end points in the network. This did not support for interconnection heterogeneous network. Our focus is mainly on this part and creates a simple scenario in NS2 by using AODV protocol.

The second argument is on the SCTP implementation in the Multihoming Network, it is not an independent protocol. When it is functioning all the time it requests to use some other protocols. Example: Other Transport layer protocols.

The last argument is the support of the SCTP [5] is very poor in the Moblie Adhoc Network. Especially in the sensor network, where the transport verification is not so important, UDP need to be used instead of TCP for the power consumption. But SCTP is not functioning like that.

Because of all these reasons I have ignored the Steam Control transmission Protocol (SCTP) and implemented scenarios for Multihoming network by using CMU Monach group NS2 and the concepts. Basically the below idea is used in my arguments. There are four nodes using for this implementation.

Node1 and the Node2 in one network channel and Node3 and Node4 in another network channel. The packets can't send from Node1 to Node4. Because the Node1, Node2 in one channel or the network and Node2, Node3 in another channel or the network. Once the packets want to send the data from Node1 to Node4 the Node 2 and Node 3 should be configured as a bridge between these two network channels. Further more details check the figure 01 below.

Channel 1 Channel2

A.Simulation codes and set up analyisis
Implemented AODV protocol in define option instead of SCTP protocol.

set val(rp) AODV ;# routing protocol

In NS2 :

Phy/WirelessPhy set Pt ;#is for sender side,

Phy/WirelessPhy set RXThresh ;#is for receiver side

Below the commands use to be set the parameters make the transmission range 250m for two-ray ground signal propagation model.

Phy/WirelessPhy set RXThresh_ 3.65262e-10

Phy/WirelessPhy set Pt_ 0.281838

Phy/WirelessPhy set freq_ 914e+6

Create God.

set god_ [create-god val(nn)]

Configure phenomenon channel and data channel

set chan_0_ [new val(chan)]

set chan_1_ [new val(chan)]

set chan_2_ [new val(chan)]

The below command use to configure Node1 and Node2 in channel-1.

ns_ node-config \

-channel chan_1_

set node_(1) [ns_ node]

node_(1) random-motion 0 ;# disable it(random-motion)

god_ new_node node_(1)

node_(1) set X_ 40

node_(1) set Y_ 50

set node_(2) [ns_ node]

node_(2) random-motion 0;# disable it.

god_ new_node node_(2)

node_(2) set X_ 50

node_(2) set Y_ 50

As same as above command, the commands below use to configure Node3 and Node4 in channel-2

ns_ node-config \

-channel chan_2_

set node_(3) [ns_ node]

node_(3) random-motion 0 ;# disable it.

god_ new_node node_(3)

node_(3) set X_ 50

node_(3) set Y_ 50

set node_(4) [ns_ node]
