QoS Routing for Mesh-Based Wireless LANs
White Paper Wireless LANs with their increased data rate become an attractive technology for connecting mobile users to the Internet. These networks extend the wireless LAN coverage by using each node in the network as a router, resulting in a multihop topology. [04 Aug 2008]
P-HCCA: A New Scheme for Real-Time Traffic With QoS in IEEE 802.11e Based Networks
White Paper Initial Hybrid Coordination Function (HCF) scheduling scheme does not adapt to Variable Bit Rate (VBR) traffic flows. Wireless Local Networks (WLANs) develops so fast that the ability of WLANs to support real-time multimedia communication with... [04 Aug 2008]
QoS Specific Medium Access Control for Wireless Sensor Networks With Fading
White Paper Referred to as QUality-of-service specific Information REtrieval (QUIRE), the proposed protocol optimizes the network performance under the metric of information rate per slot per Joule while ensuring a given QoS requirement. [04 Aug 2008]
Security in Wireless Sensor Networks
White Paper An even wider spectrum of future applications can be envisioned, such as real-time traffic monitoring, pollution tracking, home surveillance, fire and people sensors in buildings and other smart environments, wildfire tracking, water quality... [30 Jul 2008]
On QoS Management of H/2 Bearer Service for 3G Telecommunication Systems
White Paper 3G telecommunication systems encompass a high-speed access network, which can provide high bit-rate bearer services for roaming users, as well as intelligent allocation of backbone network resources for end-to-end QoS maintenance. [18 Jul 2008]
BT plans £1.5bn fat pipe upgrade
News But the company has said comms industry regulator Ofcom needs to look at changing the regulatory environment in order to ensure a "fair rate of return" for companies looking to roll out the technology. [15 Jul 2008]
Proportionally Fair Allocation of End-to-End Bandwidth in STDMA Wireless Networks
White Paper The design problem is posed as a utility maximization subject to link rate constraints that involve both power allocation and transmission scheduling over multiple time-slots. This paper considers the problem of designing distributed mechanisms for... [11 Jul 2008]
Highly-Resilient, Energy-Efficient Multipath Routing in Wireless Sensor Networks
White Paper Previously proposed sensor network data dissemination schemes require periodic low-rate flooding of data in order to allow recovery from failure. The paper considers constructing two kinds of multipaths to enable energy efficient recovery from... [11 Jul 2008]
Optimal Routing, Link Scheduling and Power Control in Multi-Hop Wireless Networks
White Paper First it address the problem of finding an optimal link scheduling and power control policy that minimizes the total average transmission power in the wireless multi-hop network, subject to given constraints regarding the minimum average data rate... [11 Jul 2008]
Arbutus: Network-Layer Load Balancing for Wireless Sensor Networks
White Paper The hot spot problem is a typical byproduct of the many-to-one traffic pattern that characterizes most wireless sensor networks: the nodes with the best channel to the sink are overloaded with traffic from the rest of the network and experience a... [10 Jul 2008]
A Genetic-Fuzzy Controller for Load Balancing in Wireless Cellular
White Paper In a cellular network, the call-arrival rate, the call duration, and the communication overhead between the base station and the mobile switch center are vague and uncertain. In this paper, a Genetic Algorithm-Fuzzy Logic Controller (GA-FLC) for... [10 Jul 2008]
Loop Detection in MPLS for Wireless Sensor Networks
White Paper Very few technologies illustrate the fast rate of technological innovations more than wireless sensor networks. Sensor networks offer a virtual path capability to carry differentiated services efficiently across the wireless backbone. [10 Jul 2008]
UK business lacking high fibre diet
News We are very clear that, if operators are going to make investments in new infrastructure, investment that is inherently more risky than developing the existing infrastructure, then they need to know that the regulatory framework will allow them to... [07 Jul 2008]
Ofcom: Mobile broadband driving interest in fibre
News The rapid take-up of mobile broadband could help spur the arrival of super-fast fibre broadband networks in the UK, says telecoms regulator Ofcom, which has set out plans for a pro-investment regulatory framework that will guarantee operators who... [04 Jul 2008]
Design of Spread Spectrum Multicode CDMA Transport Architecture for Multimedia Services
White Paper However, since the mobile radio channel has a fixed limited bandwidth, the traditional SS-CDMA system may not be sufficient to accommodate the Variable Bit Rate (VBR) multimedia services requested by multiple mobile users simultaneously. [03 Jul 2008]
