For saving energy and balancing the energy load among nodes, an energy-efficient data gathering algorithm (EDGA) based on clustering is proposed in this paper, which is used to gather data in wireless sensor networks. Firstly, the nodes compete for becoming a clusterhead according to residual energy and the distribution of neighbor nodes. Secondly, the clusterhead selects the active nodes according...
For monitoring burst events in a kind of reactive wireless sensor networks (WSNs), a novel scheme of dynamic clustering routing algorithm (DCRA) based on support degree is proposed. The new approach lets sensors decide whether become a clusterhead (CH) according to the support degree coming from neighbors. Unlike traditional distributed clustering algorithms, DCRA combines energy, load balancing and...
In wireless sensor networks, energy is scarce resource such that its conservation and efficient use is a major issue. Therefore, a key goal of routing design in WSNs is to save energy and at the mean time increase the network lifetime. In this paper, we propose an on-demand multipath routing algorithm from the viewpoint of probability, named MRAP. The goal of MRAP is to balance the energy consumption...
These nodes have limited energy supply in wireless sensor networks. Thus energy consumption is the main concern while developing routing algorithm in wireless sensor networks. In this paper, we propose a multi-path routing algorithm based on Rumor Routing, called EBMRR (Energy-Balance Multipath Rumor Routing), which is probabilistic approach that attempts to find multipath according to residual energy...
The energy constraint sensor nodes operate on limited batteries, so the energy consumption is a key design criterion for the routing protocols in wireless sensor networks. Comparing with single path routing algorithm, multi-path routing algorithm can balance the network energy distribution and extend the network lifetime better. In this paper, we propose an Ant Colony- Based Multi-path Routing Algorithm,...
In this paper, we propose an iterative area/performance tradeoff algorithm for look-up table (LUT)-based field programmable gate array (FPGA) technology mapping. First, it finds an area-optimized, performance-considered initial network by a modified area optimization technique. Then, an iterative algorithm consisting of several resynthesizing techniques is applied to trade the area for the performance...
