| description |
Nowadays, according to the advances of the wireless network technologies and also
mobile computing devices the concept of ubiquitous computing environments has
become a considerable research area. Ubiquitous computing environment means an
environment which is saturated by elements or devices with capacities of computing and
communication. So, there are a lot of ways to develop and employ applications in such
environment as infrastructure, but the most effective and general one is using service
advertisements, service discovery and service remote invocation.
In an Ad-hoc network which its devices make an ubiquitous computing environment,
every device as a server node can announce various applications as services in the
environment and at the same time every device is able to listen to the network interface
and be aware of surrounding services and invoke the remote services.A mechanism which is needed to recognize surrounding services is called service
discovery, this mechanism also clears how to advertise services, and invoke them. Type
and method of discovery procedures play the critical role in quality and efficiency of
services in ubiquitous environments. Because of these properties (small and mobile)
there is a serious limitation for the resources of devices specially power resource. The
problem is that the most of service discovery protocols are not effective for wireless Ad-
Hoc networks and ubiquities environments, efficiency in case of service quality and
power consumption.
In this research a new mechanism and algorithm is designed to improve current wireless
service discovery protocols. Analysis of the results has shown that the designed
mechanism in most of the comparative parameters such as speed of service delivery,
power consumption, and coverage of the services will act much better than the current
discovery protocols.
The proposed solution is compared with (directory based and directory-less based) of
discovery protocols in ubiquitous environment in three states: mobile nodes, mobile and
static nodes, and static nodes. It can be derived that the proposed model obtains fewer
messages around 52% while maintain the same rate of service discovery and false rate
of service discovery. The reduction of the number of posts per request coupled with the
fact that devices with greater time availability transmit more responses in the proposed
model, it can be concluded that energy consumption in devices with more restrictions
will be decreased. |
