Using mobile sinks to collect information in wireless sensor networks is an interesting area of research. As a result, a variety of mobility models were proposed by researchers over the years where each mobility model has its own properties that may affect the performance of the network in a way that differs from other models entitled with different properties. In this paper we provide a survey of mobility models that can be used in wireless sensor networks since it is important to provide a classification of the available models. Therefore, several mobility models were reviewed in the proposed work. These models were classified into two main categories namely homogenous and heterogeneous mobility. The goal of the work proposed in this paper is to provide researchers with a clear idea about the available mobility models and their properties. Additionally, we aim to provide researchers with guidelines to help them choose mobility models properly.
