Detailed Description

Basic UAN channel class.

This is a simple channel class. It keeps a list of nodes using STL list, and computes propagation distance to nodes using 1500 m/s instead of the speed of light. The main departure with the standard NS2 channel class is that this node sets the RxPr member of txinfo before sending a packet up to the phy layer.

This class depends on a UanPropagation class being linked to it in the NS2 TCL

Note:

Requires UAN Physical layers and a UAN propagation class

Member Function Documentation

void UanChannel::sendUp	(	Packet *	p,
		Phy *	txif
	)			[protected, virtual]

Sends packet *p from interface txif up to all nodes in nodeList.

Parameters:

	p	Pointer to packet to send
	txif	Pointer to sending UanPhy based interface

Sends packet to all nodes regardless of range. Computes RxPr before and adds to the p->txinfo_ struct before sending node to phy.

Reimplemented in UanChannelBhp.

double UanChannel::get_pdelay	(	Node *	tnode,
		Node *	rnode
	)			[protected, virtual]

Computes propagation delay between tnode and rnode.

Parameters:

	tnode	Pointer to MobileNode class of transmitting node
	rnode	Pointer to MobileNode class of receiving node

Uses speed of sound in seawater of 1500 m/s
