As a member of INTRIG, presently I am involved in studying Slice Defined Cloud at UNICAMP sited under NECOS project
Understanding the network that gives programability on the network level and analyze its compatibility for larger data centres, have been my prime research Interests for the past few years.
My earlier publications fall into the following main areas: ZigBee network performance and workloads, cloud safety and firewall, load-sensitive routing, packet-scheduling architectures, mobility in SDN/SDWN architectures, and secuirty and Internet Protocols.Several of these papers are conference publications focusedon the Computing of Internet Service networks. I also have some blog articles online that describe the way I think about programable networks and Internet policies.
During the last couple of years of my research activities, I've had the pleasure to collaborate and be supervised by my respected faculties, groupmates and FIT researcher from abroad.
Working together on a focused project has given the chance to learn and evolve in the team working environment of healthy research fascilities. I've had no funding for most of my works, hence my groupmates, supervisors, advisors had shown me enough kindness being there to review my works when need
Here's a few of them I'm gratefully happy to work with in the past and present.
Software Defined Networking (SDN) is getting much attention for larger network implementation adding programmable feature in the network plane. Demand of wireless networking features is growing simultaneously. With increased network complexity and sizes, security has become an issue as vulnerabilities are still prominent for such complex network and needs to be monitored properly to provide early detection of security breaches and Denial of Service attack. Therefore, the communication protocols, an SDN architecture uses including OpenFlow, NETCONF, OpFlex and BGP etc. should be secure enough to manage such complex and large network. This paper analyzes mostly used protocols specifically for Software Defined Wireless Networking (SDWN): BGP, NETCONF, for underlying cloud or data center environment by applying Microsofts STRIDE security threat model. This work represents a comparative study among these most used protocols and holds appropriate network for their deployment.
Cloud computing is one of the highly flexible, confidential and easily accessible medium of platforms and provides powerful service for sharing information over the Internet. Cloud security has become an emerging issue as network manager eventually encounter its data protection, vulnerability during information exchange on the cloud system. We can protect our data from unwanted access on a hybrid cloud through controlling the respective firewall of the network. But, the firewall has already proved its weakness as it is unable to ensure multi-layered, secured accessibility of the cloud network. Efficient packet utilization sometimes causes high response time in accessing hybrid cloud. In this paper, a Cloud Model with Hybrid functionality and a secure Fuzzy Integrated Firewall for that Hybrid Cloud is proposed and thereby evaluated for the performance in traffic response. Experimental result illustrated that having a fuzzified firewall gives high point-to-point packet utilization decreasing the response time than a conventional firewall. Results from this research work will highly be implemented in transplanting artificial intelligence in future Internet of Things (IoT).
Ethernet network, standardized by IEEE 802.3, is vastly installed in Local Area Network (LAN) for cheaper cost and reliability. With the emergence of cost effective and enhanced user experience needs, the Quality of Service (QoS) of the underlying Ethernet network has become a major issue. A network must provide predictable, reliable and guaranteed services. The required QoS on the network is achieved through managing the end-to-end delay, throughput, jitter, transmission rate and many other network performance parameters. The paper investigates QoS parameters based on packet size to analyze the network performance. Segmentation in packet size larger than 1500 bytes, Maximum Transmission Unit (MTU) of Ethernet, is used to divide the large data into small packets. A simulation process under Riverbed modeler 17.5 initiates several scenarios of the Ethernet network to depict the QoS metrics in the Ethernet topology. For analyzing the result from the simulation process, varying sized packets are considered. Hence, the network performance results in distinct throughput, end-to-end delay, packet loss ratio, bit error rate etc. for varying packet sizes.
The Wireless Sensor Network (WSN) is spatially distributed autonomous sensor to sense special task. WSN like ZigBee network forms simple interconnecting, low power, and low processing capability wireless devices. The ZigBee devices facilitate numerous applications such as pervasive computing, security monitoring and control. ZigBee end devices collect sensing data and send them to ZigBee Coordinator. The Coordinator processes end device requests. The effect of a large number of random unsynchronized requests may degrade the overall network performance. An effective technique is particularly needed for synchronizing available node’s request processing to design a reliable ZigBee network. In this paper, region based priority mechanism is implemented to synchronize request with Tree Routing Method. Riverbed is used to simulate and analyze overall ZigBee network performance. The results show that the performance of the overall priority based ZigBee network model is better than without a priority based model. This research paves the way for further designing and modeling a large scale ZigBee network.
Today's mobile and wireless network are growing faster in size and complex to measure the services. Security is one of the most important aspects for such complex network and needs to be monitored properly to provide early detection of security breaches and Denial of Service attack. Tools that measure such detection of network threats and monitors network services requires internal security in their own mechanism. This paper analyzes two of such monitoring and measurement tools: sFlow and FlowVisor for underlying Software Defined Wireless Networking (SDWN) environment by applying STRIDE threat model. This analytical study represents that, sFlow requires an external secure deployment environment to ensure security in data flow and data store for SDWN. FlowVisor comes with secured access control in data store wherein isolated flow slice requires mechanism that improve its security.
ZigBee is a protocol for high-level communication under IEEE 802.15.4 standard. ZigBee network specification creates a personal area network for small, less-power consuming radio communication. The vast use in device to device communication of ZigBee turns its possibility in the use of the Internet of Things. A large amount of sensor nodes is interconnected through the Coordinator in ZigBee network. The end nodes send a huge amount of sensing data to the Coordinator via intermediary nodes like routers. These huge data creates overhead application traffic load in routers and Coordinator. A load balancing mechanism is necessary for a ZigBee network to contain multiple Personal Area Networks (PAN) and switch the threshold PAN loads with simplified network routing. This paper represents a novel ZigBee network model based on Stochastic and Widest Path process for proper traffic orientation, queuing and analyze load minimization issues. The two statistical models are put through in the ZigBee network using Riverbed to reduce and balance the overhead load. The result indicates that applying Stochastic process minimize the Medium Access Control (MAC) layer load as well as the overall ZigBee network load. This research will be helpful in large-scale integration of sensor nodes in a balanced ZigBee network for data load.
Wireless Sensor Network (WSN) is a group of the specialized wireless devices which forms a communication infrastructure at a diverse location. IEEE 802.15.4 standard for wireless devices like ZigBee has demonstrated its enormous application as WSN. ZigBee has got popularity for its both small range and wide range coverage. In wide range coverage, a large scale ZigBee network deployment is going ahead. Without proper network structure, a lot of sensor nodes needed for coverage. And also take down the network performance of the large-scale ZigBee network. This study, however, carries a new geometric structure to improve the formation of large scale ZigBee network and its performance. The network simulator Riverbed is used to design and implement a large ZigBee network in geometrical patterns. And also the network performance is analyzed by scrutinizing different network parameters. For real-time communication, free from network path is chosen according to the traffic inside the network. Finally, a deep analysis between two geometric structures - random and octagonal has presented with related parametric aspects. The analysis indicates the new octagonal structure shows significant performance in large scale ZigBee network deployment. This study will create a new opportunity to establish a reliable large-scale ZigBee network.
Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. ZigBee is the real time application for the WSN used for low-cost data and energy consumption characteristics. ZigBee is a robust network certain application of which has come out with a critically low designation for less data rate, long delivery delay and packet loss as well in order to lower the cost. However, ZigBee devices have many potential features to make a splendid wireless network. Hence, putting an improvement analogy inside the performance parameter is a way to overcome the limitations of ZigBee usage in certain scales. ZigBee follows a model for its node distribution, traffic routing and Quality of Service (QoS). The QoS indicates the efficiency and performance of any network. The increase in efficiency of QoS on the ZigBee network lies in the realization of maximizing throughput of the network. This paper is destined to represent the improved QoS in the ZigBee network applying Stochastic and Widest Path models. Riverbed Simulator v17.5 is used to investigate foremost QoS parameters in the ZigBee network. The optimized result of this study will be handy in the application field of the ZigBee network. And it also best fits for the deployment of the large-scale device to device communication.
