Memcached通过在内存中开辟一块区域来维持一个大的hash表来加快页面访问速度，虽然和数据库是独立的，但是目前主要用来缓存数据库的数据。允许多个server通过网络形成一个大的hash，用户不必关心数据存放在哪，只调用相关接口就可。存放在内存的数据通过LRU算法进行淘汰出内存。同时可以通过删除和设置失效时间来淘汰存放在内存的数据-Memcached in memory by opening an area to maintain a large hash table to speed up

Zone Routing Protocol (ZRP) is a most promising and widely accepted and well proved hybrid routing protocol in Mobile Ad-hoc Networks (MANETs) for its performance when compared with table-driven and on-demand protocols. Our study is based on usin
