EIA-0000516Wolfson, OuriUniversity of Illinois, ChicagoCISE Postdoctoral Associates in Experimental Computer Science: DataReplication in Peer to Peer Broadcast NetworksA mobile computing problem that has generated a significant amount ofinterest recently is data broadcasting. The problem is how to organize thepages in a broadcast from a server to a large client population in thedissemination of information. A strongly related problem is how toreplicate (or cache) the broadcast data in the mobile units that receivethe broadcast. Our research involves the study of the problems ofbroadcast and replication in a peer-to-peer rather than client-serverarchitectures. These architectures are motivated by new types of emergingwireless broadcast networks where receiving nodes may be disconnected,turned off or out of power, and messages may be corrupted. Further,reliable broadcasting by acknowledgment and retransmission may not bejustified due to increases in communication costs. The postdoctoralassociate will explore fundamental principles of peer-to-peer broadcastreplication: when to broadcast, what to broadcast, and the cost functionsto measure the efficiency of a given replication approach. Variousbroadcast replication algorithms will be compared analytically andexperimentally and the associate will 1) design and analyze variousbroadcast replication algorithms, and 2) design and conduct experiments tocompare these algorithms.

EIA-0000516Wolfson，伊利诺伊州的YouIniversity，实验计算机科学中的博士后协会：在PEER中dataReplication to Peer广播网络移动计算问题，最近产生了大量互动端，这是数据广播。 问题在于如何在信息中组织到从服务器到大客户群的广播中的页面。 一个密切相关的问题是，收到广播的移动设备中的广播数据是如何进行的。 我们的研究涉及在点对点而不是客户范围内的问题的研究和复制问题的研究。 这些体系结构是由新型的新型无广播网络激励的，在该网络中可能会断开接收节点，关闭或脱离电源，并且消息可能会损坏。 此外，由于沟通成本的增加，可靠的广播可能不会使人陷入困境。 博士后分析室将探讨点对点广播的基本原理：何时广播，广播什么以及成本函数仪衡量给定复制方法的效率。 将通过分析和经典地比较各种广播复制算法，并将对1）设计和分析各种播放复制算法，以及2）设计和执行实验这些算法。
