본문내용

The number and variety of wireless devices and applications has dramatically increased
The need to provide communication between them is becoming important

In these ad hoc mobile networks
In an effort to establish and maintain routing paths,numerous unicast and multicast routing protocols have been designed
To determine the merits of the protocols,there have been investigations comparing the performance of these protocols (under various conditions and constraints)

This paper compared the performance of different ad hoc routing protocols
To determine whether the selection of the MAC layer effects the relative performance of ad hoc routing protocols

Wireless Routing Protocol (WRP)
Distance vector table-driven protocol

Maintain routing information through the exchange of triggered and periodic updates

If a node notice a link break with one
It broadcasts an update message(distance, second-to-last hoc information)
A neighboring node modifies its distance table entriesand checks for new paths through other nodes

A node successfully receiving an update message transmits an Ack back to the sender, indicating the link is still viable
