چکیده

| The performance analyses of selective packet dropping policies have usually been performed using homogeneous traac sources and under one node scenarios. In this paper we focus our attention not only to heterogeneous sources but also heterogeneous environments. We present simulation results of application level performance for heterogeneous traac sources under three diierent packet dropping schemes: Partial Packet Discard (PPD), Early Packet Discard (EPD), and Preemp-tive Partial Packet Discard (pPPD). In addition, we also present simulation results for homogeneous sources over multi-hop networks with heterogeneous packet dropping policies.

Performance of Selective Packet Dropping Schemes in Multi-hop Networks

Networked applications require good performance from the network along with a high level of predictability. One of the factors that affects application performance is the packet dropping policy adopted in the switch or router. In this paper, we evaluate the absolute performance of various packet dropping policies, and also the predictability they can provide to an application. The packet droppi...

Enhancing Application Throughput by Selective Packet Dropping

Selective packet dropping policies have been used to reduce congestion and transmission of traffic that would inevitably be retransmitted. Common dropping policies proposed are drop-tail, partial packet discard (PPD), early packet discard (EPD) and their recent variations. However, depending on various circumstances, particularly in multi-hop networking environments, application throughput may ...

Improving Bandwidth-power Efficiency of Homogeneous Wireless Networks Using On-meet Threshold Strategy (RESEARCH NOTE)

Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem.  Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...
