【摘要】 为满足移动自组网(MANETS)多级事务处理的安全性和并发性要求,将多版本两段锁协议运用到MANETS多级事务中。该协议有效地解决了由于竞争产生的错误的事务调度以及安全问题。模拟仿真结果表明,多版本两段锁协议在延迟截至时间率和重启动率方面比单一的多版本协议或者单一的两段锁协议都要低。更多还原

【Abstract】 In order to fulfill the MANET multi-level transaction security and concurrency,we have applied multi-version of two phase locking protocol in the multi-level transaction of MANET.The protocol effectively solves incorrect transaction scheduling and security issue,which are arised by competition.THE simulation emulation results show that multi-version two-phase locking protocol in delay time rate and restart rate are superior to single multi-version protocol or single two-phase locking protocol.更多还原
