As the amount of digital data the world generates explodes, data centers and HPC systems that process this big data will require high bandwidth and high capacity main memory. Unfortunately, conventional memory technologies either provide high memory capacity (e.g., DDRx memory) or high bandwidth (GDDRx memory), but not both. Memory networks, which provide both high bandwidth and high capacity memory...
Assessing the basic parameters like received signal strength, packet delay, jitter, etc., for a network is a first step towards measuring the network performances. However, while selecting a network, one should consider multiple such attributes. In the existing literature, presence of more than one cellular network interface is typically not considered. Besides, the stability of the network is often...
Multipath remains a dominant source of error in satellite-based navigation, despite a great deal of effort by researchers and receiver manufacturers to reduce it. Mitigation of multipath errors is especially difficult when the Doppler shift between the direct and secondary propagation paths is very small (approximately 1-2 Hz) and this is usually the case in urban canyons where the reflectors are...
The network topology in Mobile Ad hoc Networks (MANETs) dynamically changes due to mobility of nodes and power constrained, hence routing is a challenging issue in these networks. QoS aware routing is needed to provide optimal routes as a function of parameters like bandwidth, delay, packet loss etc. Our approach is focused on QoS enabled route discovery procedure which involves estimation of node...
Mobile Ad hoc Networks (MANETs) are the networks of mobile nodes which do not require any access points to communicate with each other within the radio range. Due to their applications in situations such as emergencies, crisis management, military and healthcare, message security is of paramount importance in mobile ad-hoc networks. The paper proceeds with a brief introduction of MANETs followed by...
A novel completely inverter-based ADC driver is proposed that relaxes the gain and unity gain bandwidth requirements of the negative feedback loop by making it not see the closed loop gain. This ADC driver has a built-in first order anti alias filter and uses a passive amplifier to provide a rail-to-rail sampled output signal. This design exploits the linearity of current mirrors and achieves 65dB...
The paper presents the Performance Analysis of Manhattan Street Network (MSN). Improvement of performance at the destination node by applying different buffering capacities at the routers is demonstrated. The results using NS2 simulator are produced. It can be concluded that the congestion and the packet drops can be reduced at the link node by appropriate size of buffer at the link node.
