Abstract Mobility of connected wireless devices in ad hoc networks has been rising over these years leading to highly dynamic and unpredictable topology. Technology advancements have enabled these wireless devices to move in random directions with varying speeds. Routing of data packets from the source to the destination devices is a great challenge in these dynamic environments. Over these years researchers have proposed numerous routing protocols for efficient data delivery in these networks. Most of these protocols have been studied using simulations, in which mobility of devices are generated with different mobility models. Thus the accuracy of the performance analysis of routing protocols greatly depends on the respective mobility model used. The objective of this article is to analyze and compare the performance of the most popular random mobility models proposed for dynamic ad hoc networks using opportunistic routing.

INTRODUCTION Routing of data packets from the source to the destination devices in Mobile Ad Hoc Networks (MANETs) [1-2] has been a challenging task for researchers over these years. With the continuous rise in mobility of the connected devices, reliable routing of data packets has become very difficult [3-6]. The performances of routing protocols proposed for MANETs are evaluated using simulations in which mobility of
