Abstract

The Service Distribution Protocol (SDP) for Mobile Ad Hoc Networks (MANETs) is a service replication protocol which aims to increase the service availability despite the challenging nature of MANETs. SDP is an interest-based protocol which can achieve an efficient service replication process and produce a close to optimal service distribution over the network based on a variant service popularity. In this work, the assumptions made by the original authors of SDP in order to elaborate their protocol, are being discussed and deprecated from the perspective of utilizing the resources of servers. Moreover, the need to add new features for SDP to enable it to operate under more realistic assumptions - in particular limited server resources - are mentioned and analyzed. A new interest-based mechanism to manage the load of the SDP servers (providers) is introduced. Finally, based on a detailed simulation using the Opnet® Modeler® Wireless simulator, the proposed load balancing mechanism has shown promising results.
