A traffic distribution in a wireless network plays a major role in resource allocation. In this paper, we analyze throughput in Cognitive Radio Network (CRN) under two traffic distributions Pareto on-off and Poisson distribution. We consider a CRN where the cell is divided into different concrete circles and sectors. In each segment is analyzed and the channel is allocated accordingly while taking...
In wireless ad hoc networks, Quality of Service (QoS) can be obtained efficiently using the power control scheme. Power control can be achieved by incorporating cooperation among the available links. In this paper, we propose an adaptive pricing scheme that enables the nodes in the networks to determine the maximum allowable power that can be used for transmission of data within the networks so as...
In Cognitive Radio network, the Secondary Users (SU) makes use of the spectrum of licensed primary user when they are unoccupied. Here we have studied and expressed the normalized throughput for both single secondary user and multiple secondary users coexisting under cooperative sensing technique. We have also incorporated the consequences due to imperfect sensing and analyzed the throughput under...
Modern data center networks (DCNs) often use multi-rooted topologies, which offer multipath capability, for increased bandwidth and fault tolerance. However, traditional routing algorithms for the Internet have no or limited support for multipath routing, and cannot fully utilize available bandwidth in such DCNs. As a result, they route all the traffic through a single path, and thus form congestion...
