Traditional medium access control (MAC) protocols utilize temporal mechanism to do contention resolution. This paper explores an alternative approach by adapting the space occupied by a transmission to resolve contention. Each successful transmission in a wireless network needs to occupy a certain part of space in which there are no other simultaneous transmissions. The size of the space occupied...
Recently power-aware routing algorithms for wireless ad hoc networks have drawn more and more attention. In this paper, we are focused on the routing algorithms aimed at maximizing networks lifetime. We provide a new maximum-lifetime routing algorithm DNLBR, whose routing procedure is directly based on the node lifetime, and we give a formal proof for its correctness. Moreover, by integrating power...
To provide reliable transmission in wireless ad hoc networks, two problems need to be solved. The first one is to find reliable routes for packets transmission. And the second one is to re-route packets as soon as possible when route failures occur. Aiming at solving these two problems, this paper proposes a reliable routing algorithm called QDSR by making two improvements to DSR. Integrating ETX...
