Many Mobile Agent Systems (MAS) have been developed, but with diverse proprietary Application Programming Interfaces (APIs). This propagation of incompatible APIs implies the complexity of communication and interaction inter-platforms. In a heterogeneous network, an agent may also need to cooperate with agents developed for different platforms. Furthermore, a group of cooperating agents and the...

Wireless communication infrastructure dependence is not always a suitable way to achieve mobile collaboration and communication processes for various scenarios. In those situations a MANET can take advantage of the independent signal range of every mobile device, in order to create communication channels between mobile users. This technical report presents an application level routing protocol ...

information technology has demolished time and distance. the new communication technologies have become dominant in contemporary world politics. the tools such as mobile phones, internet and satellite networks play supporting role in social changes with strengthening public space. we witness the effectiveness of new media in the recent unprecedented developments in arabic countries. the social ...

Mobile workers doing loosely coupled activities typically perform on demand collaboration in the physical workplace. Communication services available in such work scenarios are uncertain, therefore mobile collaborative applications supporting those activities must provide ad hoc communication mechanisms in order to use each cooperation opportunity. Typically, the complexity of implementing such...

With the increasing penetration of mobile phones, problematic use of mobile phone (PUMP) deserves attention. In this study, using a path model we examined the relationship between depression and PUMP, with motivations as mediators. Findings suggest that depressed people may rely on mobile phone to alleviate their negative feelings and spend more time on communication activities via mobile phone...

Mobile communication is experiencing significant growth: the domain has been completely reshaped since the launch of the Apple iPhone (June 2007) and the ensuing development of so-called “smart phones.” Furthermore, together with the expansion of new mobile artifacts, mobile application markets (such as Apple iTunes Store and Android Google Play market) have contributed to the diffusion of new ...

In this paper we present an architecture for a picocellular network and present a novel communication protocol for mobile users in such networks. The cell size in these networks is very small { typically of the order of a room in a building, resulting in an environment where the movement between cells is very rapid. This makes the problem of maintaining communication between a pair of mobile us...

For mobile roaming environment, the mobile uses visiting network’s services, the mobile station and the visiting network must authenticate each other. We propose a new authentication and anonymous channels protocol for roaming mobile communication. Our scheme can securely apply to GSM and CDPD wireless communication system, it’s not only supporting the mobile anonymity but also resolving the ch...

Recent communications environment significantly expand the mobile environment. Prepaid mobile services for 3G networks enables telecommunication to sign up new users by utilizing the latest in converged billing technologies. The worldwide mobile communication market is exploding, and 50 percent of subscribers are expected to use prepaid billing . Prepaid services are driving mobile communicatio...

The cell phone though the mobile communication system is proved to be an advantageous method of communication over wired communication, there is another problem that is the mobile phones get lost or get misplaced. The losses are increasing day by day and there has been very little effort that has been done to obtain the lost mobile phone. The main scope for this paper is “The proposal for the d...
