RPL (Routing Protocol for Low-power and lossy networks) is a special? routing protocol designed for optimizing 6LoWPAN (IPv6 over Lower power Wireless Personal Area Network) operations. RPL suffers from resource constraints on battery, processor, memory and bandwidth, which make RPL more vulnerable to several threats than normal routing protocol. It is necessary to design a lightweight method to protect...
Topology control is one of core key factors which can influence performance of wireless-sensor networks (WSN). So how to design topology structure with high reliable and survivability is becoming the important subject on wireless-sensor networks. For the issue, a topology evolution strategy based on scale-free network with energy efficient is proposed. First by clustering algorithm cluster nodes are...
Network-on-Chips (NoCs) are becoming integral parts of modern microprocessors as the number of cores and modules integrated on a single chip continues to increase. Research and development of future NoC technology relies on accurate modeling and simulations to evaluate the performance impact and analyze the cost of novel NoC architectures. In this work, we present BookSim, a cycle-accurate simulator...
In this paper, we introduce notions of fuzzy delta-I-open Sets and fuzzy delta-I-continuous functions in fuzzy ideal topological spaces and investigate some of their properties. Additionally, we obtain a decomposition of fuzzy semi-I-continuous functions and alpha-I-Continuous functions by using fuzzy delta-I-continuous functions.
High Speed Downlink Packet Access (HSDPA) employed in 3G networks considerably augments wireless bandwidth, which enables a variety of mobile services based on TCP. However, the fundamental assumptions of TCP are disrupted by the properties hold by wireless network, such as high bit error rate, large delay and drastic bandwidth oscillation, which lead to the consequences of spurious time outs, spurious...
We numerically investigate the influence of the structural properties of small-world network on the traffic delivery, by adopting the shortest path routing policy. We focus on the network capacity that can be measured by the critical value of phase transition from free flow to congestion. Here we address influence of the topology on the dynamics of traffic delivery for small-world networks, taking...
