Nodes distribution and selection of accurate mobility Framework to systematically analyze its impact for improving performance of routing protocols for mobile ad hoc networks through Simulations

Abstract
Research on mobile ad hoc routing protocols performance based on simulation relies on choice of realistic mobility model. However, in the absence of realistic data movement, Synthetic models may be used for generating movement pattern. In order to capture the behavior of individuals moving in groups and between groups, there is a need for defining models for clearly representing group mobility based on the dimension of the relationships among the people carrying the mobile devices in mobile ad hoc networking scenarios. Sociability and attractivity between each group of hosts are the two main issues which may govern the pattern of movement of mobile hosts. Different mobility models have been proposed by researchers in the recent past for describing the movement pattern of mobile users, showing variation in their location, velocity and acceleration over time but most of them lack realistic behavior .As mobile ad hoc networks are not currently deployed on a very large scale and research in this area is mostly simulation based focusing on Mobility pattern constituting an important parameter in analyzing the performance of Mobile ad hoc routing protocols. Hence, it becomes necessary to study the behavior of mobility models and their impact on MANET routing protocols. In this paper we surveyed and examined different categories of mobility models proposed in the recent research literature and attempted to provide an overview of current research status of mobility modeling along with design principles for a perfect mobility model.
