We study the content delivery problem between a transmitter and two receivers through erasure links, when each receiver has access to some random side-information about files requested by other user. The is cached at via decentralized placement. distributed nature of receiving terminals may also make it harder for learn state links indices files. thus investigate capacity gain due various level...

Recent advances in mobile computing have enabled the deployment of broadcast based information systems such as, wireless internet, traffic information systems, etc. These systems are mainly pull-based and their performance very much depends on the broadcast schedule they use. In this paper we focus on on-demand broadcast system. We propose a new ondemand scheduling algorithm that takes scheduli...

The advances in computer and communication technologies made possible an ubiquitous computing environment were clients equipped with portable devices can send and receive data anytime and from anyplace. Due to the asymmetry in communication and the scarceness of wireless resources, data broadcast is widely employed as an effective means in delivering data to the mobile clients. For reasons like...

OF THE THESIS Wireless Broadcast Services by Nanyan Jiang Thesis Director: Professor Roy D. Yates In a mobile wireless communication network, broadcast signaling can be transmitted to multiple (two or more) receivers simultaneously. We define a coverage measure for broadcast transmission that counts both the data rate achievable by each user and the number of users receiving such data rate succ...

In two-way relay channels, bitwise XOR and symbol-level superposition coding are two popularnetwork-coding based relaying schemes. However, neither of them can approach the capacity boundwhen the channels in the broadcast phase are asymmetric. In this paper, we present a new physicallayer network coding (PLNC) scheme, called superimposed XOR. The new scheme advances the existing...
