In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...

nowadays, with technology progress and the emergence of new business models, increased levels of competition and changing demands and expectations of customers, using multi channels of distribution is growing rapidly. the coordination and integration of these channels with high efficiency and the elimination of these challenges requires more discussion. the purpose of this study is to investiga...

a communication net is usually represented by a linear graph g whose branches represent channels for information flow and whose vertices represent sources, sinks and switching centers. the purpose of this paper is to show that for modeling digital communication nets, conventional use of the concepts of capacity and terminal capacity is inadequate . we will present an alternative to max-flow min...

A research can also reveal the cooperative effectiveness of agencies such as evaluation will lead to discover the weakness and strengths for further improvement of this program. The present study was designed in 2009 especially to see the effectiveness of the working of agricultural extension staff as perceived by farmers in district Okara-Pakistan. The data were collected with the help of a sp...

This paper aims at bridging the gap between the assumption of reliable channels by fault-tolerant distributed algorithms and the weak reliability of feasible communication channels. We deene a new kind of communication channels which we call Stubborn channels. Stubborn channels are easily implementable over a connectionless network layer and, although weak, the reliability guarantees ooered by ...
