For positive integers k, d1, d2, a kL (d1, d2)-labeling of a graph G is a function f: V (G)→{0, 1,
2,…, k} such that| f (u)-f (v)|⩾ di whenever the distance between u and v is i in G, for i= 1, 2 …

Given any fixed non-negative integer values h and k, the L (h, k)-labelling problem consists
in an assignment of non-negative integers to the nodes of a graph such that adjacent nodes …

Multiple channels in Wireless Sensor Networks (WSNs) are often exploited to support
parallel transmission and to reduce interference. However, the extra overhead posed by the …
