fixed assignment algorithm and the mesh interference ...

2 Abstract:In recent years, wireless mesh networks have become more popular than ever. They are now called as last mile internet connectivity. WMN has the advantage of robust fault tolerance. Even if some of the mesh nodes are incapable, there exist many other alternative nodes to serve relay. In addition, multi-hop of WMN can not only spread coverage but also save both cabling cost and human resource. A common problem in WMN is the performance degradation with multiple hops. This is due to the ...

Wireless Sensor Networks are becoming popular as a means of collecting data by military organisations, public utilities, motor vehicle manufacturers and security firms. Unfortunately, the devices on such networks are often insecure by default, which creates problems in terms of the confidentiality and integrity of data transmitted across such networks. This paper discusses attacks that were successful on a simple network consisting of nodes using the ZigBee protocol stack and proposes defences t...

We study the problem of wireless groupcast routing when multiple transmission methods are available. The paper is inspired by GroupCast with Retries (GCR) methods appeared in IEEE 802.11aa in 2012. The paper contributes with comparative analysis of GCR methods in a wireless multihop network from the groupcast routing perspective. It also addresses the issue of possible benefit for a routing protocol to account for this palette of transmission methods.

Wireless Mesh Networks(WMNs) are emerging and low-cost next generation wireless networks. WMNs are able to provide communication for all types of networks with its backbone composed of low mobile or stationary Mesh Routers(MR). In WMNs, most of the traffic is generated by either Mobile Clients(MC) or Mesh Points(MP). MRs and MCs are two different mobile nodes in WMNs with different resources. Due to low mobility at MR level, proactive scenario performs well and proactive approach effectively uti...
