Load-based Clustering for Hierarchical Routing

نویسنده

  • Beat Liver
چکیده

A novel abstraction of the available bandwidth in a communication network is presented based on the blocking island abstraction (Frei & Faltings 1997). Path computing algorithms using this abstraction are presented for non-hierarchical and hierarchical networks. For the latter case, a composeable abstraction of subnetworks is proposed.

MLCA: A Multi-Level Clustering Algorithm for Routing in Wireless Sensor Networks

Energy constraint is the biggest challenge in wireless sensor networks because the power supply of each sensor node is a battery that is not rechargeable or replaceable due to the applications of these networks. One of the successful methods for saving energy in these networks is clustering. It has caused that cluster-based routing algorithms are successful routing algorithm for these networks....

Choosing the Best Hierarchical Clustering Technique Based on Principal Components Analysis for Suspended Sediment Load Estimation

1- INTRODUCTION The assessment of watershed sediment load is necessary for controling soil erosion and reducing the potential of sediment production. Different estimates of sediment amounts along with the lack of long-term measurements limits the accessibility to reliable data series of erosion rate and sediment yield. Therefore, the observed data of suspended sediment load could be used to ...

Attribute Based Hierarchical Clustering in Wireless Sensor Networks∗

Data routing in large wireless sensor networks face the challenge of delivering data over a network in which the nodes may not have globally unique identifiers, must satisfy stringent energy saving requirements and be highly scalable and fault tolerant. In addition, if the sensor network becomes a resource shared by members of a large user community (a likely event in the future), then the rout...

Energy Efficient Zone Division Multihop Hierarchical Clustering Algorithm for Load Balancing in Wireless Sensor Network

Wireless sensor nodes are use most embedded computing application. Multihop cluster hierarchy has been presented for large wireless sensor networks (WSNs) that can provide scalable routing, data aggregation, and querying. The energy consumption rate for sensors in a WSN varies greatly based on the protocols the sensors use for communications. In this paper we present a cluster based routing alg...

Dynamic Hierarchical Energy-Efficient Method Based on Combinatorial Optimization for Wireless Sensor Networks

Routing protocols based on topology control are significantly important for improving network longevity in wireless sensor networks (WSNs). Traditionally, some WSN routing protocols distribute uneven network traffic load to sensor nodes, which is not optimal for improving network longevity. Differently to conventional WSN routing protocols, we propose a dynamic hierarchical protocol based on co...
