Throughput enhancement to the Cognitive Radio networks under the precaution is better than the cure (PBC) approach

In this paper, we have proposed a Cognitive Radio system where primary users uses the precautionary measures against the possible interferences that may disturb their quality of service (QOS), these interferences may be originated from any other primary user itself, possibly due to the effect of the hidden terminal problem or may be received from […]

Cognitive Radio-Aware Transport Protocol for Mobile Ad Hoc Networks

With the proliferation of new wireless service, scarce wireless resources is expected to become a critical issue. For this reason, cognitive radio mobile ad hoc networks (CogMANET) are being developed as a promising solution to this problem. However, in CogMANET, channel switching is inherently necessary whenever a primary user with a license appears on the […]

PMU placement for HVDC connected network considering united and islanded conditions

PMUs play an essential rule in monitoring and control of power network. However, it is not possible to install PMUs at all buses of network, due to economical and technical constrains. Therefore, optimal PMU placement (OPP) is done to obtain full observability of network with minimum number of PMUs and maximum redundancy. On the other […]

Network economics in cognitive networks

Cellular networks are confronted with unprecedented pressure to accommodate the dramatically increasing demands of mobile Internet. This phenomenon is principally due to the restricted spectrum resource and low-efficiency spectrum management. Recently, cognitive radio technology has been corroborated to significantly improve spectrum utilization efficiency. In order to enhance the spectrum management efficiency in cellular networks, the […]

Nation-wide deployment of (long-reach) passive optical networks: Computing the location and number of active nodes.

For the European project DISCUS, we study the deployment of active nodes to connect all customers in different countries via (long-reach) passive optical networks. In particular, we investigate design parameters such as the resilience strategy, the maximum node size, and the maximum signal reach. We evaluate the resulting node distributions and survivable fiber route connections […]
