Power distribution systems are conventionally designed as radial systems fed from a main source. However, when a distributed generation (DG) unit is connected to the system, the network is no longer radial. The presence of DG may affect existing protective relaying, especially overcurrent relays although DG has significant economic and environmental benefits. This paper proposed a novel protection...
We consider data-streaming from an access point to multiple receivers, which is modeled as packet erasure channel. A simple network coding is shown to achieve larger rate region than without network coding, using minimal control information. The performance is characterized exactly using state transition graph. The scheme is then mapped to an information theoretic formulation for broadcast channel...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
