“…To solve this problem, the authors use models and methods of teletraffic theory [10] or queuing theory [11], presented in the basic instructions on this topic. According to D. J. Kendall's classification denoted as M/M/v [1], the classical Erlang model [12,13] was used to calculate the number of operators in the early stages of the call center study. Also, some changes were made to the model to clarify the interaction between the customer and the help desk operator.…”

The paper considers the form of taking into account the specialization of information needs. An analysis of the work of modern call centers has been carried out. The authors noted the effectiveness of using IVR devices, operators, and consultants for differentiated customer service and the need to take feedback into account when forming the revenue stream of applications. The models make it possible to determine the leading indicators of the quality of service for applications arriving at the call center. Formal expressions for descriptions are derived from the input parameters' values and the model's stationary probability. The relationships between the characteristics of the call center that regulate the intensity of incoming and outgoing calls, call processing through 3CXPhone, corporate mail, and social networks were obtained using Global Statistic. The developed methodology for organizing information and reference systems makes it possible to consider modern trends in the development of call centers. The paper presents the results of research using the IP IVR system. The results of calculating service characteristics are given for two different types of calls with mixed order ω=(0.5; 0.7; 0.9). The presented results were obtained by using experimental data of the JSC Kazakhtelecom's call center. For the calculations, the authors used the formulas of the teletraffic theory for a mixed service system. It also assesses the extent of combined service model effects for the contact center's call quality. It is shown that the probability of lost calls depends on the incoming load. The obtained results show that the mixed order for incoming calls servicing affects the probability of service failure.

Real-Time Tracking and Authentication Protocol for Anonymous Operating Vehicles in Vehicle-Infrastructure Collaborative Systems

Vehicle-Infrastructure Cooperative Systems (VICS) are widely used in the safe driving and management of operating vehicles (OV). To preserve privacy and resist harmful attacks, digital certificates and signatures are used during vehicle communication. Nonetheless, the existing secure protocol cannot enable the road control center (RCC) to track the anonymous OV in real-time. To implement this additional functionality, this paper proposes a real-time tracking protocol for anonymous OV based on pseudonym certificates and Optimal Asymmetric Encryption padding (OAEP). In this protocol, pseudonym certificates ensure the security of the OV; the OV's real identity padding by OAEP is encrypted as a ciphertext, which is transmitted to RCC in communication, and RCC decrypts it to achieve real-time tracking. According to the security reduction proofs under the Elliptic Curve Discrete Logarithm Problem (ECDLP) given in the random oracle model (RO), the protocol can satisfy the security requirements. Additionally, the performance analysis based on MIRACL shows the protocol is slightly weaker than others, and we analyze the cost of real-time tracking for the reason. Finally, the RSU service rate of the protocol is analyzed according to the performance and velocity-density model, which proves the protocol is stable in this system.INDEX TERMS Vehicle-infrastructure cooperative systems, anonymous authentication, conditional privacy, elliptic curve, real-time tracking.

“…From Table 2, we have three performance metrics that are measured under various densities due to nonpredictive arrival rates. The definitions of all these metrics are taken from the queuing theory, as discussed in the reference in the context of telecommunication [39].…”

In recent years, an exponential increase has been witnessed in the population of the urban area worldwide, causing a significant increase in the use of transportation services. The traditional transportation system in metropolitan cities is overwhelmed, leading to many challenges. The Internet-of-Things- (IoT-) based technology has the potential to optimize transportation services in several ways. This paper highlights the challenges and consequences of an existing transportation system in Peshawar, Pakistan, in response to the rapid growth in population. Apart from the common issues, some areas in Peshawar are highly vulnerable to massive traffic jams. For this purpose, we have proposed an IoT-based framework for busy traffic junctions. The proposed framework considers the route selection problem as a game of two players, where Nash Equilibrium (NE) sets traffic for each route so that no individual can improve its performance by changing its strategy. NE calculates the traffic density from a roadside unit (RSU) collected data, which later detects and avoids traffic congestion by an alternate route selection. The framework in this paper provides a platform for the academia and transport department to convert the existing transportation system to IoT-based intelligent transportation in Peshawar, Pakistan.
