Autonomic Application-Level Message Delivery Using Virtual Magnetic Fields

Weighted Centrality by Potential for Replica Relocation in MANETs

“…This approach obviously aims at reducing the communication costs and delay [4]. In order to deal with changes in the environment, such as node speed and the availability of the node's resources, the concept of virtual magnetic fields [3] will be used, as mentioned in Section 1. Only the nodes that are direct neighbors of the node that has the replica (one hop) have an attraction force value (or "potential") computed from the current context information stored in each node.…”

“…The second portion of (1) IN(i) 1) as defined by (3). Notice that, the more frequently replica access requests are issued (or forwarded) by node i, and the more stable it its, the greater W(i) will be.…”

“…In this work is used of concept of Virtual Magnetic Fields (VMFs) [3]. This paradigm originally allows message forwarding through the construction of overlay networks representing attraction relations among nodes, so that messages are "attracted" towards the target nodes regardless of their location in the network [3].…”

The messages that arrive at a node are forwarded towards the node that exerts the greatest magnetic influence (or "attraction force") according to prearranged magnetic relations [4].…”

Applying Reputation to Virtual Magnetic Networks

“…This paper is organized as follows. Section II presents the Virtual Magnetic Fields distributed message routing paradigm [3] [4] and the EigenTrust reputation model [1]. After discussing the motivations for this work, Section III introduces the two proposed solutions for using reputation in virtual magnetic networks.…”
