Over the past few years, mobile operators are faced with enormous challenges. Of such challenges, evolved user demands on personalized applications. Telecommunications industry as well as research community have paid enormous attention to Next Generation Networks (NGN) to address this challenge. NGN is perceived as a sophisticated platform where both application developers and mobile operators cooperate...
Mobile sensors networks are used in several domains to perform various tasks related to monitoring, recording, and affecting the conditions of an environment. Interacting with mobile sensor networks deployed in public networks requires an application capable of securely exchanging data in the network, generating mobile sensor network requests and processing mobile sensor network responses. Embedded...
We propose in this paper, to replace the two layer 3 Handover mechanisms defined for the situation of macro mobility with IP address change in IEEE 802.16e: ldquoClient-MIP and Proxy-MIPrdquo, by the new protocol created specially for the mobility without services interruptions: ldquoMSCTPrdquo, which has the peculiarity to support several IP sessions at the same time.The purpose of this proposal...
Mobile virtual private network (MVPN) has been developed to secure mobile user's communication between untrusted external networks and protected private internal network. The IETF's solution, however, leads to some problems: where should we put the external home agent (HA), how could we trust the external HA, and overhead of three tunnels. In this paper, we propose an alternative SIP-based MVPN. Because...
With the advent of future convergent systems consisting of an integration of different heterogeneous mobile and fixed technologies, the interconnection of mobile ad hoc networks (MANETs) to infrastructured IP networks (Integrated MANET) is becoming of paramount importance. Integrating MANET with infrastructured IP networks, such as the Internet, can improve communication in mobile ad hoc networks,...
