Fast flexible architectures for secure communications, ns-s simulation of wifimax networks.

Abstract

The 21^st Century is experiencing heavy dynamism in technology. There is rapid population growth across the world and therefore, a consequent need to bridge the gap on strain arising from various provisions. Such provisions include communication. Currently, there are notably high data needs across the population. This necessitates the need for fast, flexible, and secure communication procedures. Such procedures will help in realizing optimal communication and data acquisition practices amongst individuals. Worldwide interoperability for Microwave Access (WiMAX), commonly referred to as WifiMAX, is one of the key pathways to achieve the aforementioned communication procedures. WifiMAX is a wireless technology that focuses on the delivery of IP-centered services over a wide geographical coverage area. The core provision of this technology is in offering mobile broadband connectivity. The emergence of this technology was back in the year 2001. Since then, it has been evolving to fit the dynamism of the modern wireless communication world. The process of conceptualizing and laying out WifiMAX networks requires an elaborate procedure. To achieve a fast, flexible and secure network, there is a need for adequate planning. The NS-s (Network Simulators series), is a group of open-source software, which provides a platform for simulating the WifiMAX networks. The simulators include NS-1, NS-2, and NS-3. Of particular interest are the NS-2 and NS-3 simulators, which have proven to offer near-optimal solutions for model WifiMAX networks before their actual deployment.
