ABSTRACT: In the current scenario where we are using 3G and 4G technologies for communication purposes the Mobile Ad Hoc Networks (MANETs) are generating a lot of interests. The next generation of mobile communications will include both prominent infrastructure wireless networks (3G, 4G) and novel mobile ad hoc networks. It is a collection of portable wireless nodes that can dynamically form a network to exchange information without using any pre-existing fixed network infrastructure. This allows portable mobile devices to establish a communication path without having any central infrastructure. Since there is no centralized infrastructure in the MANET and the mobile devices are moving randomly, they may give rise to various kinds of problems, such as energy efficient and multicast congestion control. This paper describes the primary problems of ad hoc networking by giving its related research background. Some of the technical challenges it poses are also presented, based on which the paper points out some of the key research issues for ad hoc networking technology that are expected to promote the development and accelerate the commercial applications of the MANET technology. Special attention is paid on network layer routing strategy and key research issues include new X-cast routing algorithms, security & reliability schemes, QoS model, and mechanisms for interworking with outside IP networks.
