Abstract Power system faults can often result in excessively high currents. If sustained for a long time, such currents damage equipment. Thus, it is desirable to operate the relays minimum possible time. In this paper, busbar splitting approach used adaptive relay setting and co-ordination purposes integrity protection scheme (SIPS). Whenever fault occurs, splits bus convert loop into radial s...

abstract in recent decade, the research regarding wireless applications in e-health services has increased. simple communications, fast delivery of medical information, reducing treatment cost and reducing the medical workers error rate, are the main benefits of using wireless technologies in e-health applications. but on the other hand using wireless technologies causes the electromagnetic int...

In this paper, we consider the joint problem of relay selection and optimal power allocation for multi-relay amplify-and-forward (AF) cooperative communication system over frequency selective fading channels. An optimization model combined relay selection and power allocation under a total transmission power budget is formulated. Then, this combinatorial problem is solved in a distributed strat...

In cooperative relay networks with multiple users and multiple potential relays, which relay nodes are selected has great impact on the system performance. It is an optimization problem for selecting suitable relay nodes. The exhaustive search can solve this problem but the complexity will increase factorially with the network size, i.e., the number of users and the number of relays in the netw...

In this paper, we investigate the outage performance of multi-node relay network under equal power allocation (EPA) scheme. Due to the mobility of relay nodes, we proposed to design a method that considers random relay location based on random model. We conduct deep experiments which demonstrate that there exists optimal relay location to minimize the outage probability of multi-node relay netw...

—In this paper the outage-optimal relay deployment problem for amplify-and-forward (AF) multi-input multi-output (MIMO) two-way relaying network with antenna selection is studied. By utilizing an approximation of the outage probability, the outage-optimal relay location is shown feasible. On this basis a relay deployment scheme is developed by providing the near-optimal relay position in an ap...
