Recently, several router-based congestion control mechanisms have been proposed to support an end-to-end congestion control mechanism of TCP (Transmission Control Protocol). In this paper, we focus on a RED (Random Early Detection) router, which is one of promising router-based congestion control mechanisms. The RED router randomly drops the arriving packet by alignment probability to an averag...

Future microcellular systems will require distributed network control. A packet-switched network is particularly suitable for this requirement. Moreover, packet switching naturally accommodates speech activity detection to improve Vation-ALOHA protocol for packet speech transmission from wireless terminals to a base station. Because PRMA is a statistical multiplexer, the channel becomes congest...

Collection of wireless nodes forms together to communicate each other in the network without infrastructure less and any access point along with characteristics freedom mobility is called Mobile Adhoc Network. Transmitting packets from source destination plays vital role MANET. When a Packet not delivered properly at , its affects performance Due this can subject falls on packet missing also va...

In this paper, we examine the behavior of the JPEG2000 coding scheme over noisy or congested communication channels and highlight a cost policy aspect. Two error schemes are considered, involving bit errors (noisy channel) and packet-dropping (congested channel) effects. Two bit error methods are used, consisting of flipping or eliminating the bits, and various packet sizes are put to the test ...

In stateless core (SCORE) networks, edge routers maintain per flow state while core routers do not. Core stateless fair queuing (CSFQ) has been proposed for approximating the operation of per-flow queuing techniques in SCORE networks. However, the packet dropping probability offered by CSFQ suits only UDP flows. Thus, CSFQ cannot achieve fair bandwidth allocation for TCP flows. This paper propo...

Recent studies have shown that the superposition of packet sequences generated by packetized voice sources with speech detection exhibit high burstiness due to inherent correlations between successive interarrival times in the superposition stream. In a packet voice multiplexer without bit dropping, these correlations tend to cause significantly larger queueing delays and packet losses than wou...
