This paper shows that, in an environment where we do not bound the number of faulty processes, the class P of Perfect failure detectors is the weakest (among realistic failure det...
We consider the following problem for wireless ad hoc networks: assume n nodes, each capable of communicating with nodes within a radius of r, are distributed in a ddimensional re...

We present the hybrid activation multiple access (HAMA) protocol for ad hoc networks. Unlike previous channel access scheduling protocols that activate either nodes or links only,...
This paper presents a new algorithm for dynamic routing of bandwidth guaranteed multicast tunnels with failure backup. The multicast routing problem arises in many contexts such a...
