As mobile devices and wireless networks are becoming ubiquitous, the interest of users to deploy real-time applications, e.g., online gaming or Voice-over-IP in such environments is also increasing. Due to the difference between traditional and wireless networks, in particular in terms of available bandwidth and network structure, the concepts used for(More)
This paper introduces a series of new multipath routing protocols developed upon Associativity Based Routing (ABR) for wireless ad-hoc networks. ABR selects routes based on their stability and is an on-demand reactive routing protocol similar to Dynamic Source Routing (DSR) and Ad-Hoc On-Demand Distance Vector Routing (AODV). The multipath protocols(More)
This paper introduces the original concept of a cloud personal assistant, a cloud service that manages the access of mobile clients to cloud services. The cloud personal assistant works in the cloud on behalf of its owner: it discovers services, invokes them, stores the results and history, and delivers the results to the mobile user immediately or when the(More)

Mobile networks provide mobile users with access to computing services and resources anywhere, anytime. While each mobile device has limited resources and services, all of them, by networking, can create a powerful computing mobile platform. The role of the mobile middleware is to facilitate this platform. This paper discusses the main features of mobile(More)
Wireless ad hoc networks are created by mobile devices that contact each other while on the move. Within an ad hoc wireless network, a name service that allows nodes to discover services and resources is essential. This paper introduces a service-oriented attribute-based naming system for ad hoc wireless networks. An attribute-based name has the power of(More)
This paper presents a mobile agent information system designed as the basic tool for creating dynamic clusters. It is aimed at mobile and heterogeneous environments where needs for complex resources and services may arise from stationary or mobile devices of different computing capabilities. MAIS is part of a larger project that will offer users necessary(More)
One benefit of creating a mobile ad-hoc network (MANET) is that members with no direct access to the Internet can avail themselves of peers' connections to the Internet and use public cloud services. Guaranteed access to cloud services is important in the case of emergency or disaster recovery situations. As managing a MANET is a difficult task, this paper(More)
Self-organizing mobile ad hoc networks (MANET) allow devices to share their services and resources. MANET applications as diverse as multi-player games, disaster recovery, cooperative computing and mobile patient monitoring explain the high interest in these dynamic systems. However, the formation and management of MANET are challenging tasks due to(More)
This paper presents a novel system that allows mobile users to have access to healthcare services in the case of emergencies. The cloud hosts a directory service containing a list of pre-registered professionals, such as doctors and nurses. Once a registered user sends a help message to the first responder cloud service, a look-up operation is started to(More)
