However,for this minimum-transmission-energy (MTE)
routing protocol,rather than just one (high-energy) transmit
of the data,each data message must go through n (lowenergy)
transmits and n receives.Depending on the relative
costs of the transmit amplifier and the radio electronics,
the total energy expended in the system might actually be
greater using MTE routing than direct transmission to the
base station.
Using Equations 1 - 6 and the random 100-node network
shown in Figure 3,we simulated transmission of data from
every node to the base station (located 100 m from the closest
sensor node,at (x=0,y=-100)) usingMATLAB.Figure 4
shows the total energy expended in the system as the network
diameter increases from 10 m \2 10 m to 100 m \2 100
m and the energy expended in the radio electronics (i.e.,
Eelec) increases from 10 nJ/bit to 100 nJ/bit,for the scenario
where each node has a 2000-bit data packet to send to
the base station.This shows that,as predicted by our analysis
above,when transmission energy is on the same order
as receive energy,which occurs when transmission distance
is short and/or the radio electronics energy is high,direct
transmission is more energy-efficient on a global scale than
MTE routing.Thus the most energy-efficient protocol to
use depends on the network topology and radio parameters
of the system.
