Current advances in wireless sensor networks have contributed to the development of multi-hop wireless body sensor networks (WBSNs). These networks, which are primarily comprised of low-power sensor nodes, provide long term health and physiological monitoring of patients without obstructing their normal activities. However, the time-varying nature of(More)
The present paper describes functions and procedures of FUTON Radio Over Fiber Manager to operate with upper (network) and lower (physical) layers used in the transport of the wireless signals between a Central Unit (CU) and Remote Antenna Units. Also, it presents some mechanisms and procedures to be used in case of failures, while enabling end-to-end(More)
1 The concept of Pattern Mining has obtained significant focus in Telecommunications Network Management System (NMS). A big volume of literature has been dedicated to this field and valuable progress was also observed. Both sequential and structured pattern mining techniques were observed to be considered in NMS. In particular NMS logs (Performance and(More)
Failure survivability mechanisms are indispensable in transport networks but their support can demand a significant overprovisioning of network resources. Shared restoration is seen as a mechanism that can help in reducing the amount of extra resources needed, while still providing a reasonable capability to withstand failures. By having all restoration(More)
In order to reduce the costs associated with network planning, this paper presents a tool tailored for Radio over Fibre networks that: determines the location of antennas to cover a Manhattan like scenario considering candidate sites at different heights, for example on top of building or on street lamp posts; defines the number and location of optical(More)
Advancement of communication technologies and business patterns has contributed to the increase of consumer demand and machine-to-machine network traffic. Following this, a steep downward trend in revenue per bit and a slower decay in cost per bit transported is being observed. This poses serious challenge for network operators to correctly choose the(More)
Coherent transmission is becoming pervasive in core transport networks. While current deployments in these networks consist mostly of 100 Gb/s channels, future ones will also include single carrier 200 Gb/s channels and super channels for 400 Gb/s and beyond, all of which in coherent formats. Meanwhile, metro networks also have started to evolve from(More)
