Challenges and Future Directions in Ad Hoc Networking-Review
Main Article Content
Abstract
Wireless networks have become increasingly popular in the past few decades, particularly within the 1990’s when they are being
adapted to enable mobility and wireless devices became popular. Ad hoc networks are a key factor in the evolution of wireless communications.
Self-organized ad hoc networks of PDAs or laptops are used in disaster relief, conference, and battlefield environments. An ad hoc network is a
(possibly mobile) collection of communications devices (nodes) that wish to communicate, but have no fixed infrastructure available, and have
no pre-determined organization of available links. This article is a survey on the current status and direction of research on ad hoc networking.
We categorize the on-going research and outline the major challenges which have to be solved before widespread deployment of the technology
is possible. The views presented by Perkins in [1] are used as a premise, which is then complemented with discussion and references to the latest
publications. Various approaches and protocols have been proposed to address ad hoc networking problems, and multiple standardization efforts
are under way within the Internet Engineering Task Force, as well as academic and industrial research projects.
