SLPManet: service location protocol for MANET

ABSTRACT

Service Discovery Protocols (SDP) allow users and applications to automatically locate services without prior configuration. Since Mobile Ad Hoc Networks (MANETs) constitute an integral part of the ubiquitous computing scenario, increasing efforts are geared toward providing service discovery in such environments. In this work, we adapt the widely employed Service Discovery Protocols (SDP) Version 2 to MANETs. We implement and analyze the adapted protocol, SLPManet, using Network Simulator Version 2. Consequently, we propose a caching modification that increases the discovery success by 38% for poorly performing scenarios, as well as reduces the aggregate bandwidth consumption and average lookup latency by up to 98%.
