Analysis of Mobile Ad-Hoc Networking Technology for Pervasive Computing | Original Article

ABSTRACT:

In the near future, a pervasive computing environment can be expected based on the recentprogresses and advances in computing and communication technologies. Next generation of mobile communications will include both prestigious infrastructure wireless networks and novel infrastructureless 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 pre-existing fixed network infrastructure. The special features of MANET bring this technology great opportunities together with severe challenges.This paper describes the fundamental problems of ad hoc networking by giving its related researchbackground including the concept, features, status, and applications of MANET. Some of the technicalchallenges MANET poses are also presented, based on which the paper points out some of the keyresearch 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 networklayer 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 networks. The introduction of pervasive computing in the last decade hasmade content adaptationan importantresearch  focus. Many content  adaptation approaches have been proposed  for pervasive computingenvironments. They are, however,fully or partially centralized whichmakes them unsuitable to a dynamic pervasive environment such as a Mobile Ad hoc NETwork (MANET). In this paper,we propose ConAMi, a Collaboration-Based Content Adaptation Middleware, for this type of environment.In this middleware, content adaptation is performed by the collaboration between co-located devices and is done bycomposing available services in the vicinity. The middleware implements a novel service composition algorithm which takes the dynamicity of services into consideration.
