Routing based service discovery in Mobile Ad Hoc Network
การค้นหาบริการเครือข่าย Mobile Ad Hoc Network โดยอาศัยวิธีการหาเส้นทาง
Abstract:
Mobile ad-hoc networks (MANET) are dynamic collections of mobile devices
loosely connected with no underlying infrastructure. Therefore, the stability of such
networks is less than that of a fixed network, and it has been limited by computing
power, memory size and network bandwidth. With the advent of novel technologies in
mobile and wireless networks, some real world applications require the formation of a
MANET. Examples of such applications are communications in a military battlefield,
voice transmission within limited distance of a disaster relief operation, and file and
resource sharing in a remote area.
Interesting research issues in MANET include routing protocols, configuration
management, and service discovery protocols. Recently, a number of service
discovery protocols such as UPnP [5, 23, 25], SLP [21, 23, 25] and Jini [5, 23, 25] on
a fixed network have been proposed. However, such protocols do not suite well with a
MANET environment, and would give poor performance since they operate at the
application level and mostly rely on the unstable network connectivity of MANET.
This work proposes a new service discovery protocol based on two related
concepts. They are mobile agents [1], and a MANET routing protocol called Rumor
routing [5]. The objective is to attain an effective means to discover available services
among mobile devices in MANET. The performance of the proposed protocol is
evaluated using a popular network simulator called ns-2 [19].
