Network Security: A Review Of Salient Security Aspects Of The Universal Mobile Telecommunication System (Umts), F. Imran, M. Hussain
Network Security: A Review Of Salient Security Aspects Of The Universal Mobile Telecommunication System (Umts), F. Imran, M. Hussain
International Conference on Information and Communication Technologies
Wireless communication is known as key to global development. Wireless and mobile communication is gaining more importance in our life. Protecting information is one the aspects which we need to focus on the wireless networks. Universal mobile telecommunication system (UMTS) is evolution of the third generation mobile communication system. It was built on the success of global system for mobile communication (GSM). Universal mobile telecommunication system's security is also built on global system for mobile communication (GSM). The paper reviews the literature of the security aspects of the Universal mobile telecommunication system. A critical evaluation of the proposed solutions is …

International Conference on Information and Communication Technologies
On Demand Transmission Power Control (ODTPC) is a well known transmission power control strategy that is used to reduce high power consumption in wireless sensor networks (WSNs). In this paper, we propose an extension to ODTPC and thus, a modified version of ODTPC is proposed named MODTPC. Simulation results show that performance of MODTPC is better than ODTPC in terms of efficiency and energy saving.

International Conference on Information and Communication Technologies
Voice over IP “VoIP” is a form of voice speech that uses data networks, for transmission of voice traffic over IP-based networks to transmit voice signals. The signal is correctly encoded at one end of the communication channel, sent as packets through the data network, then decoded at the receiving end and transformed back into a voice signal. It has a potential and offering a choice to the traditional telephony systems due to its high resource utilization and cost efficiency. Meanwhile, Wireless Local Area Networks (WLANs) have become an ever present networking technology that has been deployed around the world. …

Networks - I: Interference Mitigation In 4g System Using Smart Antenna, Asad Ali Siddiqui, Muhammad Mazhar Manzoor, Aamir Ijaz, Adnan Umar Khan, Imran Ahmed Awan, Sangita Lal Chand
International Conference on Information and Communication Technologies
Emerging trends of mobile communication and ever growing demand of mobile users with high speed data requirements and migrating towards 4G, Co-Channel interference and multipath in urban/dense urban environment will limit the capacity of the network. Smart antenna is now recognized by its higher user capacity in 4G wireless networks by efficiently reducing multipath and co-channel interference. Smart Antenna use adaptive beam forming algorithms in a dynamic environment continuously adjusting the weight of antenna arrays for creating a beam to track desired users automatically, and minimize interference from other users by placing nulls in their directions. This research work provides …
Artificial Intelligence – I: A Preliminary Framework For Human-Agent Communication In Electronic Negotiations, Moez Ur Rehman, Nosheen Riaz
Artificial Intelligence – I: A Preliminary Framework For Human-Agent Communication In Electronic Negotiations, Moez Ur Rehman, Nosheen Riaz
International Conference on Information and Communication Technologies
Electronic negotiations are business negotiations conducted via electronic means using information and communications technologies (ICT). Two dominant types of electronic negotiation systems are automated negotiation systems for software agents and negotiation support systems (NSSs) for humans. However, the integration of two types for human-agent negotiations is an important task. In this paper, an extended communication model for human-agent business negotiations is presented. For this purpose, the underlying communication models of automated negotiations and NSSs are analyzed. The extended communication model is based on a common negotiation ontology which captures the negotiation agenda and paves the way for such hybrid communication, …
