—We consider a point-to-multipoint cognitive radio network that shares a set of channels with a primary network. Within the cognitive radio network, a base station controls and s...

-We derive bounds for the performance of dynamic channel assignment (DCA) schemeswhich strengthenthe existing Erlang bound. The construction of the bounds is based on a reward para...
Abstract— We study the problem of establishing secure communication channels in resource-constrained wireless networks using key predistribution. Pairwise communication channels ...
The issue of transport capacity of a randomly deployed wireless network under random (c, f ) channel assignment was considered by us in [1]. We showed in [1] that when the number ...
In this paper, we propose a TDMA slot assignment protocol to improve the channel utilization, which controls the excessive increase of unassigned slots by changing the frame lengt...
