A bend in a single-conductor line is primary cause of radiation associated with the antenna mode; conversely, fed back, resulting attenuation and distortion current waveform. Despite being fundamental phenomenon, its dynamics have not been sufficiently characterized. Therefore, this study presents transmission-line model for bent wire structures comprising multiple straight elements by using lo...

Standard compliant enhancements of the emerging H.264/AVC coding algorithm for transmission over lossy IP-based networks are described with the error resilience features being presented in greater detail. Standard compliant encoder and decoder enhancements as well as the exploitation of transport layer mechanisms to improve the quality in packet lossy environments are presented. Different schem...

There is a great resolution calling for smart grids in recent years. Introduction of new technologies, that make the network flexible and controllable, is a main part of smart grid concept and a key factor to its success. Transmission network as a part of system network has drawn less attention. Transmission switching as a transmission service can release us from load shedding and remove the co...

In this paper we analyze the performance of a TCP-like flow control mechanism in a lossy environment. The transmission rate in the control scheme that we consider has a linear growth rate; whenever a loss occurs, the transmission rate is halved. This approximates the performance of several versions of TCP that divide their congestion window by two when a loss is detected. We propose a mathemati...

Simple sets of equations have been derived to describe the absorption of microwave power in three-region, lossy transmission lines in terms of S-parameter reflection and transmission amplitudes. Each region was assumed to be homogeneous with discontinuities at the region boundaries. Different sets of equations were derived to describe different assumptions about the amplitudes of the reflection...

In Wireless Sensor Networks (WSNs), transmission errors occur frequently due to node failure, battery discharge, contention or interference by objects. Although Directed Diffusion has been considered as a prominent data-centric routing algorithm, it has some weaknesses due to unexpected network errors. In order to address these problems, we proposed a radio-aware routing algorithm to improve th...
