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，Ouri 伊利诺伊大学芝加哥分校 CISE 实验计算机科学博士后：点对点广播网络中的数据复制 最近引起广泛关注的一个移动计算问题是数据广播。 问题是如何组织页面以广播方式从服务器向大量客户端传播信息。 一个密切相关的问题是如何在接收广播的移动单元中复制（或缓存）广播数据。 我们的研究涉及对等而不是客户端-服务器体系结构中的广播和复制问题的研究。 这些架构是由新兴的新型无线广播网络推动的，其中接收节点可能会断开、关闭或断电，并且消息可能会被损坏。 此外，由于通信成本的增加，通过确认和重传进行的可靠广播可能不合理。 博士后助理将探索点对点广播复制的基本原理：何时广播、广播什么以及衡量给定复制方法效率的成本函数。 将对各种广播复制算法进行分析和实验比较，助理将 1) 设计和分析各种广播复制算法，2) 设计和进行实验以比较这些算法。
