3.1 Scalability of Protocols
The term scalability means that the number of users and/or the traffic volume can be increased with rea-
sonably small performance degradation or even net- work outage and without changing the system compo- nents and

The GeoGRID [Liao et al., 2000] protocol is also for geocast. It is modified from the GRID protocol. As mentioned earlier, the GRID protocol divides the network area into several nonoverlapping squares called grids. Geocasting messages are sent in a grid-by-grid manner through grid leaders. However,[r]

When you think of applying distributed TC in practical settings, you have to face several problems, mainly because of the fact that some (or many) of the assumptions on which the protocol design is based may not hold. One such striking example is the assumption that all the nodes have the same maxim[r]

3.5.1 Simulation 1. Simple Topology
Using the simple scenario in Fig 3.1 , we illustrate how DCAR is vulnerable to flow-arrival times and how our proposed protocol SCAR can withstand this variability. We start with a flow from node 1 to node 2, and then, add a new flow from node

Low mobility was simulated to represent close to a best case scenario, where the nodes do not lose links very frequently. This case can be used to demonstrate an upper bound on en- ergy savings in an ad hoc wireless environment. Low mobil- ity[r]

WIRELESS ATM AND AD HOC ROUTING
In WRP, nodes exchange update messages with their neighbors both periodically and as a result of link changes. Such is the case of a link loss between two nodes, e.g. A and B. In such cases, A and B send update information to their neighbors, which in turn modify their tables
