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].
