摘要

A range assignment to the nodes in a wireless ad hoc network induces a topology in which there is an edge between two nodes if and only if both of them are within each other's transmission range. The critical transmission radius for $k$-connectivity is the smallest $r$ such that if all nodes have the transmission radius $r$, the induced topology is $k$ -connected. In this paper, we study the asymptotic critical transmission radius for $k$ -connectivity in a wireless ad hoc network whose nodes are uniformly and independently distributed in a unit-area square or disk. We provide a precise asymptotic distribution of the critical transmission radius for $k$ -connectivity. In addition, the critical neighbor number for $k$ -connectivity is the smallest integer $l$ such that if every node sets its transmission radius equal to the distance between itself and its $l$-th nearest neighbor, the induced (symmetric) t-n-nopology is $k$-connected. Applying the critical transmission radius for $k$-connectivity, we can obtain an asymptotic almost sure upper bound on the critical neighbor number for $k$-connectivity.
