摘要：The purpose of mobility models is to describe typical terminal movement so that the analysis for these purposes can be made. Thus, the movement pattern of users plays an important role in performance analysis of mobile and wireless networks, especially in thirdgeneration mobile communications. In this paper we propose algorithms for generating different mobility scenarios in ad hoc networks. Generating different mobility scenarios is one of the first tasks to be able to generate the three types of mobility patterns. We make two assumptions, first, the mobility pattern followed by the nodes in any particular scenario is homogenous, which means, the entire set of nodes follow any one particular type of mobility pattern. Second, the speed of the nodes remains constant through out the simulation. It is only the direction of the nodes which changes and hence resulting in various types of mobility patterns.
