Packet loss detection using CPR and WCPR in diverse platforms

چکیده
In this paper loss of packets in TCP is detected using two diverse methods CPR (Constant Packet Re-arranging) and WCPR (Without Constant Packet Re-arranging) in diverse platforms. This paper proposes a new version of the TCP which gives the high throughput when the packet rearranging occurs and in another case if the packet rearranging is not occurs then in that case also it is friendly to other version of the TCP. The key feature of Constant packet rearranging is that duplicate ACKs are not used as an indication of packet loss. Instead the timer is used to detect the packet loss From a computational view-point, CPR is more demanding than WCPR. Because CPR does not rely on duplicate acknowledgments, packet rearranging (including out-or-order acknowledgments) has no effect on CPR performance.

By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
متن کاملUnauthenticated event detection in wireless sensor networks using sensors co-coverage
Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...
