Session 5: Networks And Communications
نویسنده
چکیده
The need to support applications that are distributed on wide-local area networks or on multicomputer systems and that require large data transfer and low delay, drives the development of faster and more efficient ways of transporting and switching data. This work has led to the definition of new communication protocols and to the introduction in the telecommunication networks of fast packet-based data services, such as frame relay, switched multimegabit data services and asynchronous transfer mode (ATM) cell relay service.

IP session continuity in heterogeneous mobile networks using software defined networking
Smart environment requires uninterrupted connection when moving from one network to another. This is best accomplished at the network level (L3). Full interoperability and integration of heterogeneous networks is necessary for communication session continuity. Software Defined Networking (SDN) with virtual IP addresses solves the problem. Implementing a homogeneous SDN is expensive, given the e...
متن کاملA software architecture for GPRS session management
General packet radio service (GPRS) provides efficient access to the integrated services Internet from wireless networks. When the GPRS-attached mobile station attempts to send or receive data, a packet data protocol (PDP) context shall be established. The GPRS session management (SM) supports the PDP context handling, which consists of PDP context activation, deactivation, and modification pro...
متن کاملA DoS and fault-tolerant authentication protocol for group communications in ad hoc networks
In this paper, a novel authentication protocol is proposed, which satisfies both security and reliability requirements for group communications in ad hoc networks. The security features include identity anonymity and location intracability, periodic one-way session key and pseudonym identity refreshment with implicit authentication, dynamic joining and leaving an in-progress communication sessi...
متن کاملAn Enhanced Key Management Scheme Based on Key Infection in Wireless Sensor Networks
We propose an enhanced key management scheme based on Key Infection, which is lightweight scheme for tiny sensors. The basic scheme, Key Infection, is perfectly secure against node capture and eavesdropping if initial communications after node deployment is secure. If, however, an attacker can eavesdrop on the initial communications, they can take the session key. We use common neighbors for ea...
متن کاملA novel mechanism for anonymizing Global System for Mobile Communications calls using a resource-based Session Initiation Protocol community network
Considering the widespread adoption of smartphones in mobile communications and the well-established resource sharing use in the networking community, we present a novel mechanism to achieve anonymity in the Global System for Mobile Communications (GSM). We propose a Voice over Internet Protocol infrastructure using the Session Initiation Protocol (SIP) where a smartphone registers on a SIP reg...
