The Node Distribution of the Random Waypoint Mobility Model for Wireless Ad Hoc Networks
This article considers a generalization of the random waypoint model in which the pause time of the mobile nodes is chosen arbitrarily in each waypoint and a fraction of nodes may remain static for the entire simulation time and derives an exact equation of the asymptotically stationary distribution for movement on a line segment and an accurate approximation for a square area.

On the minimum node degree and connectivity of a wireless multihop network
This paper derives an analytical expression that enables the determination of the required range r0 that creates, for a given node density ρ, an almost surely k--connected network and investigates two fundamental characteristics of a wireless multi -hop network: its minimum node degree and its k--connectivity.

Stochastic Properties of the Random Waypoint Mobility Model
The random waypoint model is a commonly used mobility model for simulations of wireless communication networks and some of its fundamental stochastic properties are investigated, including the transition length and time of a mobile node between two waypoints, the spatial distribution of nodes, and the direction angle at the beginning of a movement transition.

Self-organization in communication networks: principles and design paradigms
This article proposes four paradigms for developing a self-organized network function and shows how they are reflected in current protocols: design local interactions that achieve global properties, exploit implicit coordination, minimize the maintained state, and design protocols that adapt to changes.

Smooth is better than sharp: a random mobility model for simulation of wireless networks
This paper presents an enhanced random mobility model for simulation-based studies of wireless networks. Our approach makes the movement trace of individual mobile stations more realistic than commonExpand
Mobility modeling in wireless networks: categorization, smooth movement, and border effects
An enhanced random mobility model is presented, which makes the movement trace of mobile stations more realistic than common approaches for random mobility. Expand
On the Connectivity of Ad Hoc Networks
This paper presents a framework for the calculation of stochastic connectivity properties of wireless multihop networks, and compute a tight approximation for the critical (r0 ,n )pairs that are required to keep the network connected with a probability close to one. Expand
GSM phase 2+ general packet radio service GPRS: Architecture, protocols, and air interface
The general packet radio service (GPRS) is a new bearer service for GSM that greatly improves and simplifies wireless access to packet data networks, e.g., to the Internet. It applies a packet radioExpand
Connectivity of Wireless Multihop Networks in a Shadow Fading Environment
A tight lower bound for the minimum node density that is necessary to obtain an almost surely connected subnetwork on a bounded area of given size is given. Expand
The Spatial Node Distribution of the Random Waypoint Mobility Model
The spatial node distribution that results from using the random waypoint model is investigated, and an analytical expression of the expected node distribution in one dimension is derived and an approximation is given for the two–dimensional case. Expand
