Research Topic: Analysis of Temporally Evolving Social Network Patterns

 

Research Abstract: In this work, we propose to investigate different techniques for identifying temporal patterns and events in social networks that evolve over time. We present a framework for detecting the evolution of dynamic social communities, along with tracking the events and transitions related to communities. These events can be considered as building blocks for pattern detection in networks with evolving communities. These detected events and transitions could then be used for predicting the future patterns of these social networks.

Research Topic: Opinion Mining Challenges of Social Media Content & Sentiment Polarity Detection.

 

Research Abstract: Experiences and viewpoint expressed by others have always been important part of decision making process. In current era very large pool of public opinion is available on social media about certain event. These web contents are unstructured data set and a rich source for not only commercial exploitation but also for psychological & sociopolitical research. Our proposed research aims to find an efficient method to extract important features/ aspect about a particular event from social media message and then do the features based sentiment analysis about the same. The proposed method can be adapted to work for text from other online media as well.

Research Topic:  Securing the Internet of Things Environment against RPL (Routing Protocol for Low power and Lossy Network) Attacks

Research Abstract: Internet of Things (IoT) is network of uniquely identified devices that have the ability to talk to each other without requiring human intervention. IoT devices are constrained which makes it difficult to implement complex security solutions on them. The communication is wireless, which also makes it susceptible to attacks. Also, the devices are mostly placed in locations which cannot be frequently accessed. These characteristics of IoT make it vulnerable to breaches in privacy and security. An effective way to prevent attacks is to have secured bootstrapping. Secure bootstrapping in IoT involves design of light weight cryptographic algorithms. RPL is the Routing protocol used in LLNs in IoT, which is vulnerable to several security attacks. Hence, it is important for an IoT network to have a holistic system to address the RPL attacks. The research topic aims to develop such a system, which can identify the RPL attacks, take action to counter it and also design secure bootstrapping algorithms for authentication of new nodes joining the IoT network.

Research Topic:   Estimators for Efficient Buffer Management in Mobile Opportunistic Networks.

 

Abstract of the Research:

Most of the congestion control mechanisms that have been proposed, have a common goal of increasing the message delivery ratio and decreasing the message delivery delay. To achieve this goal, several congestion mechanisms employ dropping the message or try to transfer the message to other nodes. Existing research shows that the several congestion control mechanisms are dependent on the underlying routing protocol. As a result, the congestion control mechanisms are not interoperable with variety of routing protocols. Many existing congestion control mechanisms relies completely on the network information to make the congestion control decisions. Several congestion control algorithms depend on the simulation platforms to evaluate protocols and algorithms, which is a necessary step, but cannot replace the real world experiments. In our work, we aim to use controlled message replication policies to increase the congestion control strategy range to various routing protocols. We also intend to use local information available with the node along with global network information to make a congestion control decision. We will also setup a DTN testbed for our research to verify the results produced by the simulator.

Research Topic:  Distributed and Resilient Cognitive Framework for Edge-centric IOT Applications

 

Abstract of the Research

Major drawback with the current frameworks revolving around IoT architectures is the increase in actuation time as the analysis of data happens on a central server. So there is a strong need to come up with truly scalable architectures and improved intelligent algorithms that can run on the edge devices. The focus of the research will primarily be on the distributed ML and process discovery resource-aware ML algorithms.
