Large-scale wireless multi-hop networks are fast becoming the most preferred way for communication in outdoor environment. Each user in a wireless multi-hop network could initiate a communication in a multi-hop fashion without of the aid of any network infrastructure. Thus, the maintenance cost for communication networks can be significantly reduced. However, relays of a wireless multi-hop network may be also users, which are highly unreliable due to the unexpected user behavior and the time-varying wireless channel. Thus, it is highly possible that a connection may get lost during data transmission, in which case the data has to wait at some node and resume its transmission after the reestablishment of the network connection.
