The purpose of this paper is to solve a significant problem faced by waypoint-based robot navigation: the positions of the waypoints can be located in unreachable areas due to errors in selflocalization, the map, or in the waypoint data. Much research has focused on self-localization, but few studies have focused on estimating waypoints. The method presented in this paper estimates waypoints an...

Statistical Equivalent Models, or SEMs, have recently been proposed as a general approach to study computer simulators. By fitting a statistical model to the simulator’s output, SEMs provide an efficient way to quickly explore the simulator’s result. In this paper, we develop a SEM for random waypoint mobility, one of the most widely used mobility models employed by network simulators in the ev...

In pedestrian navigation, navigators are free to choose any passable way. Because of this characteristic, accurate route instructions are important when navigating from waypoint to waypoint. In this paper, a theoretical framework is described for dealing with position uncertainty in pedestrian guiding systems. Stages of closeness are defined based on the topological relation between the navigat...

ing the Route Representation and Finding Repetitions Next, we use the set of waypoints to create an abstracted and simplified route representation. We do this by iterating over the initial sequence of dots and, for each dot, recording the corresponding waypoint that the bot passes along the way. When a dot has no waypoint, we simply move on. Because each waypoint is uniquely identified, a seque...

In this paper, we are configuring an Adhoc mode scenario using QualNet as a Simulation tool to study impact of Random Waypoint mobility on QoS issues in MANET like Average end-to-end delay, jitter and throughput by varying number of nodes within a subnet. Different sets of reading were taken for six cases with varying number of nodes from 7 to 100 using CBR traffic type. We found that Random Wa...

In multi-hop wireless network simulation, mobility model is one of the crucial factors affecting the performance of networks. This paper aims to analyze the spatial distribution of Random Waypoint mobility models with the progress of time. Additionally, we study the network performance of a random-based mobility model. The results from the evaluation show the uniform node distribution of Random...

User mobility is of critical importance when designing mobile networks. In particular, ‘‘waypoint’’ mobility has been widely used as a simple way to describe how humans move. This paper introduces the first modeling framework to model waypoint-based mobility. The proposed framework is simple, yet general enough to model any waypoint-based mobility regimes. It employs first order ordinary differ...

Wide area research has been done in MANETs, with a major focus on the routing protocols in MANETs i.e AODV, DSR, OLSR and so many others. Much research has been done using different tools to study and analyze the performance of the routing protocols in MANET. Different results are shown by the different simulation environments depending on the number of mobile nodes, mobile node speed and varyi...
