Mobility Control for Complete Coverage in Wireless Sensor Networks
In this paper, we propose a new control method to cover the ā€œholesā€ in wireless sensor networks. Many applications often face the problem of holes when some sensor nodes are d...

Bounded Degree Closest k-Tree Power Is NP-Complete
Abstract. An undirected graph G = (V, E) is the k-power of an undirected tree T = (V, E ) if (u, v) ∈ E iff u and v are connected by a path of length at most k in T. The tree T ...
