SCN4M-DL: An Adaptive Directory-Less Service Discovery System for MANETs

Abstract

Service discovery systems over MANETs are demanded to find available services at an appropriate cost, even if nodes in MANETs frequently move, randomly join or leave, and services may be revoked by their owners. SCN4M-DL is an adaptive directory-less service discovery system for MANETs, and it meets the above challenges by deeply coupling with underlying geographic routing algorithm and setting configurable service renewal. The storage consumption and network traffic are under control due to the adopted ring-based service register and discovery mechanism. Extensive experiments are also conducted. The result data, i.e. the discovery request's success rates and the corresponding costs, show that SCN4M-DL can adapt well to MANET's characteristics and the changes of service states.

Cross-Layer Service Discovery Mechanism for OLSRv2 Mobile Ad Hoc Networks

“…The smooth random mobility model (SRMM) is used to estimate node location at a particular time. Weng et al [ 39 ] present an adaptive directory-less service discovery system for MANETs that couples to the underlying geographic routing algorithm and sets configurable service renewal. There are other solutions where intermediate nodes answer service queries, such as [ 40 ], where Palmieri proposes a novel service discovery approach based on a fully-distributed and parallel search model that does not require any centralized intelligence, fixed roles and a stable communication infrastructure.…”
