Aqusim (Under Water Sensor Network) in ns2
Overview:
Aqua-Sim can effectively simulate acoustic signal attenuation and packet collisions in underwater sensor networks. Moreover, Aqua-Sim supports three-dimensional deployment. Further, Aqua-Sim can easily be integrated with the existing codes in NS-2. Aqua-Sim is in parallel with the CMU wireless simulation package. As shown in the figure below, Aqua-Sim is independent of the wireless simulation package and is not affected by any change in the wireless package. On the other hand, any change to Aqua-Sim is also confined to itself and does not have any impact on other packages in NS-2. In this way, Aqua-Sim can evolve independently.
Advantages of Aqua-Sim
- Discrete-event driven network simulator
- Support 3D networks and mobile networks
- Simulate underwater acoustic channels with high fidelity
- Implement a complete protocol stack from physical layer to application layer

OBS Network in NS2
Optical Burst Switching (OBS) is an optical network technology that aims to improve the use of optical networks resources when compared to optical circuit switching (OCS). OBS is implemented using Wavelength Division Multiplexing (WDM), a data transmission technology that transmits data in an optical fibre by establishing several channels, each channel corresponding to a specific light wavelength.
Optical Burst Switching is used in core networks, and viewed as a feasible compromise between the existing Optical Circuit Switching (OCS) and the yet not viable Optical Packet Switching (OPS).
In OBS, packets are aggregated into data bursts at the edge of the network to form the data payload
Techopedia explains Optical Burst Switching (OBS)
Optical Burst Switching has several distinctive features: first, the packets are aggregated in the ingress (entry) node, for a very short period of time. This allows that packets that have the same
constraints, e.g., the same destination address and maybe, the same quality of service requirements are sent together as a burst of data (therefore the term Burst in the concept name). When the burst arrives at the egress (exit) node, it is disassembled and its constituent packets routed to their destination.
While the burst is being assembled in the ingress node, or possibly, after the burst has been assembled, a control packet (or header packet), containing the routing information for that burst is sent to the network, ahead of the burst. The time that separates the transmission of the control packet and the transmission of the burst is termed the offset time, and it must be long enough to allow all the routers in the predicted path the burst will take, to be configured, and only for the time needed for the burst to cross the network. When the network nodes are configured, the burst departs the ingress node and travels through the network in an all-optical form, using the circuit that was previously established by the control packet.
The second characteristic of OBS is that the routing information is transmitted in the Control Packet and is not part of the data burst itself. In fact, the burst crosses the intermediate nodes in the
network using the pre-established and pre-configured circuit in an agnostic manner, i.e., the node does not need to interpreted the data in the burst, and so, it does not need to know the format of the data in the burst. This is another special feature of OBS.
Another distinctive characteristic of OBS is that the Control Packet will undergo optical to electronic to optical conversion at each intermediate node, and also optical to electronic conversion at the egress node, as to allow these nodes to be able to configure its optical switching devices. A final characteristic of OBS networks is that there is what is called a data and control plane separation, i.e., the channel that is used to transmit the control packets is specific and different from the channels that are used to transmit the data bursts.

IPV6 (Internet Protocol version 6) in NS2
Introduction:
Internet Protocol version 6 (IPv6) is the latest version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion.
IPv4 Vs IPV6:
On the Internet, data is transmitted in the form of network packets. IPv6 specifies a new packet format, designed to minimize packet header processing by routers. Because the headers of IPv4 packets and IPv6 packets are significantly different, the two protocols are not interoperable. However, in most respects, IPv6 is a conservative extension of IPv4. Most transport and application-layer protocols need little or no change to operate over IPv6; exceptions are application protocols that embed internet-layer addresses, such as FTP and NTPv3, where the new address format may cause conflicts with existing protocol syntax.

Handoff in ns2 (Handoff between Wlan and UMTS networks)
Vertical Handoff means handoff is between two network access points or Base Stations that uses the different network access technologies.
Steps of Vertical Handoff
1.System Discovery:
2. Handoff decision:
3. Handoff execution:
1. Available Bandwidth (BAV): It is the amount of unused bandwidth of the candidate Base Station (BS) or Access point (AP).WLAN have greater bandwidth than cellular Network (UMTS).
2. Speed of mobile terminal (VMT ): It is the velocity with which the mobile terminal (MT) is moving. For high speed MT, UMTS is preferred because of greater coverage area.
3. Number of Users (UN): The QoS of WLAN is UN sensitive. As the number of users increase, the collisions increase and results in poor QoS.
4. Received Signal Strength (RSS): It is the strength of the signal received, as the RSS of the neighboring network rises above the threshold the Vertical Handoff is feasible i.e. the handoff takes place if and only if RSS of the BS or AP is above the threshold.
