The Simulation and Implementation of Sensor
Networks’ Effective Working Life
Abstract
Sensor networks are contemporary international issue of great concern , It can be widely used in the military, transportation, environmental monitoring and forecasting, health, space exploration and other fields. As each sensor' energy load is limited,and it is difficult to add energy, how to extend the life of sensor networks becomes aney issue. The so-called sensor networks' effective work life in this paper is the span of the first sensor node that deplets its energy. There are other explainations of networks’ effective working life,this paper will introduce them one by one.
Sensor networks' actual work environment is not easy to the ideal state, and the actual work environment is very difficult to control to the perfection artificial . So this paper firstly introduces network simulation, and the main network simulator. This paper give Sensor networks' definition of life as well as research of routing algorithm . Considering wireless sensor networks'characteristics of the transmitting and routing issues, obtian a more efficient algorithm.It introduces network simulation tools' installation, configuration and using of the tcl,otcl, tclcl script language and makes practice of network simulator. After simulating wsn routing protocol it adds new protocol to it , and implements the sensor network' Single-hop and multi-hop routing protocolon the energy unbalance simulation. Based on energy research and simulation, proposes a new assumptions of the energy consumption , that the combination the advantages of multi-hop and single-hop to extend the life of sensor networks.
