Mobile ad hoc networks are the ones which allow mobile nodes to spontaneously form a network and share their services. The dynamic environment of MANETs (Mobile Ad hoc NETworks) demands service selection should not only base on functional properties but also be driven by non-functional requirements. In this paper, the authors present a modelling method of non-functional properties. The degree of impact of the property on QoS (Quality of Service) may vary. So, they allow the application designer to define weight for each property. The evaluation function for the properties cannot be uniform as the type of the property may be Boolean, string or numeric depending upon the nature of the property.
