【摘要】 针对DSR路由协议由于采用泛洪机制而导致的较高路由开销这一问题,提出了使用查询局部化技术的优化方案.即在原有的DSR协议的基础上引入查询局部化技术,将泛洪控制在一个局部的范围内,以防止整个网络内的泛洪,从而减小网络开销.仿真结果表明,使用查询局部化技术后,网络路由协议开销得到显著减小(约50%)并降低了平均端到端时延.更多还原

【Abstract】 To resolve the routing overhead problem of the DSR protocol resulted from flooding, this dissertation bring forward the optimization project using query localization technique, which can effectively limit the query to a small region. Simulations results show that the improved protocol reduce routing overhead notably, compared with DSR without using them.更多还原
