abstract:
- text: Dominating set based virtual backbones are used for rou-ting in wireless ad-hoc
networks. Such backbones receive and transmit messages from/to every node in the
network. Existing distributed algorithms only consider undirected graphs, which
model symmetric networks with uniform transmission ranges. We are particularly
interested in the well-established disk graphs, which model asymmetric networks
with non-uniform transmission ranges. The corresponding graph theoretic problem
seeks a strongly connected dominating-absorbent set of minimum cardinality in
a digraph. A subset of nodes in a digraph is a strongly connected dominating-absorbent
set if the subgraph induced by these nodes is strongly connected and each node
in the graph is either in the set or has both an in-neighbor and an out-neighbor
in it. We introduce the first distributed algorithm for this problem in disk graphs.
The algorithm gives an O(k^4) -approximation ratio and has a runtime bound of
O(Diam) where Diam is the diameter of the graph and k denotes the transmission
ratio r_{max}/r_{min} with r_{max} and r_{min} being the maximum and minimum transmission
range, respectively. Moreover, we apply our algorithm on the subgraph of disk
graphs consisting of only bidirectional edges. Our algorithm gives an O(ln k)
-approximation and a runtime bound of O(k^8 log^∗ n) , which, for bounded k ,
is an optimal approximation for the problem, following Lenzen and Wattenhofer’s
Ω(log^∗ n) runtime lower bound for distributed constant approximation in disk
graphs.
