A newly proposed Double Latch Pre-charge Sense Amplifier (DLPSA) is introduced in the embedded non- volatile memory design for the wireless application, especially for smart cards with wireless & contactless feature, e.g., bank cards (wireless credit cards). This DLPSA has been implemented in both SMIC 0.18im and 0.13im process of ROM IPs. Comparing with the conventional sense amplifier, DLPSA...
Distributed simulation techniques are commonly used to improve the speed and scalability of wireless sensor network simulators. However, accurate simulations of dynamic interactions of sensor network applications incur large synchronization overheads and severely limit the performance of existing distributed simulators. In this paper, we present two novel techniques that significantly reduce such...
In this paper, we present a Distributed Geography-based Fault Tolerant topology control algorithm (DGFT) for static large-scale wireless sensor networks. We introduce the scale-free characteristic of complex networks into the topology of large- scale wireless sensor networks to obtain robustness and time efficiency. DGFT enables wireless nodes to define the topology by neighbor relationship, based...
In this paper, we propose an efficient and fault tolerant topology control algorithm named AWSF for large-scale wireless sensor networks, which introduces the scale-free characteristic of complex networks into the topology of wireless sensor networks to minimize transmission delay and increase robustness. It is a distributed algorithm, letting each node locally adjust its transmission power and determine...
