Analysis of Packet Dropping and End to End Delay in WSN using Routing Algorithm

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 proposed EQSR (energy Efficient and QoS multipath routing) in which drop packets and end-to-end delay is concluded using two pass algorithms which firstly examine drop packets and then the attack of packet loss. In this algorithm also reduced the dropping packets by decreasing the end –todelay in wireless sensor network.
