Despite the fact that VANET brings huge benefits they present many challenges in terms of communication security. Traffic safety and management require real-time information and can influence life or death decisions. Without security, the system is wide open to a number of attacks, the spread of false warnings but also the suppression of real warnings leading to traffic accidents. The article presents the classification of different types of attacks in VANET. In addition, there are different types of adversaries and attackers. We focus on demonstrating network attacks in order to assess their impact on parameters affecting the quality and availability of services such as delay, throughput and data loss. Thanks to the implementation of the transport protocols UDP, TCP and the ICMP service protocol, we were able to monitor the impact of attacks on individual data transmissions depending on the growing probability of packet infiltration. The increasing probability of infiltration leads to a complete degradation of the quality and availability of services, which also reduces the reliability of the network. In general, the purpose of this article is to provide information about security and privacy in VANET and to point out to security risks that may lead to suppression of the availability of services and increase the complexity of the network.

To detect the number of agents needed to serve customers, it is necessary to consider the call centre as a mass service system. Then it is possible to asses the convenient number of agents according to the probability of the system receiving a request and the time in which the request is serviced by employing a Markov chain and the Erlang model. In an archetypal call centre, the incoming calls are added to a waiting queue and subsequently they are assisted by an agent. In case all agents are occupied, the customer has to wait in the queue until one of the agents becomes available. It is, therefore, important to compromise on the number of agents and the time the customers spend waiting in the queue. The result should be that there are enough agents in the call centre to serve the customers in the time required. This article focuses on solving this problem.

Providing IPTV in the IMS network is increasingly a problem solved today. All households are gradually passing through innovation and slowly every equipment becomes the so-called intelligent or smart and can be connected to a private or public network where it can be monitored, configured, diagnosed and then repaired.. This same upgrading takes place in television, and its current output is in the form of IPTV (Internet Protocol Television) provided in the IP Multimedia Subsystem Network, a new generation network that provides both audio and video data. IMS has originated in 1999 for the 3GPP standard in the 5th edition when switching from a 2G network to a 3G network. It has supported the older GSM and GPRS networks, but also a new UMTS network. In the sixth edition, it also has began to work on WLAN networks, more voice-oriented, or speech recognition services. This paper focuses on the provision of IPTV (Internet Protocol Television) in the IMS (IP Multimedia Subsystem) network. The aim of our paper is to design IPTV services in the IMS network, define the IMS architecture and the IMS network components such as HSS (Home Subscriber Server), various types of CSCF (Call State Control Function), describe the functionality and services provided by IMS and IPTV and, finally, compare the quality of the IPTV service provided by our network and by network of selected operator.
