We study deterministic gossiping in ad hoc radio networks with large node labels. The labels (identifiers)
of the nodes come from a domain of size N which may be much larger than the size n of the network (the number of nodes). Most
of the work on deterministic communication has been done for the model with small labels which assumes N = O(n). A notable
exception is Peleg's paper, where the problem of deterministic communication in ad hoc radio networks with large labels is
raised and a deterministic broadcasting algorithm is proposed, which runs in O(n
2log n) time for N polynomially large in n. The O(nlog
2n)-time deterministic broadcasting algorithm for networks with small labels given by Chrobak et al. implies deterministic
O(n log N log n)-time broadcasting and O(n
2log
2N log n)-time gossiping in networks with large labels. We propose two new deterministic gossiping algorithms for ad hoc radio
networks with large labels, which are the first such algorithms with subquadratic time for polynomially large N. More specifically,
we propose: a deterministic O(n
3/2log
2N log n)-time gossiping algorithm for directed networks; and a deterministic O(n log
2N log
2n)-time gossiping algorithm for undirected networks.
