Composition of Service and Protocol Specifications in Asynchronous Communication System

One of the important techniques in communication system design is the composition of service and protocol specifications. In this paper, we have presented a new approach to the composition technique based on the weak bisimulation concept. The main objective is to combine service specifications and protocol specifications individually and simultaneously. The composition technique can maintain th...

Decision Follow-Up Support Mechanism Based on Asynchronous Communication

Decision management and decision support systems are themes under investigation for several decades, and both research areas provided contributions for the quality of decision making processes. However, little work has been done in the aerea of decision follow-up, especially regarding decisions made during meetings. In this paper we analyse the concepts related to this problem and we propose a ...

The Interoperability of Location-Tracking Service based on Geographic Information

Designing a Volunteer Geographic Information-based service for rapid earth quake damages estimation

Designing a Volunteer Geographic Information-based service for rapid earth quake damages estimation Introduction The advent of Web 2.0 enables the users to interact and prepare free unlimited real time data. This advantage leads us to exploit Volunteer Geographic Information (VGI) for real time crisis management. Traditional estimation methods for earthquake damages are expensive and tim...

Service Differentiated Non-cooperative Random Access Protocol for OFDMA based Wireless Communication System

In this paper random access problem for the OFDMA based communication system is addressed in perspective of service differentiated non cooperative game for gaining distributed control over the system. In order to provide diverse QoS demands from users, an access priority based scheme for effectively supporting various ASCs (Access Service Classes) according to the different QoS (Quality of Serv...
