Whenever streaming of multimedia based data such as video, audio and text is performed traffic will be more and network becomes congested in mobile ad hoc networks. The present routing protocols are not able to cope up with this situation. It is observed that network congestion is the dominant reason for packet loss, longer delay and delay jitter in(More)
Breadth First Search Channel Assignment(BFSCA) is a hybrid channel assignment algorithm that utilize multiple radio interfaces to improve the throughput and minimize the interference within the wireless mesh network and between the mesh network and co-located wireless mesh networks. This new channel assignment scheme allows different nodes in the same(More)
In mobile ad hoc networks, most of the present routing protocols are designed to have congestion aware, but not congestion adaptive. The way in which the congestion is handled results in longer delay and more packets to be lost for streaming multimedia. When a new route is needed, the routing protocols require a significant overhead in finding it. Mobile Ad(More)
Transmission Control Protocol is commonly used communication protocol. Congestion Control is one of the hardest problems in robust networked systems. Throughput is a measured performance metric in all communication systems. Many TCP variants play an important role in controlling the congestion. TCP New-Reno works comparatively better when congestion is more(More)
This paper proposes a reconfigurable parallel architecture for space-borne on-board processing that combines the advantages of powerful computational resources with a straightforward software development. This approach introduces the concept of software payloads that enable the users the direct transfer of their ground-based applications towards space and(More)
The prediction of bit error rate (BER) in IEEE 802.16e mobile wireless MAN network is investigated here. The state of the channel is estimated on symbol by symbol basis on a realistic fading environment. The state of a channel is modeled as nonlinear and temporal system. Neural network method is the best system to predict and analyze the behaviors of such(More)
In the communication era congestion is the bottleneck which degrades the performance. In Ad hoc networks due to infrastructure less character there is no guaranteed bandwidth and node mobility. The traditional TCP variants were good for wired environment, whereas in Ad-hoc networks there are lots of other factors to be considered. We are comparing the(More)
In today's world many are faced with issues relating to security in Mobile Adhoc networks and areas of its application like wireless internet information system deployed in international borders, collection of sensor data for, Air pollution monitoring or for emergency response system in indoor environment. The present study deals with a novel approach of(More)
The rapid growth in wireless networking has brought a number of security concerns to the service providers and end users. Security, Authentication, Encryption and Access Control are the vital features that must be presented in any communication network. One of the principal reasons that security is such a significant issue in cellular system because they(More)
Wireless cellular network has recently emerged as one of the popular technologies for the next generation network due to the development of smart phone technologies which resulted in high mobility of user and achieving Quality of Service (QoS) for application like video conferencing, video streaming etc... requires an efficient multicast routing protocol(More)
