Supporting range queries in a wireless environment with nonuniform broadcast

Tan, Kian-Lee; Yu, Jun X; Eng, Pin-Kwang


In a wireless computing environment, a server disseminates information by periodically broadcasting data on 'air', while clients 'catch' their desired data on the fly. To determine the data to be broadcast, the server constructs a broadcast program. While a nonuniform broadcast program has been demonstrated to be effective in reducing the average access times for single-record retrievals, existing nonuniform broadcast programs perform poorly for range queries. In this paper, we propose a new...[Show more]
