Towards a domain-specific aspect language for leasing in mobile ad hoc networks

Leasing provides a robust mechanism to manage reclamation of re- mote objects in mobile ad hoc networks. However, applying the leasing semantics on each remote object reference places a consid- erable burden on developers. Low-level leasing management de- tails can be abstracted away as much as possible by means of ded- icated language support. This paper focusses on the software en- gineering issues that arise using language support for leasing. We observe that the concerns dealing with leasing are inherently cross- cutting and argue in favour of a modularization of such concerns in an aspect. We propose a domain-specific aspect language (DSAL) for leasing which provides dedicated means to express the leasing concerns separately from the base functionality.
