Computing 2-Hop Neighborhoods in Ad Hoc Wireless Networks 185unit-disk graph. We need at least the distance in between any pair of adjacentnodes. Same arguments using rigid pieces apply when a node is able to computethe angle in between the segments to adjacent nodes. However, without any geographicalknowledge we do not know whether it is possible to compute 2-hopneighborhoods with O(n) messages each having O(log n) bits. This observationraises the interesting question whether there are any (meaningful) problemswhich have higher communication complexity on unit-disk graphs than on embedded(nodes aware of their geographical position) unit-disk graphs. Note thatit is NP-Hard to recognize unit-disk graphs [7].However, it follows from standard algebraic geometry results (page 542 of[17] or improved bounds in [4]) that the number of labeled unit-disk graphs of nnodes is between 2 c1n log n and 2 c2n log n , for constants c 1 and c 2 and therefore aprotocol with a total O(n log n) bits communication complexity is possible. AnO(n log n) bits communication complexity would follow from a solution to anopen problem in algebraic geometry [5]. It is worth mentioning that algebraicgeometry solutions seem to have huge running time and space complexity.Our model does not account for messages lost because of interference. Itwould be desirable to design synchronous distributed algorithms with low messagecomplexity and low time complexity in a model where messages are losteither due to signal interference or due to node overloading.AcknowledgmentsThe author thanks Peng-Jun Wan and Xiang-Yang Li, who inspired this paper bypresenting their results. The author thanks Sougata Basu, Adrian Dumitrescu,and Peter Sanders for insight in the issue of extending the results to case whengeographical knowledge is not available.References1. Khaled M.
