Typical sensor networks consist of users, sinks, and a number of sensor nodes. The traditional architecture usually assumes that there is a legacy network between users and sinks. However, practical users like firefighters and soldiers move around sensor fields and they might not have any direct communication through legacy networks. In other words, sensor networks are the only communication channel...
Mobility patterns of mobile ad hoc networks lead to update multicast routing information based on network multicasting. Thus, many control messages are likely to be generated, and bandwidth of wireless media and limited battery power of mobile nodes are inefficiently consumed. To improve the shortcomings, overlay multicast protocols on application layer has been proposed; however, some of them have...
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...
