Gossiping with bounded size messages in ad hoc radio networks (Extended abstract)
(2002) 29th International Colloquium, ICALP 2002 In Automata, Languages and Programming / Lecture Notes in Computer Science 2380. p.377389 Abstract
 We study deterministic algorithms for the gossiping problem in ad hoc radio networks under the assumption that each combined message contains at most b(n) single messages or bits of auxiliary information, where b is an integer function and n is the number of nodes in the network. We term such a restricted gossiping problem b(n) gossiping. We show that rootngossiping in an ad hoc radio network on n nodes can be done deterministically in time (O) over tilde (n(3/2)) which asymptotically matches the best known upper bound on the time complexity of unrestricted deterministic gossiping(dagger). Our upper bound on rootngossiping is tight up to a polylogarithmic factor and it implies similarly tight upper bounds on b(n)gossiping where... (More)
 We study deterministic algorithms for the gossiping problem in ad hoc radio networks under the assumption that each combined message contains at most b(n) single messages or bits of auxiliary information, where b is an integer function and n is the number of nodes in the network. We term such a restricted gossiping problem b(n) gossiping. We show that rootngossiping in an ad hoc radio network on n nodes can be done deterministically in time (O) over tilde (n(3/2)) which asymptotically matches the best known upper bound on the time complexity of unrestricted deterministic gossiping(dagger). Our upper bound on rootngossiping is tight up to a polylogarithmic factor and it implies similarly tight upper bounds on b(n)gossiping where function b is computable and 1 less than or equal to b(n) : rootn holds. For symmetric ad hoc radio networks, we show that even 1gossiping can be done deterministically in time (O) over tilde (n(3/2)). We also demonstrate that O(n(t))gossiping in a symmetric ad hoc radio network on n nodes can be done in time O(n(2t)). Note that the latter upper bound is o(n(3/2)) when the size of a combined message is w(n(1/2)). Furthermore, by adopting known results on repeated randomized broadcasting in symmetric ad hoc radio networks, we derive a randomized protocol for 1gossiping in these networks running in time (O) over tilde (n) on the average. Finally, we observe that when a collision detection mechanism is available, even deterministic 1gossiping in symmetric ad hoc radio networks can be performed in time (O) over tilde (n). (Less)
