In this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. The shape of ring resonator filter adding and dropping that wehave proposed is Race Track. This filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. Transmissionefficien...

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 ...

For H.264/SVC, different layers or frames have different order of precedence according to their importance on video quality and the decoding process. Network should provide more protection for high priority layers or frames when SVC stream is transmitted over IP network. This paper proposes an active queue management algorithm based on priority dropping and PID algorithm, called PID_PD, which f...

The major attack on wireless sensor network is Denial–of-service (DoS). DoS attacks like packet dropping, collisions, interference, false route, flooding and buffer overload can destroy the network. One of the most important factors of DoS attacks is packet dropping. Packet dropping means drop packets to interrupt the packet transmission process which make the communication diminish. This paper...

active queue management (aqm) plays an important role in the internet congestion control. it tries to enhance congestion control, and to achieve tradeoff between bottleneck utilization and delay. random early detection (red) is the most popular active queue management algorithm that has been implemented in the in internet routers and is trying to supply low delay and low packet loss. red algori...

Many logicians now think that in order to give a uniform solution to the paradoxes of self-reference one must revise logic by dropping one of the usual structural rules. To date almost all such approaches have focused on dropping structural transitivity or structural contraction, and have largely overlooked or ignored the prospects for resolving the paradoxes by dropping structural reflexivity....
