Tree topology information gathering protocols has been proposed in order that sinks can efficiently collect continuous data. In other words, sensor network initially constructs connection structure from sources to sinks. After that, continuous data are delivered to sinks through the connection structure. These protocols, although, could not be applied to the model of mobile sinks because the connection...
Wireless sensor networks traditionally consists of sensors perceiving data and sinks gathering the data. In addition, users received required information from the sinks via infrastructure networks. The users, however, should receive the information from the sinks through multi hop communications of disseminated sensor nodes if such users move into the sensor networks without infrastructure networks...
