MANET: THE ESSENTIAL TECHNOLOGY FOR PERVASIVE COMPUTING
Rupak Sharma, Manoj Kumar · 2012
A pervasive computing environment can be expected based on the recent progresses and advances in computing and communication technologies in near future. Next generation of mobile communications will include both prestigious infrastructure wireless networks and novel infrastructure less mobile ad hoc networks (MANETs). A MANET is a collection of wireless nodes that can dynamically form a network to exchange information without using any preexisting fixed network infrastructure. The special features of MANET bring these technology great opportunities together with severe challenges. This paper describes the fundamental problems of ad hoc networking by giving its related research background including the concept, features, status, and applications of MANET. Some of the technical challenges MANET 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 of MANET and key research issues include new X-cast routing algorithms, security & reliability schemes, QoS model, and mechanisms for interworking with outside IP
