A wireless ad hoc network [1] (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes.
Mobility models are used for simulation purposes when new network protocols are evaluated. The random waypoint model was first proposed by Johnson and Maltz. [2] It is one of the most popular mobility models [3] to evaluate mobile ad hoc network (MANET) routing protocols, because of its simplicity and wide availability.
Mobility models characterize the movements of mobile users with respect to their location, velocity and direction over a period of time. These models play a vital role in the design of Mobile Ad Hoc Networks(MANET) .
As part of the congestion-pricing scheme, ride-hailing services like Uber and Lyft were slapped with an additional $1.50 surcharge for trips within the congestion zone, but the state allowed those ...
An alternative, called "perfect simulation", is to sample the initial simulation state from the stationary regime. There exists algorithms for perfect simulation of the general restricted random waypoint. They are described in Perfect simulation and stationarity of a class of mobility models (2005) [2] and a Python implementation is available ...
The Manhattan mobility model is a guide which leads the driver of a vehicle on the correct path. It is an urban type of mobility model for vehicular ad-hoc networks (VANET). The Manhattan mobility model uses a "grid road topology. It works optimally where streets are in an organized manner.
Stimulant medications and certain therapies are more effective in treating ADHD symptoms than placebos, a new study on more than 14,000 adults has found.
Australian homicide detectives are investigating the suspected "targeted double murder" of a Sydney couple. On Tuesday, Dec. 17., New South Wales (NSW) police confirmed a second body had been ...
