A novel eco-routing navigation strategy and energy consumption modeling approach for electric vehicles are presented in this work. Speed fluctuations and road network infrastructure have a large impact on vehicular energy consumption. Neglecting these effects may lead to large errors in eco-routing navigation, which could trivially select the route with the lowest average speed. We propose an energy...
Wireless sensor networks consist of hundreds or thousands of nodes with limited energy resources. Due to the high density of nodes in this kind of network, redundant data will be detected by nearby nodes. Since the network lifetime is a key issue in wireless sensor networks, in-network data aggregation can be exploited in order to reduce the number of messages exchanged and consequently reduce the...

In corona-based Wireless Sensor Networks (WSNs), nodes that are positioned in coronas near the sink drain their energy faster than others as they are burdened with relaying traffic come from distant coronas forming energy holes in the network. This situation shows significant effects on the network efficiency in terms of lifetime and energy consumption. The network may stop operation prematurely even...

Data gathering in an energy efficient and timely manner is the fundamental task of Wireless Sensor Network (WSN). The battery operated sensor nodes are of limited energy and it is necessary to preserve their battery power to elongate the lifetime of WSN. In Hierarchical Routing Protocol (HRP) some nodes transmit data to BS which is more energy intensive task while others are engaged in local communications...
Given the fact that LEACH protocol didn't take the residual energy of nodes into account when choosing the cluster heads, which may result in the node with rather low energy to be chosen as a cluster head. Thus, it will cause the cluster created by this low-energy node to be dead at an early stage, which wastes the whole network's resource. Here in this paper, we introduced an energy factor when choosing...

With the advent in technology and shrinking the transistor size down to nano scale, static power may become the dominant power component in Networks-on-Chip (NoCs). Powergating is an efficient technique to reduce the static power of under-utilized resources in different types of circuits. For NoC, routers are promising candidates for power gating, since they present high idle time. However, routers...
