Geographic routing is one of the most widely used routing strategies in large-scale wireless sensor networks (WSN). With location-based routing, small, cheap and resource constrained nodes can perform the routing function without the need of complex computations and large amount of memory space. In the traditional approach, nodes advertise their availability to update the routing table. We eliminate...
Indoor Wireless sensor networks require a highly dynamic, adaptive routing scheme to deal with the high rate of topology changes due to fading of indoor wireless channels. Besides that, energy consumption rate needs to be consistently distributed among sensor nodes and efficient utilization of battery power is essential. If only the link reliability metric is considered in the routing scheme, it may...
The success of various sensor network applications highly depends on the use of energy-conserving routing methods to prolong network lifetime. We present a heterogeneous sensor network architecture consisting of a small number of high-end sensors serving as sink nodes and a large number of low-end sensors responsible for environmental sensing. We propose a path bottleneck-oriented and energy cost-based...
The primary energy and balance of energy consumption of wireless sensor networks (WSNs) plays a key role in network lifetime and stability. However, the energy of each node and the total energy in wireless sensor networks are limited. In this paper, an efficient energy cluster-based routing protocol (EECRP) for wireless sensor network is presented and its properties are investigated. Its core is that...
Wireless sensor networks (WSN) consists of tiny autonomous devices called sensors capable of sensing, processing and transmitting information. Energy consumption, routing and maximizing lifetime are the important challenges in the sensor network. In this paper, we propose multiple tree construction (MTC) algorithm to address the problem of finding path from each node to its nearest base stations to...
In wireless sensor networks, energy-balanced data propagation is crucial to achieving satisfactory network lifetime. This paper presents a probability-based mathematical model to formulate the energy dissipated by data transmission of sensor nodes for arbitrary network topology. The mathematical model summarizes an extensive design space for routing, in which direct transmission and minimum transmission...
Cluster-based routing scheme is able to prolong the network lifetime and save the energy consumption. In this field, many cluster-based routing protocols are proposed such as LEACH, TEEN, APTEEN, and so on. On the other hand, the chain-based routing protocols construct the chain such as PEGASIS and concentric-clustering routing scheme. The concentric-clustering routing scheme is the multiple-chain...
