Qos约束随机游走在移动自组网资源发现中的应用

针对目前移动自组网随机游走资源发现协议在请求转发过程中没有考虑Qos（Quality of Service）,使得选取的资源发现路径常常无法达到用户的要求,提出了将Qos约束条件应用到随机游走资源发现协议中,节点在随机转发请求分组时搜集邻居节点的剩余带宽、连接延迟和丢包率等信息,通过Qos计算公式计算出节点的Qos值,根据Qos值决定转发节点的选择或者丢弃,最终找到一条能够很好满足用户Qos需求的资源发现路径。

Qos constrained random walk in the application of the mobile ad-hoc network resource discovery

In view of the present mobile ad-hoc network random walk resource discovery protocol in the process of forward requests without considering the Qos,makes the selection of resource discovery path often can not meet the user＇s requirements,this article put forward the Qos constraints which is applied to the random walk resources found in the protocol,nodes at random forwarding request packet to neighbor nodes to collect the remaining bandwidth,connection information such as delay and packet loss rate,the formula for computing the Qos of compute nodes Qos values,according to the Qos value determines the selection of the forwarding nodes or discarded,eventually find a can satisfy user＇s Qos requirements of resource discovery path.
