Performance of Selective Packet Dropping Schemes in Multi-hop Networks
نویسندگان
چکیده
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 dropping schemes studied are the Partial Packet Discard (PPD), Early Packet Discard (EPD), Age Priority Packet Discarding (APPD) and the Preemptive Partial Packet Discard (pPPD). Results are provided in multihop networks for different traffic types, including IP over ATM trace data.

Performance of Selective Packet Dropping Policies in Heterogeneous Networks
| 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 sc...

متن کاملEnhancing 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 ...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

In wireless sensor networks the Packet Droppers and Modifiers are common attacks. It is very difficult to identify such attacks and this attack interrupts the communication in wireless multi hop sensor networks. In this we can identify the Packet Droppers and Packet Modifiers using ranking algorithms and packet marks. The Performance is represented using detection rate and false positive probab...
