The high-level contribution of this paper is the design and development of a unicast stable path routing protocol (referred to as SILET) that determines long-living routes based on the Inverse of the Link Expiration Times (LET) for Mobile Ad hoc NETworks (MANETs). From a graph theoretical perspective, the authors model SILET as a minimization problem to discover stable routes with the lowest value for the sum of the link weights; the weight of a link defined as 1 plus the inverse of the LETs. The inclusion of '1' in the link weights helps to reduce the number of constituent links of the paths (i.e. the hop count).
