One of the important design issues of smart green buildings is to make use of energy, water and other resources efficiently. Improving the energy efficiency of buildings is an important step towards a more sustainable lifestyle, leading to significant cost savings for the residents. Wireless sensor network will be responsible for the majority of the growth in smart green building systems over the...
Directed diffusion protocol enables data-centric routing for smart home sensor network. However, traditional directed diffusion protocol makes all nodes participating in the routing process. This causes a lot of redundant data transmission which brings unnecessary energy consumption. In this paper, we proposed LDDP, a location-based directed diffusion routing protocol for smart home sensor network,...
Wireless sensor network routing protocol LEACH improves the energy efficiency with hierarchical topology structure, which exists shortages that less residual energy nodes are elected cluster head and that cluster heads directly communicate with base station. An energy balanced hierarchical routing algorithm (EBHRA) is proposed to improve disadvantages of LEACH. The EBHRA algorithm introduces residual...
New advancements in the technology of wireless sensors have contributed to the development of special protocols which are unique to sensor networks where minimal energy consumption is vital and very important.

Data transmission is one of the major challenges in wireless sensor network (WSN). Different routing protocols have been proposed to save energy during data transmission in WSN. Routing protocols based on data-centric approach are suitable in this context that performs in-network aggregation of data to yield energy saving data dissemination. In this paper we propose a modified version of SPIN protocol...
Rumor routing is a routing protocol based on query for wireless sensor networks, which selects next hop randomly during establishing path and the path may not be optimal and may be loop. So this paper puts forward a novel rumor routing (NRR), which bases on ant colony optimization and can resolve the loop route that established by rumor routing, and has good convergence, comparing to rumor routing,...
In order to tackle the energy hole problem of sensor networks, the non-uniform node deployment strategy was presented recently. For achieving the expected performance of this deployment method, nodes need to transmit data to the sink node through selecting a node in the adjacent inner-region decided by the deployment strategy. Since nodes near the outer-boundary of a region will be covered by more...
Due to the need of multiple monitoring applications in heavy haul railway transportation, applying the wireless sensor network into heavy haul combined trains is becoming a very popular topic. In this paper, an energy efficient transmission scheme based on cluster head election and power controlling (CHEPC) was proposed. In CHEPC, cluster head is periodically elected based on both energy and distance...
In this paper, we propose an Event-Driven wireless Sensor Network Multi-Path routing protocol (EDWSNMP), which includes three parts: multi-path creation, data communication and route maintenance. In multi-path creation part, a Heuristic Local Gabriel Graph (HLGG) algorithm is proposed to do topology control. In data communication part, cluster header collects data of other nodes in the cluster and...
In wireless sensor networks due to its strict resource constraints (with a lower energy, weak processing power), routing protocols should be simple and efficient as the goal, to maximize the extension of the life cycle of the entire wireless network. This paper presents a cross-layer optimization algorithm with the integration of MAC layer and routing layer to meet the requirements of energy-efficiency...
A good data transmission protocol should balance energy consumption, packets collision and some other factors well. The traditional layer protocol can't sufficiently meet the complex requirement of data transmission, so a cross-layer transmission protocol that is tree based power controlled (TBPC) is proposed. In TBPC, transmission power of regarded as a key factor, and it can be designed a series...
Recently, in order to improve the energy efficiency of WSN(Wireless Sensor Network), widely research have been carried on. But, up to the present, all presented methods are based on direct communication between CH (cluster head) and sink node, and based on the assumption that node can intelligent regulate signal energy according to the distance between nodes. So it's hard to implement those methods...
A wireless sensor network (WSN) is composed of a large number of sensor nodes which are resource constraints, e.g., limited power. This drives research on how to design routing protocols to gather data efficiently so that the life of the network can be prolonged. A usual concept to collect data by a sink node is to transfer data from sensor nodes to the sink node by multi-hop. However, it gives rise...
For wireless sensor networks (WSNs), how to design routing protocols is very important to gather data efficiently so that the life of the network can be prolonged. A usual concept to collect data by a sink node is to transfer data from sensor nodes to the sink node by multi-hop. However, it gives rise to two problems. The first one is the hotspot problem, in which the sensor nodes closer to the sink...
A wireless sensor network is a data communication system that consists of from several to thousands of tiny wireless sensor nodes.

To solve...
As many routing protocols for wireless sensor network canpsilat handle dynamic topological variation efficiently, a new hierarchical routing protocol (HTVRP) based on the shortest path is proposed. In this protocol, all of nodes are arranged to different logic layers according to their distance from the sink, thus a ring-hierarchy, tree-framework topology is formed. Each node merely communicates with...
