Design of a service discovery architecture for mobility-supported wired and wireless networks

Abstract

Automatic service discovery will play an essential role in future network scenario and is an important component for MANET and collaboration in ubiquitous computing environment. This paper proposes a service discovery architecture, named as SLPA (Service Location Protocol based on AMAAM) in the mobility-supported wired and wireless environment of which the underlying protocol is AMAAM which is an aggregation-based Mobile IP implementation in MANET. In SLPA, the role of the directory agent is assigned to the mobility agent in AMAAM. The mobility agent periodically beacons an advertisement message which contains both the advertisement of the directory agent in SLP and the advertisement of the mobility agent in Mobile IP. For evaluating the functional correctness of SLPA and the overhead of maintaining a service directory in MANET, we simulate SLPA and analyze the overhead of control overheads for the aggregation. Through the simulation experiments, we investigate the functional correctness of the proposed architecture and analyze the control overheads of the aggregation. © Springer-Verlag Berlin Heidelberg 2005.
