AB  - Due to the remote wireless nature and human unattended environment of WSN, they are more
vulnerable to various types of attacks and intruders may visit these networks purposely or unintentionally. The
algorithms proposed in order to detect if any intruder is inside the network and to detect the wormhole and
black hole attacks. In this detection technique it tries to prevent the attacks in LEACH protocol in a wireless
sensor networks using the multiple base stations and key. Since, LEACH protocol is used the consumption of
energy is also reduced to maximum extent. This in turn reduces the overhead and data delivery increases. As
multiple base stations are employed data gets delivered cent percent. Since, LEACH protocol is used, it
guarantees power supply for a considerable amount of time with extra energy. This ensures that the packet
delivery ratio has increased prolonging the lifetime of the network. The individual nodes are given more
security, adding security to nodes will consume more energy thus reducing the lifetime of the network. If the
nodes are solar aware, the energy level gets equalised and also surplus energy may be obtained because of
usage of LEACH protocol. The proposed protocols are made to detect and prevent the attacks thus controlling
the overhead, increasing packets delivered and extending the lifetime of the wireless sensor networks.
