protocols for wireless ad hoc networks. The service
discovery mechanisms are integrated with routing
protocols to reduce the overhead.
Service Announcement:
Service announce-
ment is a basic mechanism for services to inform
clients, peer services, and directories their up to
date information. Services usually have life spans
and will be invalid after the life span. Services
use the service announcements to notify interested
parties that they are available.
Service Attribute:
Service attributes are the
properties of services. For example, printing speed,
resolution, and paper sizes are the attributes of a
printer. Unlike the traditional services that are
identified by their names, IP addresses, and port
numbers, service attributes are used to identify
services in service discovery protocols.
Service Discovery:
Service discovery is a
type of network protocols. The protocols reduce
the administrative overhead and automate con-
figuration and setup to use service. Via a set of
service discovery mechanisms, clients and services
exchange service information, properly configure,
and install necessary drivers before service usage.
Service Integration:
Service integration
enables complex services that are built from in-
dividual services. Often, a service's output is used
as the input of another service. Service integration
is also known as service composition.
Service Lookup:
Service lookup mechanisms
facilitate the matching from a client's request to
an existing service or services.
