The Service Distribution Protocol for MANETs – Criteria and Performance Analysis

Sharing network resources in mobile ad hoc networks (MANETs) enable the provisioning of the main required network functionalities. Service orientation is a promising candidate for allowing mobile nodes to share their functionalities as services. Unfortunately, typical characteristics of MANETs like their ever-changing topology and limited resources have a dramatic negative effect on service availability and accessibility. The Service Distribution Protocol (SDP)  [1] for MANETs introduces a service replication/hibernation approach to increase the service availability in MANETs. Based on the service popularity at any given time, the protocol provides a MANETs’ architecture independent mechanism which ensures higher service availability and accessibility.
In this paper, SDP is presented and applied in a restrictive environment with more constraints. By elaborating an extensive detailed simulation, a set of measurements and performance criteria are examined in order to highlight the efficiency of SDP.
