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...
Ant algorithm to search an optimal route of data transmission in the wireless sensor network was explored. There was introduced a limitation for the communication radius of the wireless unit that shorted a number of the search decision modes and improved the simulation accuracy of the wireless network. Correspondent software was designed and the dynamics and the decision search time was investigated...
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. As a result, the focus and effort of researchers is on designing better routing algorithms for a given application and network architecture of interest. Flat-based routing protocols have been...
In this work we design a virtual backbone to provide energy-efficient communication in Wireless Sensor Networks (WSNs). WSNs need virtual backbones to support in-network data transmission. In scenarios where there is no spatial redundancy (such as a sensor network in a petroleum installation), Connected Dominating Set (CDS)-based algorithms can be useful for hierarchical network management. We construct...
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...
