Communication and Internet Research Lab

Basic research in order to understand the dynamics of transport layer protocols in the context of mobile wireless environment of an All-IP converged network.
To understand characteristics of access networks and mobility pattern of the Internet enabled devices.
To come up with heuristics that could be applied to the design of algorithms capable of learning and reacting to the heterogeneous and dynamic nature of the network.
The findings could be applied to improve the performance of transport service, and to develop an intelligent and adaptive transport layer protocol that is reactive to changing network characteristics.

IP Mobility and beyond

We are conducting investigation and research to better understand IP mobility in the context of next generation "all IP" wireless networks.
Investigations into micromobility issues in such "all IPnetworks, which addresses the localized mobility management and propose, design and implement protocols to provide micromobility management.
Investigations into the various handoff and location management schemes for mobile environments.
The Communication and Internet Research Lab testbed presently is fully IPv6 enabled, and a Mobile IPv6 testbed has been set-up, providing excellent research infrastructure.
A solution (U.S patent pending) has been developed at CiRL, that provides a seamless transition mechanism from the present IPv4 protocol to IPv6. An IPv6 based micromobility protocol called AUM (Auto-update Micromobility Protocol) has also been proposed.

Mobile Ad-Hoc Networks (MANETs)

To design efficient stability based routing protocols for MANETs
Research on provisioning Quality of Service, models and mechanisms, in MANETs. Providing complete QoS solution requires the interaction and co-operation of several components like routing protocol, resource reservation and medium access control protocol. Research also focuses on various Inter-Layer interactions.
Secure communication in MANETS is critical and even unavoidable for most of the applications. Research on security in MANETs encompasses following challenges: availability, confidentiality, integrity, authenticity, and non-repudiation.
Majority of performance analysis work is carried out with either simulations or real-time experiments.

Wireless Sensor Networks

To investigate and research on many challenging problems in wireless sensor networks: data aggregation/collection, tasking and control, routing, topology control, etc.
To implement and build real-world wireless sensor systems: temperature sensor networks, RFID inventory management, people management, and possibly many more.
Research on wireless sensor network management framework. To come out with a general architecture that supports many different types of sensor network management
