Sample text

The simplest mechanism for information dissemination within a network is Blind flooding. Blind flooding is used by routing protocols such as AODV [5] and DSR [6] to perform route discovery. Blind flooding may also be used in network management to distribute state information or in zero start auto-configuration. In Blind flooding, a node broadcasts a packet, which is received by its surrounding neighbours. Each receiving neighbour then verifies that it has not broadcast the packet before. If not, then the packet is rebroadcast.

2-10. Figure 2-9 shows average overhead per broadcast packet in bytes incurred by NAAP and MPR as the relay set is attached to each broadcast packet. In MPR the multipoint relay set may be distributed through beacon messages and therefore incurs overhead in beacon messages. In the simulation, we append the multipoint relay set to each packet prior to broadcast as done with source based MPR mechanisms [15]. RNG and LMSTFlood incure no additional overhead as each mechanism can determine independently whether or not to rebroadcast.

This combination makes up a truly dynamic system in the face of changing network topologies. We show that Calto scales well and thus can support a large number of nodes without introducing significant overhead. This chapter is organized as follows. In section 2 we describe the technologies that constitute the system. In section 3, we describe the Calto framework. Section 4 explains the presence information distribution protocols. Section 5 describes the search algorithm. In section 6 we describe how Calto networks are formed and updated.
