A Comparison Study for Service Replication Protocols in MANETs

Mobile ad hoc networks (MANETs) are characterized by high dynamics in particular with respect to the formation of network partitions. Typically, one aim of MANETs is to allow for the sharing of functionality and information among the participant nodes. A paradigm that allows for functionality sharing is service orientation where functionality provided by one node is offered as a service to other nodes. The presence of unconnected partitions makes the deployed services inaccessible to some network participants. Service replication is employed as an approach to overcome this problem and to ensure higher service availability and accessibility although the partitioning behavior.
In the literature, several protocols and algorithms for service replication in MANETs have been proposed. This report identifies different criteria suitable to compare these approaches. In particular, we focus on comparing the Service Distribution Protocol (SDP), proposed in our previous work, to existing approaches. After a high-level comparison of a number of approaches, an in-depth case study that compares SDP to one representative existing approach is presented. Results show that SDP is promising and its performance comparable to traditional.
