A mobile ad hoc network consists of only mobile nodes without the access points and the center server. In the mobile ad hoc network environment, a set of nodes in the network and the network topology are frequently changing due to the node appearance, the node disappearance, and the node movement so that it is not easy for users in the network to obtain the services provided in the network. Therefore,...
In mobile ad hoc networks, since nodes move around the network, the network topology and the number of neighboring nodes in each node frequently change. Although the number of neighboring nodes in each node and the distance between any two adjacent nodes always change, the transmission range of each node is not changed. Therefore, it is expected that many packet collisions among nodes occur and energy...
Recently, mobile terminals with wireless communication mechanism such as cell phones, PDAs or laptops are widely used and ad hoc networks have become popular. In mobile ad hoc networks, since nodes move around the network, the network topology and the number of neighboring nodes in each node frequently change. Although the number of neighboring nodes in each node and the distance between each node...
Recently sophisticated protocols for routing in ad hoc networks have been proposed, but there is still little work on service discovery in such volatile environments. In this paper a mobile agent-based scheme for service discovery in ad hoc networks is introduced. Mobile agents are traveling through the network, collecting the dynamically changing service information. The travel route and the number...
