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...

We consider a grid network where nodes contain small buffers. A packet that faces a crowded buffer in its route will get extra latency and may be dropped. In this paper, we propose a novel flow control protocol called RFCC for grid networks. RFCC tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

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...

Operation without packet alignment of an all-optical packet switch is proposed and predicted feasible through a detailed trafic analysis. Packet alignment units are eliminated resulting in a simple switch architecture while optimal traffic perfarmancc is maintained through t ~ i e ~ e x ~ b i ~ ~ ~ ~ r o v ~ d e d by WDM.
