One of the most significant challenges introduced by mobile networks is coping with the unpredictable motion and the unreliable behavior of mobile nodes. In this paper, we define the Virtual Mobile Node Abstraction, which consists of robust virtual nodes that are both predictable and reliable. We present the Mobile Point Emulator, a new algorithm that implements the Virtual Mobile Node Abstraction...
This paper presents the first algorithm for implementing selfstabilizing group communication services in an asynchronous system. Our algorithm converges rapidly to a legal behavior and is communication adaptive. Namely, the communication volume is high when the system recovers from the occurrence of faults and is low once a legal state is reached. The communication adaptability is achieved by a new...
Self-stabilizing group membership service, multicast service, and resource allocation service in directed network are presented. The first group communication algorithm is based on a token circulation over a virtual ring. The second algorithm is based on construction of distributed spanning trees. In addition, a technique that emulates, in a self-stabilizing fashion, any undirected communication network...
The paper presents a technique for achieving stabilization in distributed systems. This technique, called agent-stabilization, uses an external tool, the agent, that can be considered as a special message created by a lower layer. Basically, an agent performs a traversal of the network and if necessary, modifies the local states of the nodes, yielding stabilization.
