Title : Application Of Live Streaming Video In Multimedia Technology  

Author Name : Saranya. M

Synopsis :  

Streaming video from the server is being an everlasting problem for all of us till now. The videos cannot be seen from the server so easily by the user. The user has to wait for the videos to buffer, which is the streaming process. If more than two persons are watching the same video at the same time, user may face so much of buffering problem, clarity in the video content also. The problem occurs because each individual user does not have their individual path to the server, which they use. This problem can be overcome by the concept of subway tunnel. “Subway tunnel” which means that a secondary path is created to the user from the server they use. So if the bandwidth of the user’s path cannot withstand with the content, the user can take the subway path to transfer the video content. Bit streaming method is used for streaming the video content from the server. This method helps us to stream the video content without any loss in the content of the video & quality. By this way the users (i.e., multiple users) can able to overcome the problem of streaming videos from the server.

Title : Bit Error Rate (BER) performance analysis of DSSS-FEC coherent and non-coherent MFSK under Rayleigh and Rician fading channels

Synopsis : 

Forward Error Correction is an efficient technique to correct, preferably burst errors, caused over several blocks of transmitted data. Besides this, narrowband interference (NBI) is an unavoidable major cause for transmission errors in wireless communication, which is much severe in unlicensed band like ISM band. It is needed to spread the encoded data before being modulated to overcome both burst errors and interference. Direct Sequence Spread Spectrum (DSSS) is a good support for wireless networks with nodes preferred to consume less power due to its less implementation complexity. This paper is the simulated comparative analysis of BER performance of FEC coded coherent and non-coherent M-ary FSK under the impact of both Rayleigh and Rician fading channels. BCH, RS, Cyclic and Linear Block codes are used in this simulation. Simulation results show that, RS Encoder – Decoder pair gives good BER performance over Rayleigh fading channel, especially with integer inputs and its performance should be enhanced for Rician fading channel.

Synopsis :  

 

Potential use of wireless sensor networks (WSNs) can be seen in various fields like disaster management, battle field surveillance and border security surveillance since last few years. In such applications, a large number of sensor nodes are deployed, which are often unattended and work autonomously. Clustering is a key technique used to extend the lifetime of a sensor network by reducing energy consumption. It can also increase network scalability. Researchers in all fields of wireless sensor network believe that nodes are homogeneous, but some nodes may be of different energy to prolong the lifetime of a WSN and its reliability. In this paper an attempt is made to calculate energy required for all the nodes to be placed in the network in the same structure as was defined under MSMTP protocol in bottom up fashion i.e. energy of all nodes is initialized to zero & after each round transmission & receiving energy required is added to energy of each node. After completing certain number of rounds required energy of each node can be deduced.

Title : HARAQ-Routing Table for On-Chip Congestion Control  

Author Name : swetha priyanka, G Rajesh  

Synopsis : 

When the Message latency increases in Networks-On-Chip Performance of the channel decreases due to congestion. In Mesh topology, minimal methods can distribute messages over two directions at each switch, but in high traffic loads this methods are inefficient. We present a non-minimal methods can overcome this blocking problem in high traffic loads and reduce the waiting time of messages by delivering them via alternative paths called HARAQ.To avoid creating cycles in network, the algorithm define all allowed turns including 180-degree turns on a single channel. To select a less congestion path from output channel to the destination region based on local and global information in the learning method.

Title : Balanced Energy Consumption Approach For Deployment Of Clusters In A WSN  

Author Name : Debajyoti Pal 

Synopsis :  

In this paper we aim to deploy the clusters of a Wireless Sensor Network in such a way so that it leads to a balanced energy consumption. First, we discuss about the radio energy dissipation model [1] that is already in place and the corresponding protocols which are used. Thereafter, we focus on the protocols which are already in practice in such a system, outlining their major disadvantages. Later on, we propose a methodology/algorithm that improves the overall energy consumption which is supported by the results of the experiments carried out by the simulations. Finally, a comparative analysis is done over the results obtained by our algorithm and those which existed previously
