To facilitate the mobile users on ships for communication effectively in the offshore areas at sea, this paper proposes an integrated wireless networking system that is composed of mobile ad hoc network, cellular mobile communication network, and satellite mobile network. The overall system architecture and relevant network elements of the proposed system are described. The proposed system can help...
The development in mobile devices and wireless technologies opens up unlimited choices of mobile services such as mobile commerce. These advances make access services available and convenient everywhere at any time. Since mobile users usually move, accessing services becomes unavailable especially in some locations that are not covered by their home networks. Therefore, it becomes necessary to roam...
In recent years, Caching technique (pull-based) in Mobile Ad hoc networks (MANETs) has become a promising technique in solving or mitigating the problems of performance, availability, scalability and resource paucity. MANETs consists of mobile nodes which communicate with each other through wireless medium without any fixed infrastructure. Mobile nodes may change rapidly and unpredictably over time...
The mobile agent is a computer program that can move between different hosts in heterogeneous networks. This paradigm is advantageous for distributed systems implementation, especially in mobile computing application characterized by low bandwidth, high latency and unreliable networks connections. Mobile agent is also attractive for distributed transactions applications. Although mobile agent has...
Nowadays, users of mobile phones generate too many files that have to be frequently downloaded to an external storage repository, restricting the user mobility. This paper presents a File Transfer Service (FTS) for mobile phones with scare storage resources. It is a support that can be used through a set of functions (API) that facilitates file transfer between mobile applications and external storage...
