Virtual backbone has been proposed as the routing infrastructure to alleviate the broadcasting storm problem in ad hoc networks. Since the nodes in the virtual backbone need to carry other node's traffic, and node and link failure are inherent in wireless networks, it is desirable that the virtual backbone is fault tolerant. In this paper, we propose a new algorithm called Connecting Dominating Set...
In this paper, we investigate the transmission-power assignment problem for k-connected mobile ad hoc networks (MANETs), the problem of optimizing the lifetime of a MANET at a given degree k of connectivity by minimizing power consumption. Our proposed solution is fully distributed and uses a model-based transmission power adaptation strategy based on model-predictive control. Specifically, a stochastic...
Topology control is an important problem in wireless ad-hoc sensor networks. The aim of the topology control is to maintain desired properties of the network topology to improve the performance of networking algorithms (e.g. routing). In this paper, we present a distributed algorithm for assigning minimum possible power to all the nodes in the wireless sensor networks, such that the network is K-connected...
