Optimum bi-level hierarchical clustering for wireless mobile tracking systems

Hierarchical Interface - based Supervisory Control : Bi - level Systems

In this report we present a hierarchical method that decomposes a system into a high level subsystem which communicates with n ≥ 1 parallel low level subsystems through separate interfaces, which restrict the interaction of the subsystems. We first define the setting for the serial case (n = 1), and then generalise it for n ≥ 1. We present a definition for an interface, and define a set of inte...

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....

Mobile Speed Estimation for Hierarchical Wireless Network

Hierarchical Mobile Wireless Network (HMWN)*

Ad hoc networks may not be suitable for “non ad hoc” applications due to resource, mobility, traffic pattern and incompatible wireless MAC protocols issues. We propose the Hierarchical Mobile Wireless Network for providing flexible and scalable network services to these applications. In such a system, mobile hosts are organized into hierarchical groups. Four basic operations that are used to se...

Adaptive Clustering for Mobile Wireless Networks

This paper describes a self-organizing, multihop, mobile radio network, which relies on a code division access scheme for multimedia support. In the proposed network architecture, nodes are organized into nonoverlapping clusters. The clusters are independently controlled and are dynamically reconfigured as nodes move. This network architecture has three main advantages. First, it provides spati...
