同时其发送路由的过程未对路径长给出明确的上界，易造成无限传输，无限等待

At the same time transmit its routing path length of the process does not give a clear upper bound, could easily lead to unlimited transfer, unlimited hunger waiting. Crowds [4] The user node configured as a cluster, each user node as a springboard to be transmitted, but each relay node on which are capable of acquiring communication content and can be traced back to the sender up. And when there is a failure node in the network, and efficiency will be greatly reduced degree of anonymity. Tarzan [5] during transmission, the path is a multiplex, this saves time on the surface of the route, once a path may be a problem, the entire network will be exposed.

At the same time, the process of sending routing does not give a clear upper bound to the path length, which can easily cause unlimited transmission, infinite hunger waiting. Crowds, which construct user nodes into a cluster, are transmitted each time using the user node as a springboard, but each relay node on it is able to obtain the communication content and trace it back to the sender. And when there are failed nodes in the network, their efficiency and anonymity are greatly reduced. During tarzan's transmission, the path is reused, which ostensibly saves routing time, but the entire network is exposed if there is a problem with the path.

At the same time, the process of sending route does not give a clear upper bound to the path length, which is easy to cause the hunger phenomenon of infinite transmission and infinite waiting. Crowds [4] constructs the user node into a cluster, each time uses the user node as a springboard for transmission, but each relay node on it can obtain the communication content and trace it to the sender. And when there are failure nodes in the network, its efficiency and anonymity will be greatly reduced. In the process of Tarzan [5] transmission, the path is reused, which saves the routing time on the surface, but once the path has problems, the whole network will be exposed.<br>
