Abstract
Connectivity is the fundamental of the MANETs for end-to-end data transmissions.The robust network topology of MANETs is desired to meet the communication requirements
which has no hot spot nodes and can avoid network partition effectively.In this paper
the
k
-connectivity of MANETs is discussed
and an analytical expression of the probability of network
k
-connectivity is derived that enables the determination of the required critical transmitting range.The results of this paper are of practical value for the scenarios with high requirements on fault-tolerate of node failure in MANETs.
