hello sir
i want to write a source code for underwater acoustic sensor network energy model for my proposed routing protocol.... i just change that underwater scenario in MAODV protocol and proposed a new routing protocol....pls help me to give some suggestion to develope my protocol based on energy metrics...

The energy model represents the energy level of the nodes in the network. The energy model defined in a node has an initial value which is the energy level of the node at the beginning of the simulation. This energy is called the initial energy. In the simulation, the variable "energy" represents the energy level in a node at any specified time. The value of initialEnergy_ is passed as an input argument. A node loses a particular amount of energy for each transmitted packet and for each received packet. As a result, the initialEnergy_ value on a node is reduced. The energy consumption level of a node at any point in the simulation can be determined by finding the difference between the current energy value and the initial energy value. If a node's energy level reaches zero, it can not receive or transmit any more packets. The amount of power consumption in a node can be printed in the trace file. The energy level of a network can be determined by adding the energy level of the complete node in the network.

How to create power model in ns2 for MANET
In the wireless network, the power model is one of the optional attributes of a node. The energy model denotes the energy level in a mobile node. The components needed to design the power model include initialEnergy, txPower, rxPower and idlePower. The "initialEnergy" represents the energy level that the node has in the initial stage of the simulation. "TxPower" and "rxPower" denotes the energy consumed to transmit and receive packets. If the node is a sensor, the power model must include a special component called "sensePower". Denotes the energy consumed during the detection operation. The tcl script in sample7.tcl illustrates the wireless network power model with 3 nodes that are deployed in the 500m X 500m area. Each node is assigned to 10 Joules as "initialEnergy".
