We have various packet marking schemes in order to trace back Dos/Ddos attackers to theirs source. A major issue in the design of a good trace back scheme by minimizing the maximum number of packets that are needed for a successful trace back. These DDos attacks have become highly distributed as well as increasingly sophisticated. …

A network congestion leading to packet loss, power over utilization due to retransmissions as well as packet drops in wireless sensor networks (WSN’s). It becomes quite important here to control and avoid such congestion’s precisely. This can be achieved using an upstream hop-by-hop protocol for congestion control (UHCC) which is proposed on a cross layer …

A sinkhole attack attempts to harm wsn’s where in an intruder attempts to redirect all network traffic towards itself, by providing false routing data. This has an adverse effect on the network load balance as well as it provides a stage for other attacks to go through as well. This makes it extremely important to …

Making use of a sleep technique the power consumption of a wireless sensor based network can be minimized using S MAC protocol. This breaks up the network into a virtual cluster. Different sleep schedules being used in each cluster leads to issues in the S MAC protocol. Our system proposes to find out the best …

As opposed to TCP Reno, the TCP Vegas in the early stages itself allows to recognize as well as avoid the periodic packet loss. In many cases it has been proved that TCP Vegas provides a better performance as compared to TCP Reno. Well even TCP Vegas has several issues which affect it’s anti congestion …
