The spatial temporal variations in the value of λ affects vehicular traffic flow. This study proposed a Congestion Control Model and perform simulation in MATLAB. In this model, vehicular density and number of vehicles were held constant while varying the value of λ from 1 to 10. The simulation result reveals the vehicle trajectories as the value of λ increases with time. The outcome of this study indicates that there is no need increasing the value of λ beyond 12, since further increases would only increase the number of vehicles leading to traffic jam. In principle, it is very important to use 1≤ λ ≤12 in designing traffic models in VANETs. The analytical result proved that the Congestion Control Model for the four-lane may be the most appropriate model to be adopted and use in designing VANETs networks.

The Shirt shape antenna is designed on FR-4 substrate and is fed through 50 ohm microstrip feed line. Two l-shape slots are introduced in antenna for size reduction and to provide multiband characteristics while DGS (defected ground structure) is used to achieve bandwidth enhancement. The simulated results show that the antenna operates in three different frequency bands having resonance frequencies at 4.4GHz, 6.2GHz and 8.5GHz. The antenna exhibits good return loss of -21.1dB @4.4Ghz, -15dB @6.2GHz and -30.5dB @8.5GHz. The proposed antenna has stable radiation patterns and gain values which are 5.3db at 4.4GHz, 5.03dB at 6.2GHz, 5.27 at 8.5GHz. The VSWR is also less than 2 and has good efficiency values at the operating bands 62%, 89% and 93% respectively. The Shirt shape antenna finds its applications in commercial WLAN, Wi-MAX and in Radar application.

As NFRs are quality attributes of the software system, so it must be dealt properly and with care in the early phases of software development otherwise it will lead the system to failure or dismissal of quality requirement at later phases. NFRs have a very unique ability to conflict and contradict among themselves. And the main reason behind this ability of NFRs is interdependency, which should be found and dealt properly in order to avoid requirement dismissal. Agile methodologies only focus on functional requirements but neglects non-functional requirements. In this work, we identified and highlighted all the possible dependencies between different NFRs in agile environment. In addition we also proposed a specific framework to cope up with the identified dependencies between NFRs.

RIP, Session, OSPF and BGP are the few commonly used dynamic routing protocols used in today’s networks. Routing refers to the phenomenon of selecting the best available path to forward packets to its destination. It is a core feature for any network because the performance of the networks heavily depends upon it. In this paper we will perform comparative analysis by using Distance Vector, Link State and Session routing protocol. We will study Packet drop rate (PDR), Bandwidth / Link Utilization, End to End Delay, throughput behavior of these protocols by using network simulator 2 (ns2) for route optimization & comparative analysis to find optimal routing protocol

These types of networks usually have to deal with intermittent disconnected path from source to the destination most of the time therefor suffers from numerous key challenges for successful custody transfer to be done between encounter nodes. There are numerous challenges faced due to such disconnectivity within the network but one of the key challenges is that which intermediate node will be selected as custody transfer and till how much time custodian node can carry messages as it will have storage constraints until a destination node is found. In this research study the same problem has been addressed via proposing a rule based expert system that will have better coordination among intermediate nodes for the transmission with less drop and better delivery ratio. Proposed technique has been tested and validated via ONE simulator and compared with MaxProp protocol.

SDN-based cellular networks provide high Quality of Services (QoS) to the end-user and NFV provides isolation. The sharing of resources is often provided by leveraging virtualization. SDN can generate new forwarding rules and policies for dynamic routing decision based on the traffic classification. However, virtualization in cellular networks is still in infancy and many issues and challenges remain unaddressed. The queue-length problem for providing QoS is cellular network requires attention. The queue management requires separate management protocols for fair allocation of resources. In this research paper, we propose a novel framework for resource allocation and bandwidth management in the 5G cellular network. We are using two level of virtualization, i.e., implementing dynamic resource optimization at network slice manager and executing optimized policies at the wireless virtual manager.
