A simple resource advertisement and discovery protocol for large and dense MANETs

With remarkable advances in wireless technologies, applications of mobile ad hoe networks will be in widespread use in the near future. Thus, the geographical network environments may become large and dense. In such network environments, a large number of resource discovery queries may be generated when specific resources or services are needed. In this paper, we propose a simple resource advertisement and discovery (SRAD) protocol for applications in mobile ad hoc networks. The SRAD protocol self-organizes a proximity network and works in a fully distributed architecture without centralized control and management. The simulation results show that the SRAD protocol can achieve the same level of performance as in the broadcast-based protocols while generating fewer transmitted messages in large and dense mobile ad hoc networks.
