This submission is being withdrawn due to serious errors in the achievability proofs. The reviewers of the journal I had submitted to had found errors back in 2006. I had forgotten about this paper until I saw the CFP for a JSAC issue on in-network computation. http://www.jsac.ucsd.edu/Calls/in-networkcomputationcfp.pdf.
翻译:由于可实现性证据存在严重错误,这一呈件被撤回。我提交的杂志的审评员在2006年发现错误,我忘记了这份文件,直到我看到菲律宾联邦统计局就网络内计算问题发表联合后勤咨询委员会的论文。 http://www.jsac.ucsd.edu/Calls/in-networkcomputationcfp.pdf。
