Hierarchical Information Acquisition Scheme on the Local Broadcasting System
نویسندگان
چکیده
In this paper, it is proposed the information delivery system that the transmission signal embraces together the wide-area information and the local area information. The distant user from the base station receives the wide-area information only and the nearby user receives together the widearea information and the local-area information. The proposed system uses the code shift keying(CSK) for transmitting the local-area information and the amplitude shift keying(ASK) for the wide-area information. In the proposed system, the broadcast information is hierarchized by combining ASK with CSK.

Broadcasting is one of the most fundamental operations in mobile ad hoc networks. Broadcasting serves as a building block in many routing protocols. The simplest approach for broadcasting is flooding. However, it generates many redundant messages that cause to loss of scarce resources such bandwidth and battery powers and it may lead to contention, collision and extreme decrease of network perf...

متن کاملDecentralized Event-Triggered Broadcasts over Networked Control Systems
This paper examines event-triggered broadcasting of state information in distributed networked systems. Event-triggering has the agent broadcast its state information when its local “error” signal exceeds a given threshold. We present a decentralized approach for determining event-triggering thresholds for nonlinear subsystems with the assumption that each agent only has access to its local sta...
