We should avoid the pheromone accumulate infinitely before the pheromone trails get enhanced, so all pheromone trails are decreased by a factor. We define the transition probability from cluster head i to j for the kth ant as: ⎧ [τij (t)]α ·[ηij ]β ⎨ , j ∈ allowedk [τ (t)]α ·[ηik ]β k (1) pij (t) = k∈allowedk ik ⎩ otherwise 0, Where α is the pheromone heuristic factor, it reflect the residual pheromones importance of degree, β is the expectation heuristic factor, it reflect the expectation’s importance of degree.

Vi , vj ) is a unidirectional edge if (vi , vj ) ∈ E and (vj , vi ) ∈ E. If both (vi , vj ) ∈ E and (vj , vi ) ∈ E, that is to say d(vi , vj ) ≤ min{ri , rj }, then (vi , vj ) is a bidirectional edge. An undirected edge between u and v means both the unidirectional edge from u to v and the unidirectional edge from v to u belong to the edge set. Thus, in this paper, we also take the two-way link into consideration other than the directed links only. Before we describe the proposed algorithm formally, we introduce the definitions that will be used in the following parts.

Sun, H. Ma, and F. ): CWSN 2013, CCIS 418, pp. 41–50, 2014. c Springer-Verlag Berlin Heidelberg 2014 42 S. Wan et al. I ⊆ V is a independent set (IS) of G if no two nodes in I are adjacent. An independent set of G is a maximal independent set (MIS) if no more node can be added to form a larger independent set. Obviously, a MIS is a dominating set. A connected dominating set facilitates routing and adapts to the rapid changes of the network topology. Constructing a minimum connected dominating set in unit disk graph is a notable problem.
