Networks without fixed infrastructure are generally termed as ad hoc networks. Ad hoc networks find application in various areas including military, forestry where centralized base station is not feasible. Selecting an effective routing protocol is a major challenge in ad hoc networks. Reactive or on-demand routing protocols are more suitable as it reduces control overhead as well as reduction in control packet flooding. Here the authors presented a survey on various on-demand or reactive routing protocols used in ad hoc networks.
