In a real-time wireless TDMA environment, every packet generated by applications has a deadline associated with it. If the system cannot allocate enough resources to serve QoS defines the call blocking probability and handoff dropping probability, whereas at packet level, or MAC level, QoS defines the packet dropping probability and delay tolerance. the packet before the deadline, the packet wo...

In this paper we present the behavior of JPEG2000 coding scheme over noisy or congested communication channels and highlight the cost analysis aspect. Two error schemes are considered including bit errors and packet dropping effects. Two bit error methods are used, consisting of flipping or dropping the bits, and various packet sizes are put to the test of packet dropping. Extensive performance...

Mobile Ad-hoc NETwork (MANET) is an application of wireless network with self-configuring mobile nodes. MANET does not require any fixed infrastructure. Its development never has any threshold range. Nodes in MANET can communicate with each other if and only if all the nodes are in the same range. This wide distribution of nodes makes MANET vulnerable to various attacks, packet dropping attack ...

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 ...

----------------------------------------------------------------------ABSTRACT------------------------------------------------------------------In wireless networks, resource management is a very complicated issue because of scarcity in resources. This paper presents a fuzzy based packet dropping scheme for wireless networks in the context of future generation cellular networks. In this scheme,...

A packet dropping and message tampering attack contains data which routed between source and destination. Packet dropping attack happens accidently or deliberately on network or packet switching network. Message tampering attack causes measure problem in message transmission activity, due to unauthorized party tampered message and can change message contains so it hard to detect that tampered m...

For state estimation over a communication network, efficiency and reliability of the network are critical issues. The presence of packet dropping and communication delay can greatly impair our ability to measure and predict states. In this paper, multiple description (MD) codes, a type of network source codes, are used to compensate for this effect on Kalman filtering. We consider two packet dr...

Traffic engineering issues require major adjustments, as the DiffServ architecture is gaining ground. In addition, the measurementbased strategy shows the advantages of flexibility and easy adaptation. This article reviews measurement-based packet/cell dropping schemes. Based on the definition and investigation of a “packet shortage” phenomenon, a new dropping scheme for proportionally differen...

This paper presents a fuzzy based buffer management scheme that performs buffer allocation and packet dropping for wireless multimedia networks in the context of future generation cellular networks. In this scheme, buffers are allocated to requesting application by using buffer allocation factor and packets are dropped for an application by using dropping factor. A buffer allocation factor for ...
