Abstract
Evolutionary algorithms are metaheuristic algorithms that provide quasioptimal solutions in a reasonable time. They have been applied to many optimization problems in a high number of scientific areas. In this survey paper, we focus on the application of evolutionary algorithms to solve optimization problems related to a type of complex network like mobile multihop ad hoc networks. Since its origin, mobile multihop ad hoc network has evolved causing new types of multihop networks to appear such as vehicular ad hoc networks and delay tolerant networks, leading to the solution of new issues and optimization problems. In this survey, we review the main work presented for each type of mobile multihop ad hoc network and we also present some innovative ideas and open challenges to guide further research in this topic.
Highlights
Mobile wireless multihop ad hoc networks have attracted the attention of the scientific community for more than two decades [1,2,3,4]
Some studies have revealed that mobile multihop ad hoc networks are complex networks where many design parameters are intercorrelated [6, 7], which makes the use of analytical models to be optimized from a theoretical viewpoint very difficult
This survey paper has focused on a promising research field such as the application of evolutionary algorithms for optimization problems in multihop ad hoc networks
Summary
Mobile wireless multihop ad hoc networks have attracted the attention of the scientific community for more than two decades [1,2,3,4]. Even in the case that an analytical model is available, it may be very difficult to apply gradientbased optimization mechanisms that require to derivate the model in order to obtain the global maximum and minimum values This fact is encouraging the research community to explore new mechanisms to optimize the performance of mobile multihop ad hoc network, for instance, by using metaheuristic approaches like evolutionary algorithms. Another type of wireless multihop mobile network that has been deeply researched in recent years is represented by DTNs (delay tolerant networks) They are dynamically built when mobile devices collaborate to form communication paths while users are in close proximity. Information about ad views and clicks is encrypted and sent to the ad channel in an opportunistic way, via other mobile devices or static WiFi hotspots
