Networks RG

Introduction

Network Research Group is focusing on broadband wireless and mobile networks. The issues of interest include mobility management, quality of service (QoS), radio resource allocation and performance evaluation in diverse wireless networks such as 3G/4G cellular, WLANs, WiMaX, Wireless Mesh, UWB, ZigBee and Bluetooth. The major emphasis is on protocol design, development and optimization. The research work is carried out using both analytical and mathematical modelling (Queuing Theory, Game theory, etc) and simulation modelling (OPNET, ns-2, OMNET++, MATLAB, etc).

Research Facilities

Research Facilities are currently being setup which include two labs that are essential for supporting graduate programs, promoting research and provide certification training to meet the growing needs of trained and skilled human resource in the area of networks.

Broadband and Wireless Networks Lab

  • focusing on high-speed networking infrastructures, access technologies and protocols
  • Mobile Computing Lab
  • focusing on applications and middleware

The equipment required for these labs include routers, gateway, switches, access points, servers, PCs, laptops, handheld devices, traffic generators, packet analyzers, channel emulation and performance monitoring and analysis tools. The software tools needed include simulators such as OPNET, ns-2, OMNET++, Glomosim and NTNS, traffic analyzers such as WireShark, load generators like TCPgen, UDPgen, RF planning tools, RF optimization and channel emulation software and various application development of SDKs (Symbian, J2ME, WindowsCE, Embedded Linux).
