Routing protocol is one of the most important methods to reduce and balance energy consumption in Wireless Sensor Network. Three schemes are proposed in this paper aiming to reduce nodes' energy consumption and extend the lifetime of the network, including communication distance minimization, substitutable nodes sleeping and child nodes balancing. At last, simulation and analysis is given, which shows...
Using routing algorithm to reduce nodes' energy consumption and prolong the networks' lifetime is one of research emphasis for Wireless Sensor Networks. Based on vegetable shed, a wireless network is building and a hierarchical routing algorithm is proposed by nodes' geographical information and communication layer information. Firstly, the different layer is divided by nodes' communication layer...
Owing to the limited resources of the sensor nodes, energy-efficient routing mechanism becomes one of the most important technologies in wireless sensor networks. As an active branch of routing technology, cluster-based routing protocols excel in network topology management, energy minimization, data aggregation and so on. In this paper, cluster-based routing mechanisms for wireless sensor networks...
In this paper, a novel Uneven Cirque energy-balance Clustering Routing for sensor networks (UCCR) was proposed. UCCR import energy forecasting mechanism, according to the residual energy of node to determine when to re-cluster. Cluster head is chosen based on the residual energy and the relative position. Multi-hop data routing was formed in inter-cluster, routing to build not only consider the energy...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
