THESIS: June 2010 - Present

Study of priority-aware error resilient JM H.264 AVC video compression for wireless transmission

• A systematic study of loss patterns in JM H.264 AVC. The effect of loss of different types of frames is being studied.

• The error resilience type FMO is used to give protection to the slices of the sequence. Dispersed FMO type has been used for the simulations. Where in the slices of the sequence are divide into two slice groups.

• PSNR (Peak Signal to Noise ratio) and VQM (Video Quality measurement) are the two parameters considered for the measurement of the quality of the video.

• Perl scripting was used for automation.

Scalable video coding (SVC) in JSVM:

• As part of the research, I studied Quality scalability in SVC.

• With the help of MGS, we can divide a single layer coding into different quality layers. The difference in the bit rate between the quality layers can be used to create different bitrates by dropping the difference bits in the quality layers in AVC.

• The SVC PSNR is always better than the AVC PSNR because of the scalability in SVC. To get the AVC results closer to SVC, the drop pattern has to be studied. The aim is to achieve less PSNR drop by losing more bits.

Design a high speed network

The goal of this project was to design a high speed wireless networking protocol that will compete with the new 802.11n standard. Specifically, to differentiate our protocol from 802.11n, it must offer the following services at the MAC layer:

• The network must carry isochronous as well as asynchronous transmissions.

• The network must ensure quality of service asynchronous traffic with 4 priority levels.

• A node must be able to transmit traffic directly to a peer, without passing the data through an access point.

• Multicast, which is a default for isochronous traffic, must also be supported for asynchronous traffic.

Scalable video coding in H.264

• The aim of the project was to study different types of scalable coding using JSVM software for different network specifications.

• Simulations for all the types of scalable were run for different sequences to get a better idea on SVC.

Tools: JSVM

Wireless sensor networks: Design a single hop network

• To design and implement a single hop wireless ad-hoc network using TinyOS platform.

• The network will have two possible nodes: gateway node and the end node.

• The gateway node send invitation signals every second and the end node sends the join request when it hears these invitation signals.

• The gateway node should ignore the signal from any other nodes and should only accept the signal from the end node.

Design a multi-hop network

• This project was a Multi hop wireless sensor network that consists of a Root node (Gateway) and the sensor nodes (end nodes) which will report the data to the root node.

• The root node acts as a sink and it also assigns the network ids to other sensor nodes. Any node can start to form its own network. All the nodes including root is allowed to have only two children.
