Abstract

In this paper we underline the importance of utilizing unequal powers in wireless ad hoc networks. Recent results from percolation theory indicate that a threshold exists after which a very large randomly positioned ad hoc network becomes disconnected almost surely for a given communication configuration. In this paper we prove that it is possible to extend the region of connectivity by allocating the transmit power of each node in an intelligent manner.
