Survey on Multi-Objective Routing Optimization in Ad Hoc Networks

The chapter presents a survey on multi-objective routing issues to solve the problem of optimal path according to resources requirement or QoS preferences especially energy conservation. In the present work, we draw the set of uniformly and not uniformly improvable routing objective, highlight dependencies between them and what are the effects of that on establishing the objectives functions and how it can contribute to energy conservation and state of art of different multi-objective routing problem resolution techniques applied in ad hoc network context. Many methods developed with different answers to these questions are present in the literature; some of them are discussed here.
