Abstract?Flash flood refers to a phenomenon where water level raises rapidly within a short period of time. It is caused by sudden incident of heavy rainfall. Flash flood is a major problem in many countries. There is no proper remedy for flood. In existing system, people are facing drastic Human & Monetary lose due to the unexpected and sudden release of water. In the proposed system using water & flow level sensors that are deployed, monitored and gathered to the centralized server for …show more content…

A Zigbee hardware is connected to the mobiles via OTG (USB On-The-Go) for communication, when network is not present. Public can communicate to the regional server to fetch the levels of water release & emergency alert is provided in case of excess water release from the Dam. This event will happen with Network presence or without network presence. User can also make Emergency call / send SMS to the pre-stored numbers like Hospitals / Corporation / Police / Relatives. User can also fetch Safe Zone live Mapping with internet or stored images without …show more content…

A secure network will designate one special device which other devices trust for the distribution of security keys: the trust centre. Ideally, devices will have the centre trust address and initial master key preloaded; if a momentary vulnerability is allowed, it will be sent as described above. Typical applications without special security needs will use a network key provided by the trust centre (through the initially insecure channel) to communicate.

Thus, the trust centre maintains both the network key and provides point-to-point security. Devices will only accept communications originating from a key supplied by the trust centre, except for the initial master key. The security architecture is distributed among the network layers as follows:

The MAC sublayer is capable of single-hop reliable communications. As a rule, the security level it is to use is specified by the upper layers.
The network layer manages routing process, interpreting the received messages and being able to broadcast requests. Outgoing frames will use the adequate link key based on the routing if it is available; otherwise, the network key will be used to safeguard the payload from external

    4 QoS Based Protocols QoS based protocols ensure sensor nodes balance between energy consumption and pre-determined QoS metrics like delay, energy, reliability and bandwidth, before delivering data to sink node. Sensor nodes have low processing capability, low memory power and limited transmission energy in addition to energy constraints. Hence the constraints impose an important requirement on wireless sensor network QoS support mechanisms including simplicity. Traffic flows from many sensor nodes to a small subset of sink nodes in most WSN applications. QoS mechanisms must be made for unbalanced QoS-constrained traffic.

    WPA2 –Wi-Fi protected access version 2 This security was made because of the 802.11i wireless security standard. WPA2 is very similar to WPA but it uses AES – advanced encryption standard to encrypt. AES has a 128 bit key whereas DES – data encryption standard which was used before AES has a 64bit key. 64bit keys take a lot less time to break than 128bit key.

    William’s play A Streetcar Named Desire presents a variety of perspectives on relationships, especially addressing the idea that bonds which aren’t bound by trust, loyalty and lust in an even balance will inevitably fail. Tennessee Williams uses the interaction between his characters, predominantly Blanche, Mitch, Stella and Stanley; to express a variety of ideas regarding relationships. These connections can be witnessed in scenes 2, 3, 6 and 11, through the use of stage directions, dialogue and expressionism to display different perspectives of character interaction. Trust acts as the foundation to any relationship, establishing a strong link between individuals and without it, the connection will eventually disintegrate.
