Powerline carrier (PLC) communications have been heralded by the FCC as the ‘‘3rd wire’’ to every home, and have matured to the point of field trials and limited deployment. This paper examines the technology from a techno-economic perspective, factoring in regulatory issues and network design (focusing on the United States). Results indicate that PLC does not appear to represent a major disrup...

This paper presents two automatic cellular network design algorithms which determine the favourable positions of transmitters with respect to co-channel interference (CCI). The proposed methods are capable of maximizing the average CCI ratio in the planning region while optimizing the covered teletra c demand. Additionally, we investigate how the proposed algorithms can be extended for locating...

The uplink coverage and capacity of CDMA cellular systems are intracell and intercell interference limited. In this work, we propose a practical multihop based cellular network design to enhance the uplink performance. The proposed design is based on dividing each cell into two regions where users belonging to an inner region communicate with the base station (BS) using one hop and users belong...

This paper presents an automatic cellular network design algorithm which determines the location of transmitters with respect to co-channel interference (CCI). The proposed method is capable of maximizing the average CCI ratio in the planning region while optimizing the covered teletra c demand. Additionally, we investigate how the proposed algorithm can be extended for locating microand macro-...

Community networks are digital infrastructures designed to strengthen bonds and build social capital between members of a community, facilitating accomplishment of goals. As we consider how community network implementations can be improved, we recognize the potential that social translucence and activity notification introduces to other forms of CSCW. We investigate how the underlying notion of...

The performance of a multi-hop Ultrawideband (UWB) sensor network based on Aloha multiple access technique is evaluated in terms of the average link outage probability and the overall network throughput for different coverage radius of the UWB sensor device. The architecture of the considered sensor network is based on the creation of multi-hop routes using intermediate nodes for each source-de...

for any agency dealing with the design of the water distribution network, an economic design will be an objective. in this research, central force optimization (cfo) and differential evolution (de) algorithm were used to optimize ismail abad water distribution network. optimization of the network has been evaluated by developing an optimization model based on cfo and de algorithm in matlab and ...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
