PEER-TO-PEER AD HOC NETWORK: AN OVERVIEW?

Past few years, we have seen a rapid expansion in the field of mobile computing due to the proliferation of inexpensive, widely available wireless devices. Fourth-generation wireless networks may require an integration of mobile ad hoc networks (MANET) into external network to improve the flexibility of the communication and travelling. This occurrence is well-suited for commercial and other things. However, current devices, applications and protocols are solely focused on cellular or wireless local area networks (WLANs), not taking into account the great potential offered by mobile ad hoc networking. Application scenarios are not limited to emergency and rescue operations, conference or dormitory settings, automobile networks, personal networking, etc. This paper describes the concept of ad hoc networking by giving its background and also point out some of the applications that can be envisioned for ad hoc networking. Paper contains information on MANET for wireless ad hoc networking.
