In wireless broadcasting environments, mobile clients cannot receive data reliably over broadcast channels because a reliable transmission protocol is not applicable to the channels. If such broadcast errors are not properly handled by a concurrency control algorithm, it could lead to a fatal effect especially when clients are permitted to issue update transactions. However, the effects of broa...

Abstmcl-Recently, various schemes have arisen to broadcast continuous media data such as audio and video. Some of them have f w d on reduciug clients' waiting time under the continuin condition, ia, to play data completely without any intemptions These schemes us0aUy employ multiple channels to broadcast continnous media data. However, receivers of many existing broadcast systems such as those ...

Recently, Posner noted that on a wide-band Gaussian broadcast channel, ordinary time-shared coding performs almost as well as more sophisticated broadcast coding strategies. In this note, we shall give a quantitative version of Posner's result and argue that for certain realistic broadcast channels time sharing may suffice.

We study noisy broadcast networks with local cache memories at the receivers, where the transmitter can pre-store information even before learning the receivers’ requests. We mostly focus on packet-erasure broadcast networks with two disjoint sets of receivers: a set of weak receivers with all-equal erasure probabilities and equal cache sizes and a set of strong receivers with all-equal erasure...

This paper investigates the problem of communicating video over a broadcast channel. The broadcast channel is expressed in terms of the channel capacity that exists between the transmitter and each receiver in the broadcast area { Shannon's separation theorem does not apply for video communication over this class of channels. Digital (discrete time, discrete amplitude) and hybrid (discrete time...

of the Dissertation Encoding for Degraded Broadcast Channels and Resource Allocation for Content Distribution in Peer-to-Peer Networks by Bike Xie Doctor of Philosophy in Electrical Engineering University of California, Los Angeles, 2010 Professor Richard D. Wesel, Chair The broadcast communication network is a telecommunication network with exactly one source and multiple receivers. This disse...

A broadcast strategy for multiple access communication over slowly fading channels is introduced, in which the channel state information is known to only the receiver. In this strategy, the transmitters split their information streams into multiple independent information streams, each adapted to a specific actual channel realization. The major distinction between the proposed strategy and the ...

Absrfucr-Given two discrete memoryless channels @MC’s) with a common input, it is desired to transmit private messagea to receiver 1 at r&R, andcommon meswgea to both receivers at rate R,, while keeping receiver 2 as ignorant of tbe private messages as possible. Measurhg ignorance by equivocation, a single-letter characterization is given of the. achievable trfplea (RI&R,-,) where 4 is the equi...
